4 *
5 * HTML Purifier is an HTML filter that will take an arbitrary snippet of
6 * HTML and rigorously test, validate and filter it into a version that
7 * is safe for output onto webpages. It achieves this by:
8 *
9 * -# Lexing (parsing into tokens) the document,
10 * -# Executing various strategies on the tokens:
11 * -# Removing all elements not in the whitelist,
12 * -# Making the tokens well-formed,
13 * -# Fixing the nesting of the nodes, and
14 * -# Validating attributes of the nodes; and
15 * -# Generating HTML from the purified tokens.
16 *
17 * However, most users will only need to interface with the HTMLPurifier
18 * and HTMLPurifier_Config.

120 // for parsing/rendering purposes.
121 // The above characters cover the majority of Western font
122 // names.
123 // - Arbitrary Unicode characters not in ASCII. Because
124 // most parsers give little thought to Unicode, treatment
125 // of these codepoints is basically uniform, even for
126 // punctuation-like codepoints. These characters can
127 // show up in non-Western pages and are supported by most
128 // major browsers, for example: "MS 明朝" is a
129 // legitimate font-name
130 // <http://ja.wikipedia.org/wiki/MS_明朝>. See
131 // the CSS3 spec for more examples:
132 // <http://www.w3.org/TR/2011/WD-css3-fonts-20110324/localizedfamilynames.png>
133 // You can see live samples of these on the Internet:
134 // <http://www.google.co.jp/search?q=font-family+MS+明朝|ゴシック>
135 // However, most of these fonts have ASCII equivalents:
136 // for example, 'MS Mincho', and it's considered
137 // professional to use ASCII font names instead of
138 // Unicode font names. Thanks Takeshi Terada for
139 // providing this information.
140 // The following characters, to my knowledge, have not been
141 // used to name font names.
142 // - Single quote. While theoretically you might find a
143 // font name that has a single quote in its name (serving
144 // as an apostrophe, e.g. Dave's Scribble), I haven't
145 // been able to find any actual examples of this.
146 // Internet Explorer's cssText translation (which I
147 // believe is invoked by innerHTML) normalizes any
148 // quoting to single quotes, and fails to escape single
149 // quotes. (Note that this is not IE's behavior for all
150 // CSS properties, just some sort of special casing for
151 // font-family). So a single quote *cannot* be used
152 // safely in the font-family context if there will be an
153 // innerHTML/cssText translation. Note that Firefox 3.x
154 // does this too.
155 // - Double quote. In IE, these get normalized to
156 // single-quotes, no matter what the encoding. (Fun
157 // fact, in IE8, the 'content' CSS property gained
158 // support, where they special cased to preserve encoded
159 // double quotes, but still translate unadorned double
160 // quotes into single quotes.) So, because their
161 // fixpoint behavior is identical to single quotes, they
162 // cannot be allowed either. Firefox 3.x displays
163 // single-quote style behavior.
164 // - Backslashes are reduced by one (so \\ -> \) every
165 // iteration, so they cannot be used safely. This shows
166 // up in IE7, IE8 and FF3
167 // - Semicolons, commas and backticks are handled properly.
168 // - The rest of the ASCII punctuation is handled properly.
169 // We haven't checked what browsers do to unadorned
170 // versions, but this is not important as long as the
171 // browser doesn't /remove/ surrounding quotes (as IE does
172 // for HTML).
173 //
174 // With these results in hand, we conclude that there are
175 // various levels of safety:
176 // - Paranoid: alphanumeric, spaces and dashes(?)
177 // - International: Paranoid + non-ASCII Unicode
178 // - Edgy: Everything except quotes, backslashes
179 // - NoJS: Standards compliance, e.g. sod IE. Note that
180 // with some judicious character escaping (since certain
181 // types of escaping doesn't work) this is theoretically
182 // OK as long as innerHTML/cssText is not called.
183 // We believe that international is a reasonable default
184 // (that we will implement now), and once we do more
185 // extensive research, we may feel comfortable with dropping
186 // it down to edgy.

3/**
4 * Definition for tables. The general idea is to extract out all of the
5 * essential bits, and then reconstruct it later.
6 *
7 * This is a bit confusing, because the DTDs and the W3C
8 * validators seem to disagree on the appropriate definition. The
9 * DTD claims:
10 *
11 * (CAPTION?, (COL*|COLGROUP*), THEAD?, TFOOT?, TBODY+)
12 *
13 * But actually, the HTML4 spec then has this to say:
14 *
15 * The TBODY start tag is always required except when the table
16 * contains only one table body and no table head or foot sections.
17 * The TBODY end tag may always be safely omitted.
18 *
19 * So the DTD is kind of wrong. The validator is, unfortunately, kind
20 * of on crack.
21 *
22 * The definition changed again in XHTML1.1; and in my opinion, this
23 * formulation makes the most sense.
24 *
25 * caption?, ( col* | colgroup* ), (( thead?, tfoot?, tbody+ ) | ( tr+ ))
26 *
27 * Essentially, we have two modes: thead/tfoot/tbody mode, and tr mode.
28 * If we encounter a thead, tfoot or tbody, we are placed in the former
29 * mode, and we *must* wrap any stray tr segments with a tbody. But if
30 * we don't run into any of them, just have tr tags is OK.

1Attr.ClassUseCDATA
2TYPE: bool/null
3DEFAULT: null
4VERSION: 4.0.0
5--DESCRIPTION--
6If null, class will auto-detect the doctype and, if matching XHTML 1.1 or
7XHTML 2.0, will use the restrictive NMTOKENS specification of class. Otherwise,
8it will use a relaxed CDATA definition. If true, the relaxed CDATA definition
9is forced; if false, the NMTOKENS definition is forced. To get behavior
10of HTML Purifier prior to 4.0.0, set this directive to false.
11
12Some rational behind the auto-detection:
13in previous versions of HTML Purifier, it was assumed that the form of
14class was NMTOKENS, as specified by the XHTML Modularization (representing
15XHTML 1.1 and XHTML 2.0). The DTDs for HTML 4.01 and XHTML 1.0, however
16specify class as CDATA. HTML 5 effectively defines it as CDATA, but
17with the additional constraint that each name should be unique (this is not
18explicitly outlined in previous specifications).

11<ul>
12 <li>Always applies to inline elements or text in the root node,</li>
13 <li>Applies to inline elements or text with double newlines in nodes

19 We do not use <code>br</code> tags for paragraphing, as that is

23 To prevent auto-paragraphing as a content-producer, refrain from using
24 double-newlines except to specify a new paragraph or in contexts where
25 it has special meaning (whitespace usually has no meaning except in
26 tags like <code>pre</code>, so this should not be difficult.) To prevent
27 the paragraphing of inline text adjacent to block elements, wrap them
28 in <code>div</code> tags (the behavior is slightly different outside of
29 the root node.)

1AutoFormat.RemoveEmpty
2TYPE: bool
3VERSION: 3.2.0
4DEFAULT: false
5--DESCRIPTION--
6<p>
7 When enabled, HTML Purifier will attempt to remove empty elements that
8 contribute no semantic information to the document. The following types
9 of nodes will be removed:
10</p>
11<ul><li>
12 Tags with no attributes and no content, and that are not empty
13 elements (remove <code>&lt;a&gt;&lt;/a&gt;</code> but not
14 <code>&lt;br /&gt;</code>), and
15 </li>
16 <li>
17 Tags with no content, except for:<ul>
18 <li>The <code>colgroup</code> element, or</li>
19 <li>
20 Elements with the <code>id</code> or <code>name</code> attribute,
21 when those attributes are permitted on those elements.
22 </li>
23 </ul></li>
24</ul>
25<p>
26 Please be very careful when using this functionality; while it may not
27 seem that empty elements contain useful information, they can alter the
28 layout of a document given appropriate styling. This directive is most
29 useful when you are processing machine-generated HTML, please avoid using
30 it on regular user HTML.
31</p>
32<p>
33 Elements that contain only whitespace will be treated as empty. Non-breaking
34 spaces, however, do not count as whitespace. See
35 %AutoFormat.RemoveEmpty.RemoveNbsp for alternate behavior.
36</p>
37<p>
38 This algorithm is not perfect; you may still notice some empty tags,
39 particularly if a node had elements, but those elements were later removed
40 because they were not permitted in that context, or tags that, after
41 being auto-closed by another tag, where empty. This is for safety reasons
42 to prevent clever code from breaking validation. The general rule of thumb:
43 if a tag looked empty on the way in, it will get removed; if HTML Purifier
44 made it empty, it will stay.

1Core.Encoding
2TYPE: istring

4--DESCRIPTION--
5If for some reason you are unable to convert all webpages to UTF-8, you can
6use this directive as a stop-gap compatibility change to let HTML Purifier
7deal with non UTF-8 input. This technique has notable deficiencies:
8absolutely no characters outside of the selected character encoding will be
9preserved, not even the ones that have been ampersand escaped (this is due
10to a UTF-8 specific <em>feature</em> that automatically resolves all
11entities), making it pretty useless for anything except the most I18N-blind
12applications, although %Core.EscapeNonASCIICharacters offers fixes this
13trouble with another tradeoff. This directive only accepts ISO-8859-1 if
14iconv is not enabled.

6This directive overcomes a deficiency in %Core.Encoding by blindly
7converting all non-ASCII characters into decimal numeric entities before
8converting it to its native encoding. This means that even characters that
9can be expressed in the non-UTF-8 encoding will be entity-ized, which can
10be a real downer for encodings like Big5. It also assumes that the ASCII
11repetoire is available, although this is the case for almost all encodings.
12Anyway, use UTF-8!

16 tag, which defines some presentational changes but does not hide its

9 If you would like users to be able to define external stylesheets, but
10 only allow them to specify CSS declarations for a specific node and
11 prevent them from fiddling with other elements, use this directive.
12 It accepts any valid CSS selector, and will prepend this to any
13 CSS declaration extracted from the document. For example, if this
14 directive is set to <code>#user-content</code> and a user uses the
15 selector <code>a:hover</code>, the final selector will be
16 <code>#user-content a:hover</code>.
17</p>
18<p>
19 The comma shorthand may be used; consider the above example, with
20 <code>#user-content, #user-content2</code>, the final selector will
21 be <code>#user-content a:hover, #user-content2 a:hover</code>.
22</p>
23<p>
24 <strong>Warning:</strong> It is possible for users to bypass this measure
25 using a naughty + selector. This is a bug in CSS Tidy 1.3, not HTML

61 <strong>Warning:</strong> It is possible for a user to mount an
62 imagecrash attack using this CSS. Counter-measures are difficult;
63 it is not simply enough to limit the range of CSS lengths (using
64 relative lengths with many nesting levels allows for large values
65 to be attained without actually specifying them in the stylesheet),
66 and the flexible nature of selectors makes it difficult to selectively
67 disable lengths on image tags (HTML Purifier, however, does disable
68 CSS width and height in inline styling). There are probably two effective
69 counter measures: an explicit width and height set to auto in all
70 images in your document (unlikely) or the disabling of width and
71 height (somewhat reasonable). Whether or not these measures should be
72 used is left to the reader.

6A regexp, which if it matches the body of a comment, indicates that

9<strong>Warning:</strong> Make sure you specify
10correct anchor metacharacters <code>^regex$</code>, otherwise you may accept
11comments that you did not mean to! In particular, the regex <code>/foo|bar/</code>
12is probably not sufficiently strict, since it also allows <code>foobar</code>.

7 If HTML Purifier's tag set is unsatisfactory for your needs, you can

14 If you attempt to allow an element that HTML Purifier does not know
15 about, HTML Purifier will raise an error. You will need to manually
16 tell HTML Purifier about this element by using the

8 A doctype comes with a set of usual modules to use. Without having
9 to mucking about with the doctypes, you can quickly activate or

6
7<p>
8 Unique identifier for a custom-built HTML definition. If you edit
9 the raw version of the HTMLDefinition, introducing changes that the
10 configuration object does not reflect, you must specify this variable.
11 If you change your custom edits, you should change this directive, or
12 clear your cache. Example:
13</p>
14<pre>
15$config = HTMLPurifier_Config::createDefault();
16$config->set('HTML', 'DefinitionID', '1');
17$def = $config->getHTMLDefinition();
18$def->addAttribute('a', 'tabindex', 'Number');
19</pre>
20<p>
21 In the above example, the configuration is still at the defaults, but
22 using the advanced API, an extra attribute has been added. The
23 configuration object normally has no way of knowing that this change
24 has taken place, so it needs an extra directive: %HTML.DefinitionID.
25 If someone else attempts to use the default configuration, these two
26 pieces of code will not clobber each other in the cache, since one has
27 an extra directive attached to it.
28</p>
29<p>
30 You <em>must</em> specify a value to this directive to use the
31 advanced API features.

7<p>
8 Munges all browsable (usually http, https and ftp)
9 absolute URIs into another URI, usually a URI redirection service.
10 This directive accepts a URI, formatted with a <code>%s</code> where
11 the url-encoded original URI should be inserted (sample:
12 <code>http://www.google.com/url?q=%s</code>).
13</p>
14<p>
15 Uses for this directive:
16</p>
17<ul>
18 <li>
19 Prevent PageRank leaks, while being fairly transparent
20 to users (you may also want to add some client side JavaScript to
21 override the text in the statusbar). <strong>Notice</strong>:
22 Many security experts believe that this form of protection does not deter spam-bots.
23 </li>
24 <li>
25 Redirect users to a splash page telling them they are leaving your
26 website. While this is poor usability practice, it is often mandated
27 in corporate environments.
28 </li>
29</ul>
30<p>
31 Prior to HTML Purifier 3.1.1, this directive also enabled the munging
32 of browsable external resources, which could break things if your redirection
33 script was a splash page or used <code>meta</code> tags. To revert to
34 previous behavior, please use %URI.MungeResources.
35</p>
36<p>
37 You may want to also use %URI.MungeSecretKey along with this directive
38 in order to enforce what URIs your redirector script allows. Open
39 redirector scripts can be a security risk and negatively affect the
40 reputation of your domain name.
41</p>
42<p>
43 Starting with HTML Purifier 3.1.1, there is also these substitutions:
44</p>
45<table>

78 was that they couldn't be a through f. r is for resource (I would have preferred
79 e, but you take what you can get), n is for name, m
80 was picked because it came after n (and I couldn't use a), p is for

1URI.MungeSecretKey
2TYPE: string/null
3VERSION: 3.1.1
4DEFAULT: NULL
5--DESCRIPTION--
6<p>
7 This directive enables secure checksum generation along with %URI.Munge.
8 It should be set to a secure key that is not shared with anyone else.
9 The checksum can be placed in the URI using %t. Use of this checksum
10 affords an additional level of protection by allowing a redirector
11 to check if a URI has passed through HTML Purifier with this line:
12</p>
13
14<pre>$checksum === hash_hmac("sha256", $url, $secret_key)</pre>
15
16<p>
17 If the output is TRUE, the redirector script should accept the URI.
18</p>
19
20<p>
21 Please note that it would still be possible for an attacker to procure
22 secure hashes en-mass by abusing your website's Preview feature or the
23 like, but this service affords an additional level of protection
24 that should be combined with website blacklisting.
25</p>
26
27<p>
28 Remember this has no effect if %URI.Munge is not on.

4--DESCRIPTION--
5If this is set to true (which it is by default), you can override
6%URI.AllowedSchemes by simply registering a HTMLPurifier_URIScheme to the
7registry. If false, you will also have to update that directive in order
8to add more schemes.

1URI.SafeIframeRegexp
2TYPE: string/null
3VERSION: 4.4.0
4DEFAULT: NULL
5--DESCRIPTION--
6<p>
7 A PCRE regular expression that will be matched against an iframe URI. This is
8 a relatively inflexible scheme, but works well enough for the most common
9 use-case of iframes: embedded video. This directive only has an effect if
10 %HTML.SafeIframe is enabled. Here are some example values:
11</p>
12<ul>
13 <li><code>%^http://www.youtube.com/embed/%</code> - Allow YouTube videos</li>
14 <li><code>%^http://player.vimeo.com/video/%</code> - Allow Vimeo videos</li>
15 <li><code>%^http://(www.youtube.com/embed/|player.vimeo.com/video/)%</code> - Allow both</li>
16</ul>
17<p>
18 Note that this directive does not give you enough granularity to, say, disable
19 all <code>autoplay</code> videos. Pipe up on the HTML Purifier forums if this
20 is a capability you want.

3/**
4 * Forgivingly lexes HTML (SGML-style) markup into tokens.
5 *
6 * A lexer parses a string of SGML-style markup and converts them into
7 * corresponding tokens. It doesn't check for well-formedness, although its
8 * internal mechanism may make this automatic (such as the case of
9 * HTMLPurifier_Lexer_DOMLex). There are several implementations to choose
10 * from.
11 *
12 * A lexer is HTML-oriented: it might work with XML, but it's not
13 * recommended, as we adhere to a subset of the specification for optimization
14 * reasons. This might change in the future. Also, most tokenizers are not
15 * expected to handle DTDs or PIs.
16 *
17 * This class should not be directly instantiated, but you may use create() to
18 * retrieve a default copy of the lexer. Being a supertype, this class
19 * does not actually define any implementation, but offers commonly used
20 * convenience functions for subclasses.
21 *
22 * @note The unit tests will instantiate this class for testing purposes, as
23 * many of the utility functions require a class to be instantiated.
24 * This means that, even though this class is not runnable, it will
25 * not be declared abstract.
26 *
27 * @par
28 *
29 * @note
30 * We use tokens rather than create a DOM representation because DOM would:
31 *
32 * @par
33 * -# Require more processing and memory to create,
34 * -# Is not streamable, and
35 * -# Has the entire document structure (html and body not needed).
36 *
37 * @par
38 * However, DOM is helpful in that it makes it easy to move around nodes
39 * without a lot of lookaheads to see when a tag is closed. This is a
40 * limitation of the token system and some workarounds would be nice.

3/**
4 * Parser that uses PHP 5's DOM extension (part of the core).
5 *
6 * In PHP 5, the DOM XML extension was revamped into DOM and added to the core.
7 * It gives us a forgiving HTML parser, which we use to transform the HTML
8 * into a DOM, and then into the tokens. It is blazingly fast (for large
9 * documents, it performs twenty times faster than
10 * HTMLPurifier_Lexer_DirectLex,and is the default choice for PHP 5.
11 *
12 * @note Any empty elements will have empty tokens associated with them, even if
13 * this is prohibited by the spec. This is cannot be fixed until the spec
14 * comes into play.
15 *
16 * @note PHP's DOM extension does not actually parse any entities, we use
17 * our own function to do that.
18 *
19 * @warning DOM tends to drop whitespace, which may wreak havoc on indenting.
20 * If this is a huge problem, due to the fact that HTML is hand
21 * edited and you are unable to get a parser cache that caches the
22 * the output of HTML Purifier while keeping the original HTML lying
23 * around, you may want to run Tidy on the resulting output or use
24 * HTMLPurifier_DirectLex

4 * Takes a well formed list of tokens and fixes their nesting.
5 *
6 * HTML elements dictate which elements are allowed to be their children,
7 * for example, you can't have a p tag in a span tag. Other elements have
8 * much more rigorous definitions: tables, for instance, require a specific
9 * order for their elements. There are also constraints not expressible by
10 * document type definitions, such as the chameleon nature of ins/del
11 * tags and global child exclusions.
12 *
13 * The first major objective of this strategy is to iterate through all
14 * the nodes and determine whether or not their children conform to the
15 * element's definition. If they do not, the child definition may
16 * optionally supply an amended list of elements that is valid or
17 * require that the entire node be deleted (and the previous node
18 * rescanned).
19 *
20 * The second objective is to ensure that explicitly excluded elements of
21 * an element do not appear in its children. Code that accomplishes this
22 * task is pervasive through the strategy, though the two are distinct tasks
23 * and could, theoretically, be seperated (although it's not recommended).
24 *
25 * @note Whether or not unrecognized children are silently dropped or
26 * translated into text depends on the child definitions.

3/**
4 * Chainable filters for custom URI processing.
5 *
6 * These filters can perform custom actions on a URI filter object,
7 * including transformation or blacklisting. A filter named Foo
8 * must have a corresponding configuration directive %URI.Foo,
9 * unless always_load is specified to be true.
10 *
11 * The following contexts may be available while URIFilters are being
12 * processed:
13 *
14 * - EmbeddedURI: true if URI is an embedded resource that will
15 * be loaded automatically on page load
16 * - CurrentToken: a reference to the token that is currently
17 * being processed
18 * - CurrentAttr: the name of the attribute that is currently being
19 * processed
20 * - CurrentCSSProperty: the name of the CSS property that is
21 * currently being processed (if applicable)
22 *
23 * @warning This filter is called before scheme object validation occurs.
24 * Make sure, if you require a specific scheme object, you
25 * you check that it exists. This allows filters to convert
26 * proprietary URI schemes into regular ones.

4 * A zipper is a purely-functional data structure which contains
5 * a focus that can be efficiently manipulated. It is known as
6 * a "one-hole context". This mutable variant implements a zipper
7 * for a list as a pair of two arrays, laid out as follows:
8 *
9 * Base list: 1 2 3 4 [ ] 6 7 8 9
10 * Front list: 1 2 3 4
11 * Back list: 9 8 7 6
12 *
13 * User is expected to keep track of the "current element" and properly
14 * fill it back in as necessary. (ToDo: Maybe it's more user friendly
15 * to implicitly track the current element?)
16 *
17 * Nota bene: the current class gets confused if you try to store NULLs

3 * Website: http://sourceforge.net/projects/simplehtmldom/
4 * Additional projects that may be used: http://sourceforge.net/projects/debugobject/
5 * Acknowledge: Jose Solorzano (https://sourceforge.net/projects/php-html/)
6 * Contributions by:
7 * Yousuke Kumakura (Attribute filters)
8 * Vadim Voituk (Negative indexes supports of "find" method)
9 * Antcs (Constructor with automatically load contents either text or file/url)
10 *
11 * all affected sections have comments starting with "PaperG"
12 *
13 * Paperg - Added case insensitive testing of the value of the selector.
14 * Paperg - Added tag_start for the starting index of tags - NOTE: This works but not accurately.
15 * This tag_start gets counted AFTER \r\n have been crushed out, and after the remove_noice calls so it will not reflect the REAL position of the tag in the source,
16 * it will almost always be smaller by some amount.
17 * We use this to determine how far into the file the tag in question is. This "percentage will never be accurate as the $dom->size is the "real" number of bytes the dom was created from.
18 * but for most purposes, it's a really good estimation.
19 * Paperg - Added the forceTagsClosed to the dom constructor. Forcing tags closed is great for malformed html, but it CAN lead to parsing errors.
20 * Allow the user to tell us how much they trust the html.
21 * Paperg add the text and plaintext to the selectors for the find syntax. plaintext implies text in the innertext of a node. text implies that the tag is a text node.
22 * This allows for us to find tags based on the text they contain.
23 * Create find_ancestor_tag to see if a tag is - at any level - inside of another specific tag.
24 * Paperg: added parse_charset so that we know about the character set of the source document.
25 * NOTE: If the user's system has a routine called get_last_retrieve_url_contents_content_type availalbe, we will assume it's returning the content-type header from the
26 * last transfer or curl_exec, and we will parse that and use it in preference to any other method of charset detection.
27 *
28 * Found infinite loop in the case of broken html in restore_noise. Rewrote to protect from that.
29 * PaperG (John Schlick) Added get_display_size for "IMG" tags.
