- *

- * HTML Purifier is an HTML filter that will take an arbitrary snippet of

- * HTML and rigorously test, validate and filter it into a version that

- * is safe for output onto webpages. It achieves this by:

- *

- *  -# Lexing (parsing into tokens) the document,

- *  -# Executing various strategies on the tokens:

- *      -# Removing all elements not in the whitelist,

- *      -# Making the tokens well-formed,

- *      -# Fixing the nesting of the nodes, and

- *      -# Validating attributes of the nodes; and

- *  -# Generating HTML from the purified tokens.

- *

- * However, most users will only need to interface with the HTMLPurifier

- * and HTMLPurifier_Config.

-            //  The above characters cover the majority of Western font

-            //    legitimate font-name

-            //    <http://ja.wikipedia.org/wiki/MS_明朝>.  See

-            //    the CSS3 spec for more examples:

-            //    <http://www.w3.org/TR/2011/WD-css3-fonts-20110324/localizedfamilynames.png>

-            //    You can see live samples of these on the Internet:

-            //    <http://www.google.co.jp/search?q=font-family+ＭＳ+明朝|ゴシック>

-            //    However, most of these fonts have ASCII equivalents:

-            //    for example, 'MS Mincho', and it's considered

-            //    professional to use ASCII font names instead of

-            //    Unicode font names.  Thanks Takeshi Terada for

-            //    providing this information.

-            //  The following characters, to my knowledge, have not been

-            //  used to name font names.

-            //  - Single quote.  While theoretically you might find a

-            //    font name that has a single quote in its name (serving

-            //    as an apostrophe, e.g. Dave's Scribble), I haven't

-            //    been able to find any actual examples of this.

-            //    Internet Explorer's cssText translation (which I

-            //    believe is invoked by innerHTML) normalizes any

-            //    quoting to single quotes, and fails to escape single

-            //    quotes.  (Note that this is not IE's behavior for all

-            //    CSS properties, just some sort of special casing for

-            //    font-family).  So a single quote *cannot* be used

-            //    safely in the font-family context if there will be an

-            //    innerHTML/cssText translation.  Note that Firefox 3.x

-            //    does this too.

-            //  - Double quote.  In IE, these get normalized to

-            //    single-quotes, no matter what the encoding.  (Fun

-            //    fact, in IE8, the 'content' CSS property gained

-            //    support, where they special cased to preserve encoded

-            //    double quotes, but still translate unadorned double

-            //    quotes into single quotes.)  So, because their

-            //    fixpoint behavior is identical to single quotes, they

-            //    cannot be allowed either.  Firefox 3.x displays

-            //    single-quote style behavior.

-            //  - Backslashes are reduced by one (so \\ -> \) every

-            //    iteration, so they cannot be used safely.  This shows

-            //    up in IE7, IE8 and FF3

-            //  - Semicolons, commas and backticks are handled properly.

-            //  - The rest of the ASCII punctuation is handled properly.

-            // We haven't checked what browsers do to unadorned

-            // versions, but this is not important as long as the

-            // browser doesn't /remove/ surrounding quotes (as IE does

-            // for HTML).

-            //

-            // With these results in hand, we conclude that there are

-            // various levels of safety:

-            //  - Paranoid: alphanumeric, spaces and dashes(?)

-            //  - International: Paranoid + non-ASCII Unicode

-            //  - Edgy: Everything except quotes, backslashes

-            //  - NoJS: Standards compliance, e.g. sod IE. Note that

-            //    with some judicious character escaping (since certain

-            //    types of escaping doesn't work) this is theoretically

-            //    OK as long as innerHTML/cssText is not called.

-            // We believe that international is a reasonable default

-            // (that we will implement now), and once we do more

-            // extensive research, we may feel comfortable with dropping

-            // it down to edgy.

-

-            // Edgy: alphanumeric, spaces, dashes, underscores and Unicode.  Use of

-            // str(c)spn assumes that the string was already well formed

-            // Unicode (which of course it is).

-/**

- * Definition for tables.  The general idea is to extract out all of the

- * essential bits, and then reconstruct it later.

- *

- * This is a bit confusing, because the DTDs and the W3C

- * validators seem to disagree on the appropriate definition. The

- * DTD claims:

- *

- *      (CAPTION?, (COL*|COLGROUP*), THEAD?, TFOOT?, TBODY+)

- *

- * But actually, the HTML4 spec then has this to say:

- *

- *      The TBODY start tag is always required except when the table

- *      contains only one table body and no table head or foot sections.

- *      The TBODY end tag may always be safely omitted.

- *

- * So the DTD is kind of wrong.  The validator is, unfortunately, kind

- * of on crack.

- *

- * The definition changed again in XHTML1.1; and in my opinion, this

- * formulation makes the most sense.

- *

- *      caption?, ( col* | colgroup* ), (( thead?, tfoot?, tbody+ ) | ( tr+ ))

- *

- * Essentially, we have two modes: thead/tfoot/tbody mode, and tr mode.

- * If we encounter a thead, tfoot or tbody, we are placed in the former

- * mode, and we *must* wrap any stray tr segments with a tbody. But if

- * we don't run into any of them, just have tr tags is OK.

-Attr.ClassUseCDATA

-TYPE: bool/null

-DEFAULT: null

-VERSION: 4.0.0

---DESCRIPTION--

-If null, class will auto-detect the doctype and, if matching XHTML 1.1 or

-XHTML 2.0, will use the restrictive NMTOKENS specification of class. Otherwise,

-it will use a relaxed CDATA definition.  If true, the relaxed CDATA definition

-is forced; if false, the NMTOKENS definition is forced.  To get behavior

-of HTML Purifier prior to 4.0.0, set this directive to false.

-

-Some rational behind the auto-detection:

-in previous versions of HTML Purifier, it was assumed that the form of

-class was NMTOKENS, as specified by the XHTML Modularization (representing

-XHTML 1.1 and XHTML 2.0).  The DTDs for HTML 4.01 and XHTML 1.0, however

-specify class as CDATA.  HTML 5 effectively defines it as CDATA, but

-with the additional constraint that each name should be unique (this is not

-explicitly outlined in previous specifications).

-</p>

-  <li>Always applies to inline elements or text in the root node,</li>

-  <li>Applies to inline elements or text with double newlines in nodes

-      that allow paragraph tags,</li>

-<p>

-  <code>p</code> tags must be allowed for this directive to take effect.

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

-  semantically incorrect.

-</p>

-<p>

-  To prevent auto-paragraphing as a content-producer, refrain from using

-  double-newlines except to specify a new paragraph or in contexts where

-  it has special meaning (whitespace usually has no meaning except in

-  tags like <code>pre</code>, so this should not be difficult.) To prevent

-  the paragraphing of inline text adjacent to block elements, wrap them

-  in <code>div</code> tags (the behavior is slightly different outside of

-  the root node.)

-AutoFormat.RemoveEmpty

---DESCRIPTION--

-<p>

-  When enabled, HTML Purifier will attempt to remove empty elements that

-  contribute no semantic information to the document. The following types

-  of nodes will be removed:

-</p>

-<ul><li>

-    Tags with no attributes and no content, and that are not empty

-    elements (remove <code>&lt;a&gt;&lt;/a&gt;</code> but not

-    <code>&lt;br /&gt;</code>), and

-  </li>

-  <li>

-    Tags with no content, except for:<ul>

-      <li>The <code>colgroup</code> element, or</li>

-      <li>

-        Elements with the <code>id</code> or <code>name</code> attribute,

-        when those attributes are permitted on those elements.

-      </li>

-    </ul></li>

-</ul>

-<p>

-  Please be very careful when using this functionality; while it may not

-  seem that empty elements contain useful information, they can alter the

-  layout of a document given appropriate styling. This directive is most

-  useful when you are processing machine-generated HTML, please avoid using

-  it on regular user HTML.

-</p>

-<p>

-  Elements that contain only whitespace will be treated as empty. Non-breaking

-  spaces, however, do not count as whitespace. See

-  %AutoFormat.RemoveEmpty.RemoveNbsp for alternate behavior.

-</p>

-<p>

-  This algorithm is not perfect; you may still notice some empty tags,

-  particularly if a node had elements, but those elements were later removed

-  because they were not permitted in that context, or tags that, after

-  being auto-closed by another tag, where empty. This is for safety reasons

-  to prevent clever code from breaking validation. The general rule of thumb:

-  if a tag looked empty on the way in, it will get removed; if HTML Purifier

-  made it empty, it will stay.

-

-<p>

-  If you would like users to be able to define external stylesheets, but

-  only allow them to specify CSS declarations for a specific node and

-  prevent them from fiddling with other elements, use this directive.

-  It accepts any valid CSS selector, and will prepend this to any

-  CSS declaration extracted from the document. For example, if this

-  directive is set to <code>#user-content</code> and a user uses the

-  selector <code>a:hover</code>, the final selector will be

-  <code>#user-content a:hover</code>.

-</p>

-<p>

-  The comma shorthand may be used; consider the above example, with

-  <code>#user-content, #user-content2</code>, the final selector will

-  be <code>#user-content a:hover, #user-content2 a:hover</code>.

-</p>

-<p>

-  <strong>Warning:</strong> It is possible for users to bypass this measure

-  using a naughty + selector. This is a bug in CSS Tidy 1.3, not HTML

-  Purifier, and I am working to get it fixed. Until then, HTML Purifier

-  performs a basic check to prevent this.

-<p>

-  This directive turns on the style block extraction filter, which removes

-  use by you, usually to be placed in an external stylesheet, or a

-  <strong>Warning:</strong> It is possible for a user to mount an

-  imagecrash attack using this CSS. Counter-measures are difficult;

-  it is not simply enough to limit the range of CSS lengths (using

-  relative lengths with many nesting levels allows for large values

-  to be attained without actually specifying them in the stylesheet),

-  and the flexible nature of selectors makes it difficult to selectively

-  disable lengths on image tags (HTML Purifier, however, does disable

-  CSS width and height in inline styling). There are probably two effective

-  counter measures: an explicit width and height set to auto in all

-  images in your document (unlikely) or the disabling of width and

-  height (somewhat reasonable). Whether or not these measures should be

-  used is left to the reader.

-    This is a preferred convenience directive that combines

-    Specify elements and attributes that are allowed using:

-    <code>element1[attr1|attr2],element2...</code>.  For example,

-    if you would like to only allow paragraphs and links, specify

-    <code>a[href],p</code>.  You can specify attributes that apply

-    You can also use newlines instead of commas to separate elements.

-</p>

-<p>

-    <strong>Warning</strong>:

-    All of the constraints on the component directives are still enforced.

-    The syntax is a <em>subset</em> of TinyMCE's <code>valid_elements</code>

-DEFAULT: NULL

-VERSION: 2.0.0

---DESCRIPTION--

-

-<p>

-    Unique identifier for a custom-built HTML definition. If you edit

-    the raw version of the HTMLDefinition, introducing changes that the

-    configuration object does not reflect, you must specify this variable.

-    If you change your custom edits, you should change this directive, or

-    clear your cache. Example:

-</p>

-<pre>

-$config = HTMLPurifier_Config::createDefault();

-$config->set('HTML', 'DefinitionID', '1');

-$def = $config->getHTMLDefinition();

-$def->addAttribute('a', 'tabindex', 'Number');

-</pre>

-<p>

-    In the above example, the configuration is still at the defaults, but

-    using the advanced API, an extra attribute has been added. The

-    configuration object normally has no way of knowing that this change

-    has taken place, so it needs an extra directive: %HTML.DefinitionID.

-    If someone else attempts to use the default configuration, these two

-    pieces of code will not clobber each other in the cache, since one has

-    an extra directive attached to it.

-</p>

-<p>

-    You <em>must</em> specify a value to this directive to use the

-    advanced API features.

-</p>

---DESCRIPTION--

-

-<p>

-    Revision identifier for your custom definition specified in

-    %HTML.DefinitionID.  This serves the same purpose: uniquely identifying

-    your custom definition, but this one does so in a chronological

-    context: revision 3 is more up-to-date then revision 2.  Thus, when

-    this gets incremented, the cache handling is smart enough to clean

-    up any older revisions of your definition as well as flush the

-    cache.

-VERSION: 3.1.0

---DESCRIPTION--

-<p>

-    While this directive is similar to %HTML.AllowedAttributes, for

-    forwards-compatibility with XML, this attribute has a different syntax. Instead of

-    <code>tag.attr</code>, use <code>tag@attr</code>. To disallow <code>href</code>

-    attributes in <code>a</code> tags, set this directive to

-    <code>a@href</code>. You can also disallow an attribute globally with

-    <code>attr</code> or <code>*@attr</code> (either syntax is fine; the latter

-    is provided for consistency with %HTML.AllowedAttributes).

-</p>

-<p>

-    <strong>Warning:</strong> This directive complements %HTML.ForbiddenElements,

-    accordingly, check

-    out that directive for a discussion of why you

-    should think twice before using this directive.

---DESCRIPTION--

-<p>

-    This was, perhaps, the most requested feature ever in HTML

-    other directive.

-</p>

-<p>

-    If possible, %HTML.Allowed is recommended over this directive, because it

-    can sometimes be difficult to tell whether or not you've forbidden all of

-    the behavior you would like to disallow. If you forbid <code>img</code>

-    with the expectation of preventing images on your site, you'll be in for

-    a nasty surprise when people start using the <code>background-image</code>

-    CSS property.

-TYPE: string/null

-VERSION: 1.3.0

-DEFAULT: NULL

---DESCRIPTION--

-

-<p>

-    Munges all browsable (usually http, https and ftp)

-    absolute URIs into another URI, usually a URI redirection service.

-    This directive accepts a URI, formatted with a <code>%s</code> where

-    the url-encoded original URI should be inserted (sample:

-    <code>http://www.google.com/url?q=%s</code>).

-</p>

-<p>

-    Uses for this directive:

-</p>

-<ul>

-    <li>

-        Prevent PageRank leaks, while being fairly transparent

-        to users (you may also want to add some client side JavaScript to

-        override the text in the statusbar). <strong>Notice</strong>:

-        Many security experts believe that this form of protection does not deter spam-bots.

-    </li>

-    <li>

-        Redirect users to a splash page telling them they are leaving your

-        website. While this is poor usability practice, it is often mandated

-        in corporate environments.

-    </li>

-</ul>

-<p>

-    Prior to HTML Purifier 3.1.1, this directive also enabled the munging

-    of browsable external resources, which could break things if your redirection

-    script was a splash page or used <code>meta</code> tags. To revert to

-    previous behavior, please use %URI.MungeResources.

-</p>

-<p>

-    You may want to also use %URI.MungeSecretKey along with this directive

-    in order to enforce what URIs your redirector script allows. Open

-    redirector scripts can be a security risk and negatively affect the

-    reputation of your domain name.

-</p>

-<p>

-    Starting with HTML Purifier 3.1.1, there is also these substitutions:

-</p>

-<table>

-    <thead>

-        <tr>

-            <th>Key</th>

-            <th>Description</th>

-            <th>Example <code>&lt;a href=""&gt;</code></th>

-        </tr>

-    </thead>

-    <tbody>

-        <tr>

-            <td>%r</td>

-            <td>1 - The URI embeds a resource<br />(blank) - The URI is merely a link</td>

-            <td></td>

-        </tr>

-        <tr>

-            <td>%n</td>

-            <td>The name of the tag this URI came from</td>

-            <td>a</td>

-        </tr>

-        <tr>

-            <td>%m</td>

-            <td>The name of the attribute this URI came from</td>

-            <td>href</td>

-        </tr>

-        <tr>

-            <td>%p</td>

-            <td>The name of the CSS property this URI came from, or blank if irrelevant</td>

-            <td></td>

-        </tr>

-    </tbody>

-</table>

-<p>

-    Admittedly, these letters are somewhat arbitrary; the only stipulation

-    was that they couldn't be a through f. r is for resource (I would have preferred

-    e, but you take what you can get), n is for name, m

-    was picked because it came after n (and I couldn't use a), p is for

-    property.

-<p>

-    This directive enables secure checksum generation along with %URI.Munge.

-    It should be set to a secure key that is not shared with anyone else.

-    The checksum can be placed in the URI using %t. Use of this checksum

-    affords an additional level of protection by allowing a redirector

-    to check if a URI has passed through HTML Purifier with this line:

-</p>

-

-<pre>$checksum === hash_hmac("sha256", $url, $secret_key)</pre>

-

-<p>

-    If the output is TRUE, the redirector script should accept the URI.

-</p>

-

-<p>

-    Please note that it would still be possible for an attacker to procure

-    secure hashes en-mass by abusing your website's Preview feature or the

-    like, but this service affords an additional level of protection

-    that should be combined with website blacklisting.

-</p>

-

-<p>

-    Remember this has no effect if %URI.Munge is not on.

-     *       a string would be somewhat expensive, so the function was modded to

-     *       directly operate on the string.  However, this discourages code

-     *       reuse, and the logic enumerated here would be useful for any

-     *       function that needs to be able to understand UTF-8 characters.

-     *       As of right now, only smart lossless character encoding converters

-     *       would need that, and I'm probably not going to implement them.

-     *       Once again, PHP 6 should solve all our problems.

-/**

- * Forgivingly lexes HTML (SGML-style) markup into tokens.

- *

- * A lexer parses a string of SGML-style markup and converts them into

- * corresponding tokens.  It doesn't check for well-formedness, although its

- * internal mechanism may make this automatic (such as the case of

- * HTMLPurifier_Lexer_DOMLex).  There are several implementations to choose

- * from.

- *

- * A lexer is HTML-oriented: it might work with XML, but it's not

- * recommended, as we adhere to a subset of the specification for optimization

- * reasons. This might change in the future. Also, most tokenizers are not

- * expected to handle DTDs or PIs.

- *

- * This class should not be directly instantiated, but you may use create() to

- * retrieve a default copy of the lexer.  Being a supertype, this class

- * does not actually define any implementation, but offers commonly used

- * convenience functions for subclasses.

- *

- * @note The unit tests will instantiate this class for testing purposes, as

- *       many of the utility functions require a class to be instantiated.

- *       This means that, even though this class is not runnable, it will

- *       not be declared abstract.

- *

- * @par

- *

- * @note

- * We use tokens rather than create a DOM representation because DOM would:

- *

- * @par

- *  -# Require more processing and memory to create,

- *  -# Is not streamable, and

- *  -# Has the entire document structure (html and body not needed).

- *

- * @par

- * However, DOM is helpful in that it makes it easy to move around nodes

- * without a lot of lookaheads to see when a tag is closed. This is a

- * limitation of the token system and some workarounds would be nice.

- * Website: http://sourceforge.net/projects/simplehtmldom/

- * Additional projects that may be used: http://sourceforge.net/projects/debugobject/

- * Acknowledge: Jose Solorzano (https://sourceforge.net/projects/php-html/)

- * Contributions by:

- *       Yousuke Kumakura (Attribute filters)

- *       Vadim Voituk (Negative indexes supports of "find" method)

- *       Antcs (Constructor with automatically load contents either text or file/url)

- *

- * all affected sections have comments starting with "PaperG"

- *

- * Paperg - Added case insensitive testing of the value of the selector.

- * Paperg - Added tag_start for the starting index of tags - NOTE: This works but not accurately.

- *  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,

- *  it will almost always be smaller by some amount.

- *  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.

- *  but for most purposes, it's a really good estimation.

- * Paperg - Added the forceTagsClosed to the dom constructor.  Forcing tags closed is great for malformed html, but it CAN lead to parsing errors.

- * Allow the user to tell us how much they trust the html.

- * 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.

- * This allows for us to find tags based on the text they contain.

- * Create find_ancestor_tag to see if a tag is - at any level - inside of another specific tag.

- * Paperg: added parse_charset so that we know about the character set of the source document.

- *  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

- *  last transfer or curl_exec, and we will parse that and use it in preference to any other method of charset detection.

- *

- * Found infinite loop in the case of broken html in restore_noise.  Rewrote to protect from that.

- * PaperG (John Schlick) Added get_display_size for "IMG" tags.
