3* JavaScript-like HTML DOM Element
4*
5* This class extends PHP's DOMElement to allow
6* users to get and set the innerHTML property of
7* HTML elements in the same way it's done in
8* JavaScript.
9*
10* Example usage:
11* @code
12* require_once 'JSLikeHTMLElement.php';
13* header('Content-Type: text/plain');
14* $doc = new DOMDocument();
15* $doc->registerNodeClass('DOMElement', 'JSLikeHTMLElement');
16* $doc->loadHTML('<div><p>Para 1</p><p>Para 2</p></div>');
17* $elem = $doc->getElementsByTagName('div')->item(0);
18*
19* // print innerHTML
20* echo $elem->innerHTML; // prints '<p>Para 1</p><p>Para 2</p>'
21* echo "\n\n";
22*
23* // set innerHTML
24* $elem->innerHTML = '<a href="http://fivefilters.org">FiveFilters.org</a>';
25* echo $elem->innerHTML; // prints '<a href="http://fivefilters.org">FiveFilters.org</a>'
26* echo "\n\n";
27*
28* // print document (with our changes)
29* echo $doc->saveXML();
30* @endcode

2/**
3* Arc90's Readability ported to PHP for FiveFilters.org
4* Based on readability.js version 1.7.1 (without multi-page support)
5* ------------------------------------------------------
6* Original URL: http://lab.arc90.com/experiments/readability/js/readability.js
7* Arc90's project URL: http://lab.arc90.com/experiments/readability/
8* JS Source: http://code.google.com/p/arc90labs-readability
9* Ported by: Keyvan Minoukadeh, http://www.keyvan.net
10* More information: http://fivefilters.org/content-only/
11* License: Apache License, Version 2.0
12* Requires: PHP5
13* Date: 2010-10-29
14*
15* Differences between the PHP port and the original
16* ------------------------------------------------------
17* Arc90's Readability is designed to run in the browser. It works on the DOM
18* tree (the parsed HTML) after the page's CSS styles have been applied and
19* Javascript code executed. This PHP port does not run inside a browser.
20* We use PHP's ability to parse HTML to build our DOM tree, but we cannot
21* rely on CSS or Javascript support. As such, the results will not always
22* match Arc90's Readability. (For example, if a web page contains CSS style
23* rules or Javascript code which hide certain HTML elements from display,
24* Arc90's Readability will dismiss those from consideration but our PHP port,
25* unable to understand CSS or Javascript, will not know any better.)
26*
27* Another significant difference is that the aim of Arc90's Readability is
28* to re-present the main content block of a given web page so users can
29* read it more easily in their browsers. Correct identification, clean up,
30* and separation of the content block is only a part of this process.
31* This PHP port is only concerned with this part, it does not include code
32* that relates to presentation in the browser - Arc90 already do
33* that extremely well, and for PDF output there's FiveFilters.org's
34* PDF Newspaper: http://fivefilters.org/pdf-newspaper/.
35*
36* Finally, this class contains methods that might be useful for developers
37* working on HTML document fragments. So without deviating too much from
38* the original code (which I don't want to do because it makes debugging
39* and updating more difficult), I've tried to make it a little more
40* developer friendly. You should be able to use the methods here on
41* existing DOMElement objects without passing an entire HTML document to
42* be parsed.
43*/
44
45// This class allows us to do JavaScript like assignements to innerHTML
46require_once(dirname(__FILE__).'/JSLikeHTMLElement.php');
47
48// Alternative usage (for testing only!)
49// uncomment the lins below and call Readability.php in your browser
50// passing it the URL of the page you'd like content from, e.g.:
51// Readability.php?url=http://medialens.org/alerts/09/090615_the_guardian_climate.php
