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 | ||
