* JavaScript-like HTML DOM Element
|

*
|

* This class extends PHP's DOMElement to allow
|
||||
* users to get and set the innerHTML property of
|
||||
* HTML elements in the same way it's done in
|
||||
* JavaScript.
|
||||
*
|
||||
* Example usage:
|
||||
* @code
|
||||
* require_once 'JSLikeHTMLElement.php';
|
||||
* header('Content-Type: text/plain');
|
||||
* $doc = new DOMDocument();
|
||||
* $doc->registerNodeClass('DOMElement', 'JSLikeHTMLElement');
|
||||
* $doc->loadHTML('<div><p>Para 1</p><p>Para 2</p></div>');
|
||||
* $elem = $doc->getElementsByTagName('div')->item(0);
|
||||
*
|
||||
* // print innerHTML
|
||||
* echo $elem->innerHTML; // prints '<p>Para 1</p><p>Para 2</p>'
|
||||
* echo "\n\n";
|
||||
*
|
||||
* // set innerHTML
|
||||
* $elem->innerHTML = '<a href="http://fivefilters.org">FiveFilters.org</a>';
|
||||
* echo $elem->innerHTML; // prints '<a href="http://fivefilters.org">FiveFilters.org</a>'
|
||||
* echo "\n\n";
|
||||
*
|
||||
* // print document (with our changes)
|
||||
* echo $doc->saveXML();
|
||||
* @endcode
