This is a powerful feature that uses a JS-like tag Selector to identify the DOM

The Ganon library gives access to html/xml documents in a very simple object oriented the. It eases modifying the DOM and makes finding elements easy with css3-like queries.

Ganon Use Example:

// Parse The Google Code website into a DOM $html = file_get_dom (' http://code.google.com/');

Access
Accessing elements is made easy through the Css3-like selectors and the object model.

//Find all the paragraph tags with a class attribute and print the//value of the class attribute foreach($html(' P[class] ') as $element) {   Echo $element-class, "<br>\n"; }  //Find the first div with ID "Gc-header" and print the plain text of//The parent element (plain text means no HTML ta GS, just the text) Echo $html(' Div#gc-header ', 0)->parent->Getplaintext (); //Find out how many tags there is which is "ns:tag" or "div", but not//"a" and does not have a class attribute Echo Count($html(' (Ns|tag, div +!a) [!class] ');?>

Modification
Elements can easily modified after you ' ve found them.

//Find All paragraph tags which is nested inside a div tag, change//their ID attribute and print the new HTML Co De     foreach($html(' Div p ') as $index=$element) {       $element->id = "id$index"; }     Echo $html; //Center all links inside a document which start with "HTTP +/"//and print out the new HTML     foreach($html(' A[href ^= '/'/'] ') as $element) {       $element->wrap (' Center '); }     Echo $html; //Find all odd indexed "TD" elements and change the HTML to make them links     foreach($html(' Table td:odd ') as $element) {       $element->setinnertext (' <a href= ' # ' > '.$element->getplaintext (). ' </a> '); }     Echo $html;

Beautify
Ganon can also help you beautify your code and format it properly.

// beautify the old HTML code and print out the new, formatted code     Dom_format ($htmlarray(' attributes_case ' = case_lower));      Echo $html;
