README

Fast (HTML DOM) parser written in PHP.

Important note

This is a fork of the project https://code.google.com/p/ganon/

Installation

Via composer (https://packagist.org/packages/wangoviridans/ganon)

{
    "require": {
        "wangoviridans/ganon": "dev-master"
    }
}

Or just clone and put somewhere inside your project folder.

$ cd myapp/vendor
$ git clone git://github.com/wangoviridans/ganon.git

Usage

Including

<?php
require 'vendor/autoload.php';
use Wangoviridans\Ganon;

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

After including Ganon and loading the DOM, it is time to get started.

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 tags, just the text)
 echo $html('div#gc-header', 0)->parent->getPlainText();


 // Find out how many tags there are which are "ns:tag" or "div", but not
 // "a" and do not have a class attribute
 echo count($html('(ns|tag, div + !a)[!class]');

Modification

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

 // Find all paragraph tags which are nested inside a div tag, change
 // their ID attribute and print the new HTML code
 foreach($html('div p') as $index => $element) {
   $element->id = "id$index";
 }
 echo $html;


 // Center all the links inside a document which start with "http://"
 // and print out the new HTML
 foreach($html('a[href ^= "http://"]') 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($html, array('attributes_case' => CASE_LOWER));
echo $html;
