README

A Simple HTML DOM parser written in PHP let you manipulate HTML in a easy way with selectors just like CSS or jQuery.

This is modern version of Simple HTML DOM. You can install by using Composer and import to your project as a package.

Features

Parse and modify HTML document.
Find tags (elements) on HTML with selectors just like jQuery.
Extract contents from HTML in a single line.
Export elements or a special node to a single file.
Supports HTML document with invalid structure.

Installation

You can use Composer to install this package to your project by running following command:

composer require zenthangplus/html-dom-parser

The minimum PHP version requirement is 5.6. If you are using PHP < 5.6, please use the original version.

Usage

The following example is the simple usage of this package:

<?php
$dom = \HTMLDomParser\DomFactory::load('<div class="container"><div class="anchor"><a href="#">Test</a></div></div>');
$a = $dom->findOne('.container a');
echo $a->text();
// Output: Test

DOM

Dom is the root Node of the HTML document.

You can load DOM from string or file.

<?php
$dom = \HTMLDomParser\DomFactory::load('<div>Test</div>');

<?php
$dom = \HTMLDomParser\DomFactory::loadFile('document.html');

NODE

Node is simply an HTML element that described as an object.

You can also load any Node (similar to Dom):

<?php
$node = \HTMLDomParser\NodeFactory::load('<div><a href="#">Test</a></div>');

<?php
$node = \HTMLDomParser\NodeFactory::loadFile('document.html');

Traversing the DOM

By using selectors like jQuery or CSS, you can traverse easy in the Dom or even in a Node.

Example:

<?php
$dom = \HTMLDomParser\DomFactory::loadFile('document.html');
$dom->find('div');
$dom->find('#container');
$dom->find('#container .content ul>li a.external-link');
$dom->find('#container .content ul>li a[data-id=link-1]');

Similar to Dom, a Node also traversable:

<?php
$dom = \HTMLDomParser\DomFactory::loadFile('document.html');
$node = $dom->findOne('#container .content ul>li');
$anchorNode = $node->findOne('a.external-link');

// Even traverse in a separate Node
$node = \HTMLDomParser\NodeFactory::load('<ul class="list"><li>Item 1</li><li>Item 2</li></ul>');
$node->find('ul.list li');

List of supported selectors:

Selector example	Description
`div`	Find elements with the `div` tag
`#container`	Find elements with the `container` id
`.wrapper`	Find elements with the `wrapper` class
`[data-id]`	Find elements with the `data-id` attribute
`[data-id=12]`	Find elements with the attribute `data-id=12`
`a[data-id=12]`	Find anchor tags with the attribute `data-id=12`
`*[class]`	Find all elements with `class` attribute
`a, img`	Find all anchors and images
`a[title], img[title]`	Find all anchors and images with the `title` attribute
`#container ul`	By using `space` between selectors, you can find nested elements
`#container>ul`	By using `>` between selectors, you can find the closest children
`#container, #side`	By using `,` between selectors, you can find elements by multiple selectors in one query
`#container div.content ul>li, #side div[role=main] ul li`	You can combine selectors in one query
