Attention: New version can break compatibility, in that case use previous version under the v1.0 branch or tag which supports even php 5.4+

\nokogiri class is left for compatibility

HTML parser

This library is a fast HTML parser, which can work with invalid code (errors are ignored).
Under the hood is used LibXML.
As the input you can use HTML string in UTF-8 encoding or DOMDocument.
For the querying elements CSS selectors are used, which are transformed to XPath expressions internally.

Usage

Loading HTML

HTML errors are ignored * From HTML string

$saw = new \nokogiri($html);

$saw = \nokogiri::fromHtml($html);

* From DOM elements

$saw = new \nokogiri($dom);

$saw = \nokogiri::fromDom($dom);

get($cssSelector)

$cssSelector elements have the following format:

tagName[attribute=value]#elementId.className:pseudoSelector(expression)

php
$saw->get('div > a[rel=bookmark]')->toArray();

toArray()

Returns underlying DOM structure as an array.
Values are attributes, text content under

#text

toXml()

Returns HTML string

getDom() toDom()

Returns DOMDocument. Given true as the first argument - can also return DOMNodeList or DOMElement

Iteration over found elements

foreach ($saw->get('#sidebar a.topic') as $link){
    var_dump($link['#text']);
}
