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+, _(*2)

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);, _(*6)

get($cssSelector)

$cssSelector elements have the following format: tagName[attribute=value]#elementId.className:pseudoSelector(expression), _(*7)

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

toArray()

Returns underlying DOM structure as an array.
Values are attributes, text content under #text key and child elements under numeric keys, _(*8)

toXml()

Returns HTML string, _(*9)

getDom() toDom()

Returns DOMDocument. Given true as the first argument - can also return DOMNodeList or DOMElement, _(*10)

Iteration over found elements

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