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)
toArray()
Returns underlying DOM structure as an array.
Values are attributes, text content under #text
key and child elements under numeric keys
toXml()
Returns HTML string
getDom() toDom()
Returns DOMDocument. Given true as the first argument - can also return DOMNodeList or DOMElement
