Html wrapper in php

README

PHP DOM Wrapper is a simple DOM wrapper library to manipulate and traverse HTML documents. Based around jQuery’s manipulation and traversal methods, largely mimicking the behaviour of it’s jQuery counterparts.

Manipulation

addClass

$doc = (new Document())->html('
first paragraph
second paragraph
'); $doc->find('p')->addClass('text-center');

follow

self follow(string|NodeList|\DOMNode|callable $input) 

Insert the argument as a sibling directly after each of the nodes operated on.

substituteWith

self substituteWith(string|NodeList|\DOMNode|callable $input) 

Example

text

string|self text([string|NodeList|\DOMNode|callable $input = null]) 

Example

unwrap

Unwrap each current node by removing its parent, replacing the parent with its children (i.e. the current node and its siblings).

Note that each node is operated on separately, so when you call unwrap() on a NodeList containing two siblings, two parents will be removed.

Example

$doc = (new Document())->html('
'); $doc->find('#first')->unwrap();

div id pl-s">first">div> div id pl-s">second">div>

wrap

self wrap(string|NodeList|\DOMNode|callable $input) 

Wrap the current node or nodes in the given structure.

The wrapping structure can be nested, but should only contain one node on each level (any extra siblings are removed). The outermost node replaces the node operated on, while the node operated on is put into the innermost node.

If called on a NodeList , each of nodes in the list will be separately wrapped. When such a list contains multiple nodes, the argument to wrap() cannot be a NodeList or \DOMNode , since those can be used to wrap a node only once. A string or callable returning a string or a unique NodeList or \DomNode every time can be used in this case.

When a callable is passed, it is called once for each node operated on, passing that node and its index. The callable should return either a string, or a unique NodeList or \DOMNode ever time it is called.

Note that this returns the original node like all other methods, not the (new) node(s) wrapped around it.

Example

$doc = (new Document())->html('foobar'); $doc->find-> ('span')->wrap('
');

div>p>span>foospan>p>div> div>p>span>barspan>p>div>

wrapAll

self wrapAll(string|NodeList|\DOMNode|callable $input) 

Like wrap(), but when operating on multiple nodes, all of them will be wrapped together in a single instance of the given structure, rather than each of them individually.

Note that the wrapping structure replaces the first node operated on, so if the other nodes operated on are not siblings of the first, they will be moved inside the document.

Example

$doc = (new Document())->html('foobar'); $doc->find-> ('span')->wrapAll('
');

div>p> span>foospan> span>barspan> p>div>

wrapInner

self wrapInner(string|NodeList|\DOMNode|callable $input) 

Like wrap(), but rather than wrapping the nodes that are being operated on, this wraps their contents.

Example

$doc = (new Document())->html('foobar'); $doc->find('span')->wrapInner('');

span>b>i>fooi>b>span> span>b>i>bari>b>span>
