A simple library for management the DOM (XML, HTML) document.

Project repository: https://github.com/cs-eliseev/dom-manager

DEMO

use cse\DOMManager\DomManager;
...
$content = file_get_contents('https://www.w3schools.com/xml/simple.xml');
$easyLoader = new DomManager();
$node = $easyLoader->parse($content);
$name = $node->find('name')->first()->text(); // Belgian Waffles

Usage

The following demonstrates how to use the functions of this library in a PHP application.

Init

The DomManager instance convert data into a structure for manipulating the DOM tree.

Converting XML structure:

use cse\DOMManager\IDomManager;
...
$easyLoader = new IDomManager();
$nodes = $easyLoader->parse('<div><br/><br/></div>'); // Nodes entity

Converting HTML structure via DOMDocument:

use cse\DOMManager\DomManager;
...
$domDocument = new DOMDocument('1.0', 'UTF-8');
$domDocument->loadHTML('<div><br><br></div>');
$easyLoader = new DomManager();
$nodes = $easyLoader->parse($domDocument); // Nodes entity

Converting DOMNodeList:

use cse\DOMManager\DomManager;
...
$domDocument = new DOMDocument('1.0', 'UTF-8');
$domDocument->loadXML('<div><br/><br/></div>');

$easyLoader = new DomManager();
$nodes = $easyLoader->parse($domDocument->getElementsByTagName('br')); // Nodes entity

Converting DOMNode:

use cse\DOMManager\DomManager;
...
$domDocument = new DOMDocument('1.0', 'UTF-8');
$domDocument->loadXML('<div><br/><br/></div>');

$easyLoader = new DomManager();
$nodes = $easyLoader->parse($domDocument->getElementsByTagName('br')->item(1)); // Nodes entity

An instance of the Nodes represents a list of DOMNode objects, can be manipulation.

Replacing children by node name:

/** @var \cse\DOMManager\Nodes\Nodes $nodes */
$nodes->find('h1')->replaceChildes('<section><div>Header</div>Content</section>', 'i');

Result:

<h1><section><div>Header</div>Content</section><span>Header</span>-subheader</h1>

Remove chides

Remove childes node.

Removing all childes:

/** @var \cse\DOMManager\Nodes\Nodes $nodes */
$nodes->find('h1')->removeChildes();

Result:

<h1>-subheader</h1>

Removing descendants by node name:

/** @var \cse\DOMManager\Nodes\Nodes $nodes */
$nodes->find('h1')->removeChildes('i');

Result:

<h1><span>Header</span>-subheader</h1>

DOMNode list

Returns a list of DOMNode elements.

List:

/** @var \cse\DOMManager\Nodes\Nodes $nodes */
$nodes->find('p')->toArray();

Result:

[
    class DOMElement {},
    class DOMElement {},
    class DOMElement {},
    class DOMElement {}
]

NodeList

Return NodeList.

NodeList:

/** @var \cse\DOMManager\Nodes\Nodes $nodes */
$nodes->find('p')->toList();

Result:

class NodeList {}

Content

Returns the markup of an element, including its content.

Get the content of the current element:

/** @var \cse\DOMManager\Nodes\Nodes $nodes */
$nodes->find('h1')->toString();

Result:

<h1><i class="icon"/><span>Header</span>-subheader</h1>

Find and get the content of the element:

/** @var \cse\DOMManager\Nodes\Nodes $nodes */
$nodes->toString('h1');

Result:

<h1><i class="icon"/><span>Header</span>-subheader</h1>

Find by XPath and get the content of the element:

/** @var \cse\DOMManager\Nodes\Nodes $nodes */
$nodes->toString('//div/p');

Result:

<p><span class="text">First text</span></p>
<p>Last text</p>
<p>First description</p>
<p><span>Last description</span></p>a

Foreach elements

Calls a callback function for each item.

/** @var \cse\DOMManager\Nodes\Nodes $nodes */
$elem = $nodes->find('div');
$elem->each(function (\cse\DOMManager\Nodes\Nodes $item) {
    if ($item->hasAttr('class')) {
        $item->removeAttr('class');
    }
    $item->addText('this div element');
});
echo $elem->root()->content();

Result:

<main class="main" role="main"><div><div><h1><i class="icon"/><span>Header</span>-subheader</h1><img src="content_img.jpg" alt="content img"/><p><span class="text">First text</span></p>this div element</div><br/><p>Last text</p>this div element</div><div role="contentinfo"><p>First description</p><br/><em>Middle description</em><p><span>Last description</span></p>this div element</div></main>

Testing & Code Coverage

PHPUnit is used for unit testing. Unit tests ensure that class and methods does exactly what it is meant to do.

General PHPUnit documentation can be found at https://phpunit.de/documentation.html.

To run the PHPUnit unit tests, execute:

phpunit PATH/TO/PROJECT/tests/

If you want code coverage reports, use the following:

phpunit --coverage-html ./report PATH/TO/PROJECT/tests/

Used PHPUnit default config:

phpunit --configuration PATH/TO/PROJECT/phpunit.xml
