pop-dom

The popphp/pop-dom component is a component for managing and building DOM objects. It provides an easy-to-use API to assist in creating XML and HTML documents, while creating and managing the documents’ elements and attributes.

Installation

Install it directly into your project:

composer require popphp/pop-dom

Or, include it in your composer.json file:

{
    "require": {
        "popphp/pop-dom": "3.0.*",
    }
}

Basic Use

The popphp/pop-dom component is for generating and rendering DOM documents and elements. With it, you can easily create document nodes and their children and have control over node content and attributes.

Creating a Simple Node

use Pop\Dom\Child;

$div = new Child('div');
$h1  = new Child('h1', 'This is a header');
$p   = new Child('p');
$p->setNodeValue('This is a paragraph.');

$div->addChildren([$h1, $p]);

echo $div;

The above code produces the following HTML:

<div>
    <h1>This is a header</h1>
    <p class="paragraph">This is a paragraph.</p>
</div>

Build a DOM Document

Putting all of it together, you can build a full DOM document like this:

// Title element
$title = new Child('title', 'This is the title');

// Meta tag
$meta = new Child('meta');
$meta->setAttributes([
    'http-equiv' => 'Content-Type',
    'content'    => 'text/html; charset=utf-8'
]);

// Head element
$head = new Child('head');
$head->addChildren([$title, $meta]);

// Some body elements
$h1 = new Child('h1', 'This is a header');
$p  = new Child('p', 'This is a paragraph.');

$div = new Child('div');
$div->setAttribute('id', 'content');
$div->addChildren([$h1, $p]);

// Body element
$body = new Child('body');
$body->addChild($div);

// Html element
$html = new Child('html');
$html->addChildren([$head, $body]);

// Create and render the DOM document with HTTP headers
$doc = new Document(Document::HTML, $html);
echo $doc;

Which produces the following HTML:

<!DOCTYPE html>
<html>
    <head>
        <title>This is the title</title>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    </head>
    <body>
        <div id="content">
            <h1>This is a header</h1>
            <p>This is a paragraph.</p>
        </div>
    </body>
</html>
