The need for an HTML5 parser in PHP is clear. This project initially
began with the seemingly abandoned html5lib
project original source.
But after some initial refactoring work, we began a new parser.
Install HTML5-PHP using composer.
To install, add masterminds/html5
to your composer.json
file:
{
"require" : {
"masterminds/html5": "2.*"
},
}
(You may substitute 2.*
for a more specific release tag, of
course.)
From there, use the composer install
or composer update
commands to
install.
HTML5-PHP has a high-level API and a low-level API.
Here is how you use the high-level HTML5
library API:
<?php
// Assuming you installed from Composer:
require "vendor/autoload.php";
use Masterminds\HTML5;
// An example HTML document:
$html = <<< 'HERE'
<html>
<head>
<title>TEST</title>
</head>
<body id='foo'>
<h1>Hello World</h1>
<p>This is a test of the HTML5 parser.</p>
</body>
</html>
HERE;
// Parse the document. $dom is a DOMDocument.
$html5 = new HTML5();
$dom = $html5->loadHTML($html);
// Render it as HTML5:
print $html5->saveHTML($dom);
// Or save it to a file:
$html5->save($dom, 'out.html');
?>
The $dom
created by the parser is a full DOMDocument
object. And the
save()
and saveHTML()
methods will take any DOMDocument.
It is possible to pass in an array of configuration options when loading an HTML5 document.
// An associative array of options
$options = array(
'option_name' => 'option_value',
);
// Provide the options to the constructor
$html5 = new HTML5($options);
$dom = $html5->loadHTML($html);
The following options are supported:
encode_entities
(boolean): Indicates that the serializer should aggressively
encode characters as entities. Without this, it only encodes the bare
minimum.disable_html_ns
(boolean): Prevents the parser from automatically
assigning the HTML5 namespace to the DOM document. This is for
non-namespace aware DOM tools.target_document
(\DOMDocument): A DOM document that will be used as the
destination for the parsed nodes.implicit_namespaces
(array): An assoc array of namespaces that should be
used by the parser. Name is tag prefix, value is NS URI.This library provides the following low-level APIs that you can use to create more customized HTML5 tools:
InputStream
abstraction that can work with different kinds of
input source (not just files and strings).The unit tests exercise each piece of the API, and every public function is well-documented.
The parser is designed as follows:
InputStream
portion handles direct I/O.Scanner
handles scanning on behalf of the parser.Tokenizer
requests data off of the scanner, parses it, clasifies
it, and sends it to an EventHandler
. It is a recursive descent parser.EventHandler
receives notifications and data for each specific
semantic event that occurs during tokenization.DOMBuilder
is an EventHandler
that listens for tokenizing
events and builds a document tree (DOMDocument
) based on the events.The serializer takes a data structure (the DOMDocument
) and transforms
it into a character representation -- an HTML5 document.
The serializer is broken into three parts:
OutputRules
contain the rules to turn DOM elements into strings. The
rules are an implementation of the interface RulesInterface
allowing for
different rule sets to be used.Traverser
, which is a special-purpose tree walker. It visits
each node node in the tree and uses the OutputRules
to transform the node
into a string.HTML5
manages the Traverser
and stores the resultant data
in the correct place.The serializer (save()
, saveHTML()
) follows the
section 8.9 of the HTML 5.0 spec.
So tags are serialized according to these rules:
Please check the issue queue for a full list, but the following are issues known issues that are not presently on the roadmap:
:
has no special
meaning.
By default the parser does not support XML style namespaces via :
;
to enable the XML namespaces see the XML Namespaces section##XML Namespaces
To use XML style namespaces you have to configure well the main HTML5
instance.
use Masterminds\HTML5;
$html = new HTML5(array(
"xmlNamespaces" => true
));
$dom = $html->loadHTML('<t:tag xmlns:t="http://www.example.com"/>');
$dom->documentElement->namespaceURI; // http://www.example.com
You can also add some default prefixes that will not require the namespace declaration, but it's elements will be namespaced.
use Masterminds\HTML5;
$html = new HTML5(array(
"implicitNamespaces"=>array(
"t"=>"http://www.example.com"
)
));
$dom = $html->loadHTML('<t:tag/>');
$dom->documentElement->namespaceURI; // http://www.example.com
The dedicated (and patient) contributors of patches small and large, who have already made this library better.See the CREDITS file for a list of contributors.
We owe a huge debt of gratitude to the original authors of html5lib.
While not much of the orignal parser remains, we learned a lot from reading the html5lib library. And some pieces remain here. In particular, much of the UTF-8 and Unicode handling is derived from the html5lib project.
