html5lib - php flavour
32

4-
This is an implementation of the HTML5 specification for PHP. More friendly
5-
details forthcoming, but here are some notes:
3+
This is an implementation of the tokenization and tree-building parts
4+
of the HTML5 specification in PHP. Potential uses of this library
5+
can be found in web-scrapers and HTML filters.
6+
7+
Warning: This is a pre-alpha release, and as such, certain parts of
8+
this code are not up-to-snuff (e.g. error reporting and performance).
9+
However, the code is very close to spec and passes 100% of tests
10+
not related to parse errors. Nevertheless, expect to have to update
11+
your code on the next upgrade.
12+
13+
14+
Usage notes:
15+
16+
<?php
17+
require_once '/path/to/HTML5/Parser.php';
18+
$dom = HTML5_Parser::parse('<html><body>...');
19+
$nodelist = HTML5_Parser::parseFragment('<b>Boo</b><br>');
20+
$nodelist = HTML5_Parser::parseFragment('<td>Bar</td>', 'table');
21+
22+
23+
Documentation:
24+
25+
HTML5_Parser::parse($text)
26+
$text : HTML to parse
27+
return : DOMDocument of parsed document

Developer notes:

* To setup unit tests, you need to add a small stub file test-settings.php
838
that contains $simpletest_location = 'path/to/simpletest/'; This needs to
939
be version 1.1 (or, until that is released, SVN trunk) of SimpleTest.

* We don't want to ultimately use PHP's DOM because it is not tolerant
1242
of certain types of errors that HTML 5 allows (for example, an element
13-
"foo@bar"). But for now, we will, since it's much easier.
43+
"foo@bar"). But the current implementation uses it, since it's easy.
44+
Eventually, this html5lib implementation will get a version of SimpleTree;
45+
and may possibly start using that by default.
