Update: html5lib (bottom of question) seems to get close, I just need to improve my understanding of how it's used.
I am attempting to find an HTML5-compatible DOM parser for PHP 5.3. In particular, I need to access the following HTML-like CDATA within a script tag:
<script type="text/x-jquery-tmpl" id="foo">
<table><tr><td>${name}</td></tr></table>
</script>
Most parsers will end parsing prematurely because HTML 4.01 ends script tag parsing when it finds ETAGO (</) inside a <script> tag. However, HTML5 allows for </ before </script>. All of the parsers I have tried so far have either failed, or they are so poorly documented that I haven't figured out if they work or not.
My requirements:
- Real parser, not regex hacks.
- Ability to load full pages or HTML fragments.
- Ability to pull script contents back out, selecting by the tag's id attribute.
Some failing parsers:
DOMDocument
Source:
<?php
header('Content-type: text/plain');
$d = new DOMDocument;
$d->loadHTML('<script id="foo"><td>bar</td></script>');
echo $d->saveHTML();
Output:
Warning: DOMDocument::loadHTML(): Unexpected end tag : td in Entity, line: 1 in /home/adam/public_html/2010/10/26/dom.php on line 5
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<html><head><script id="foo"><td>bar</script></head></html>
FluentDOM
Source:
<?php
header('Content-type: text/plain');
require_once 'FluentDOM/src/FluentDOM.php';
$html = "<html><head></head><body><script id='foo'><td></td></script></body></html>";
echo FluentDOM($html, 'text/html');
Output:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<html><head></head><body><script id="foo"><td></script></body></html>
phpQuery
Source:
<?php
header('Content-type: text/plain');
require_once 'phpQuery.php';
phpQuery::newDocumentHTML(<<<EOF
<script type="text/x-jquery-tmpl" id="foo">
<td>test</td>
</script>
EOF
);
echo (string)pq('#foo');
Output:
<script type="text/x-jquery-tmpl" id="foo">
<td>test
</script>
html5lib
Possibly promising. Can I get at the contents of the script#foo tag?
Source:
<?php
header('Content-type: text/plain');
include 'HTML5/Parser.php';
$html = "<!DOCTYPE html><html><head></head><body><script id='foo'><td></td></script></body></html>";
$d = HTML5_Parser::parse($html);
echo $d->saveHTML();
Output:
<html><head></head><body><script id="foo"><td></td></script></body></html>
