Hi Jirka, all,


With respect to the problem I explained at Lyon regarding PHP and the use of
XHTML namespaces, I’ve been doing a little research and I found this bug:
loadHTML doesn't use XHTML namespace https://bugs.php.net/bug.php?id=38538  


The problem is that when you try to load an HTML with the functions
loadHTMLFile  or loadHTML, even if you register the namespace, when doing
the xpath query with the NS h, it doesn’t work. So e.g. for the html
translate example number 1 of the Test Suite, a simple code like the
following won’t work.




$xpath = new DOMXPath($dom);

$xpath->registerNamespace('h', 'http://www.w3.org/1999/xhtml');

$query = '//h:code';

$nodes = $xpath->query($query);


If I use $dom->load(translate1html.html); instead of loadHTMLFile, it works
but unlike loading HTML, XML has to be well-formed to load. So with lines
like <meta charset=utf-8> the parser won’t work unless it’s well-formed
<meta charset="utf-8"/>


I don’t know if somebody has encountered the same problem, in that case, is
there a solution? I can’t find any apart from removing the namespaces when
doing the xpath query. I read also that a solution might be turn the HTML
into XHTML with the PHP Tidy extension, but I’m not sure.


Any help will be welcome. Thanks!
