PHP & XSL; problem with xsl:choose

[loftinsualtion]

Hello,

I have some xml, and have made some xsl to display the data in some lovely tables. This works beautifully on my development set-up (Windows, Apache 2.2.13, PHP 5.2.11), but fails on my hosted server (Linux, Apache 2.2.13, PHP 5.2.12). I'm using the XSL extension in PHP and the following basic code:

$xslDoc = new DOMDocument();
$xslDoc->load('transform.xsl');

$xmlDoc = new DOMDocument();
$xmlDoc->load('transformee.xml');

$proc = new XSLTProcessor();
$proc->importStylesheet($xslDoc);

$html = $proc->transformToXML($xmlDoc); 

 

Having done some investigation it is the xsl:choose statements in the xsl that cause the failure (yielding internal server error) on the hosted server. Removing these, the rest works fine - it is just the xsl:choose parts that cause transformToXML to fail (but interestingly not returning false).

 

Just wondering if anyone may know what is going on here? Does it sound like a configuration issue for my hosting supplier?

 

Thanks very much.
