Here's one way you could do it, by calling into a PHP function from XSLT:

function parseHTMLString($html)
{
    $doc = new DOMDocument();
    $doc->loadHTML($html);
    return $doc;
}

$xml = <<
    
        
    

EOB;

$xsl = <<

 
   
 

 
   

 

EOB;

$xmldoc = new DOMDocument();
$xmldoc->loadXML($xml);

$xsldoc = new DOMDocument();
$xsldoc->loadXML($xsl);

$proc = new XSLTProcessor();
$proc->registerPHPFunctions('parseHTMLString');
$proc->importStyleSheet($xsldoc);
echo $proc->transformToXML($xmldoc);
