Just for reference, as of this writing, this function does not support importing multiple stylesheets. The following will output only the stylesheet transformation of the second imported sheet:



<?php



# LOAD XML FILE

$XML = new DOMDocument();

$XML->load( 'data.xml' );



# START XSLT

$xslt = new XSLTProcessor();



# IMPORT STYLESHEET 1

$XSL = new DOMDocument();

$XSL->load( 'template1.xsl' );

$xslt->importStylesheet( $XSL );



#IMPORT STYLESHEET 2

$XSL = new DOMDocument();

$XSL->load( 'template2.xsl' );

$xslt->importStylesheet( $XSL );



#PRINT

print $xslt->transformToXML( $XML );

?>



This wasn't documented and quite dissapointing.

For those who wants to use external documents, it is important not to use the DomDocument::loadXML because the processor will not have the path to look for other files

 

So if you want to transform some xml with a pre-generated stylesheet $f:



<?php

$f = 'somestylesheet.xsl';

$xsl = DomDocument::loadXML(file_get_contents($f));

?>



document('other.xml') will not work with relative path and <?php $xsl = DomDocument::load($f); ?> will!

This is not a problem. You may set DOMDocument's documentURI property. 

Something like this 



<?php

$xsl = new DOMDocument('1.0','UTF-8');

     

$xsl->loadXML(file_get_contents('/foo/bar/somefile.xsl');

$xsl->documentURI = '/foo/bar/somefile.xsl';



$xslProc = new XSLTProcessor();

$xslProc->importStylesheet($xsl);

?>



and document('other.xsl') will work fine!

PHP5 xsl processor has a different behaviour than PHP4's one with CDATA sections. (see http://bugs.php.net/bug.php?id=29837)

Loaded XSL sheet CDATA sections does not allow, by default, output-escaping handling (everything in the CDATA is escaped by default).



So in this case you can't build your XSL Dom the usual way:

    $xsldom = DomDocument::loadXML(file_get_contents('sheet.xsl'));



and must go through this one (allowing LIBXML_NOCDATA parameter):

    $xsldom = new DomDocument;

    $xsldom->load('sheet.xsl', LIBXML_NOCDATA);



Then the CDATA output-escaping behaviour will be correct.

To make your import dynamic, try this code:



<?php

$dom = new DOMDocument();

$dom->load('main.xsl');

$xpath = new DomXPath($dom);

$importnode= $questionsXsl->createElement('xsl:include');

$attr= $questionsXsl->createAttribute('href');

$attr->value = 'import.xsl';

$importnode->appendChild($attr);

$dom->documentElement->insertBefore($importnode,$ref);

$dom->loadXml($dom->saveXml());

?>



this code basically loads the main stylesheet, prepend the import xsl code then reload as xml string so the imported stylesheet will be loaded at dom.
