Hi Guys, Well i;ve been slaving on with my PHP XML endeavors and i'm loving it, just finishing the meaty parts of my XSLT for dummies book too. I have a question which asks "is it possible?". Using XSLT I can collect specific parts of my XML using something sexy like <xsl:template match="umbungo">. Lets say however, that I need to use XSLT, but I would want the user to select which element they request. In other words, they are given a form with options and that form can manipulate the .XSL file. Now I know it could be done in a lengthly manner by just opening the XSL file and manipulating it like fopen or something like that, but is there a way to somehow embed the contents of the xml into the php code (like using <<< EOF for html), and being able to substitute the template match string for a variable ? Any ideas ? Thanks Gamesmaster, Matt

A bit off-topic (since XSLT is not PHP...) but here goes. First I need to clarify what you are doing - <xsl:template match="umbongo"> ... </xsl:template> defines the template portion, and that is pretty immutable. At some point you must have in your XSLT something like <xsl:apply-templates select="umbongo"/> This is the bit you can play with: so: <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="xml" encoding="UTF-8" /> <!-- or whatever --> <!-- Pass in a parameter to the XSL to define which thing we want to match --> <xsl:parameter name='matchMe'/> <!-- Define templates for all the things we might want to match --> <xsl:template match='umbongo'><xsl:apply-templates/></xsl:template> <xsl:template match='fivealive'><xsl:apply-templates/></xsl:template> <!-- etc. --> <!-- now the clever bit --> <xsl:template match='/'>

       <xsl:apply-templates select='//*[name()=$matchMe]'/>

</xsl:template> </xsl:stylesheet> Essentially you need to apply the template of any element, but only those whose name matches your request. Note that <xsl:apply-templates select='$matchMe]'/> doesn't work... :( So now if your PHP does something like $xslDom = new DOMDocument(); $xslDom->load('matchMe.xsl'); $xslt = new XSLTProcessor(); $xslt->importStylesheet($xslDom); $xslt->setParameter('','matchMe','umbongo'); $xmlDom = new DOMDocument(); $xmlDom->load('some_document_that_has_an_umbongo_tag.xml'); echo $xslt->transformToXML($xmlDom); you should get the results of the 'umbongo' template (only) 'f course, this is not tested, but I have used this idea in working code --

Utter brilliance, this is superb, I might drop you a mail to clarify a few things later Peter, but your reply was superb and has given me many options to try out. Thanks again!
