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,

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:


<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]'/>


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();
$xslt = new XSLTProcessor();
$xmlDom = new DOMDocument();
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!
