does anyone know how to set the context node when processing an xml document with xsl? i.e. how do you move the context node to another node further up/down the document?

i thought i could do it by using <apply-templates select="another node"/>, but i still get stuff outputted from nodes between the node where the apply-templates is called and the one selected!?

thanks!!

Try using xsl:match-template.

i've written a load of code below. if you run it, then you'll see that none of the blocks of document nodes are missed which is what i'm trying to do.

Code: 
<?xml version="1.0" encoding="UTF-8"?>

<!-- source document to be transformed -->

<doc>
 <page>
  <content>
   <para>
    <run>
     <text>
      <condition eval="THIS = 'TEST'">&lt;&lt;IF THIS = 'TEST'&gt;&gt;</condition>
     </text>
    </run>
   </para>
   <para>
    <run>
     <text>IF EVALUATED TO TRUE!!!</text>
    </run>
   </para>
   <para>
    <run>
     <text>
      <condition eval="ELSE">&lt;&lt;ELSE&gt;&gt;&lt;&lt;IF THIS = 'TEST'&gt;&gt;</condition>
     </text>
    </run>
   </para>
   <para>
    <run>
     <text>IF EVALUATED TO FALSE!!!</text>
    </run>
   </para>
   <para>
    <run>
     <text>
      <condition eval="END">&lt;&lt;ENDIF&gt;&gt;&lt;&lt;IF THIS = 'TEST'&gt;&gt;</condition>
     </text>
    </run>
   </para>
  </content>
 </page>
</doc>

Code: 
<?xml version="1.0" encoding="UTF-8"?>

<!-- source document's condition information (merge-data.xml) -->

<dataset>
 <condition ref="&lt;&lt;IF WEATHER = 'BAD'&gt;&gt;">TRUE</condition>
 <condition ref="&lt;&lt;IF THIS = 'TEST'&gt;&gt;">TRUE</condition>
 <condition ref="&lt;&lt;IF THISDATA = 'RANDOM'&gt;&gt;">TRUE</condition>
</dataset>

Code: 
<?xml version="1.0" encoding="UTF-8"?>

<!-- xslt stylesheet -->

<xsl:stylesheet version="1.0"
