I wrote my code in this form initially although I didnt think it was 
ideal for my requirement.

By writing a <SubConcept> node in this form, the output xml file ensures 
that a <SubConcept> node definitely exists. However, I want the output 
xml file to have a <SubConcept> node only if

(i) A <TopNode> Car is found in the input xml, and
(ii) A <TopNode> Toyota is found in the input xml provided (i) is true, 
which is why I have an <xsl:if> clause nested within another <xsl:if> 
clause.

My input file is very large so Im not sure whether it makes sense to 
post the entire doc but a snippet of it is

-------------------
<TopNode id="10180" name="Car">
     <Child>
          <Concept name="Toyota" ref="10235"/>
      </Child>
</TopNode>
<TopNode id="10235" name="Toyota">
      <Child>
          <Concept name="Corolla" ref="10279"/>
      </Child>
</TopNode >
<TopNode id="10279" name="Corolla"/>

-------------------

Is it possible to do what I want? One way I was thinking of coming round 
this problem is to declare a global variable and then assign it a value 
locally (I know there are some issues with assignment in XSLT and Im 
reading them at the  moment). This variable will contain a boolean value 
of whether 'Toyota' exists from the inner <xsl:if> clause and only call 
the <SubConcepts> <xsl:apply-template> if the value is 'true'. Dont know 
if its the best approach but that was one way I was thinking of 
resolving the issue.

Comments?

Thanks
