Then you might need something

<PrimeConcept><xsl:apply-templates

<SubConcept><xsl:apply-templates select="something else

</Top>
</xsl:template>
or you might not.
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

but only you know what your input looks like or what transformation you
are trying to do.
