[xsl] problem retrieving node attribute value

[RQamar <qamar_rahil@xxxxxxxxxxx>]

Hi

I'm reposting as I've made a few changes to my code.

The <xsl:template> block below is the code I've written to find a concept 'Pain' and then its child/grandchild 'Headache' from an xml file.

However the result aint accurate (I've explained the problems after the code).


-------------------------------------
<xsl:template match="DEFCONCEPT" mode="top">
	 <xsl:if test="@name = $prime"> <!--e.g. resolves to 'Pain'>
	 	<xsl:attribute name="id"><xsl:value-of select="@id"/></xsl:attribute>
		<xsl:element name="PrimeName"><xsl:value-of select="@name"/></xsl:element><!-- e.g. Pain-->
		<xsl:if test="following-sibling::DEFCONCEPT[@name = $constraint] | preceding-sibling::DEFCONCEPT[@name=$constraint]"> 
										<!--e.g. resolves to 'Headache'>			
			<xsl:element name="SubConcepts">
				<xsl:element name="SubConcept">
					<xsl:attribute name="id"><xsl:value-of select="@id"/></xsl:attribute>
					<xsl:attribute name="name"><xsl:value-of select="@name"/></xsl:attribute>
				</xsl:element>
			</xsl:element>
		</xsl:if>
	</xsl:if>	
</xsl:template>

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

The resulting output is such

------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<Top>
<PrimeConcept id="10180">
  <PrimeName>Pain</PrimeName>
  <SubConcepts>
      <SubConcept id="10180" name="Pain"/> <!-- it should really be 'Headache'-->
  </SubConcepts>
</PrimeConcept>
</Top>
------------------------------
I have two problems though. First, my <SubConcept> element tag displays 
'Pain' and '10180' instead of 'Headache' and '10279'. Is that because 
the control still remains at the 'Pain' element? How do I resolve this issue?

Second, the actual output I'd like is
<PrimeConcept></PrimeConcept>
<SubConcepts>
  <SubConcept></SubConcept>
</SubConcepts>

but I'm not sure how to create a top-level node <SubConcepts> from 
within the <PrimeConcept> if clause.

Could someone please help  me out with this?

Thank you
Rahil
