[xsl] dynamic node access

[RQamar <qamar_rahil@xxxxxxxxxxx>]

Hi

I am trying to retrieve an attribute value from a particular node, which 
has been reached dynamically. However the control tends to remain on the 
previous node. So my code

<xsl:if test="following-sibling::TopNode[@name = $constraint]"> <!--e.g. 
should display 
'Toyota'>                                                              
                         
          <xsl:attribute name="id"><xsl:value-of 
select="@id"/></xsl:attribute>
          <xsl:attribute name="name"><xsl:value-of 
select="@name"/></xsl:attribute>
</xsl:if>

still returns 'Car' instead of 'Toyota'. This <xsl:if> is inside another 
<xsl:if> clause which returns 'Car'. How can I get the control to move 
to the node which contains the @name=Toyota ?

Could someone please help as I cant find any relevant information.

Thanks
Rahil
