is straight forward in code, but not sure how to do it xsl?  Basically the
output would be topic1,2 and 3 from category1 and topic 1 from category 2

i've done an example in  a procedural style to be clear for you, this is
just one way of doing this

xml
----------------------------------
<?xml version="1.0" ?>
<root>

<category value="category1">
  <topic value="topic1"/>
  <topic value="topic2"/>
  <topic value="topic3"/>
</category>
<category value="category2">
  <topic value="cattopic1"/>
  <topic value="cattopic2"/>
  <topic value="cattopic3"/>
</category>

</root>

xsl
---------------------------------
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
 <xsl:template match="/">


 <xsl:for-each select="//topic">

 <xsl:if test="position() &lt; 4">
 <xsl:value-of select="@value"/>
 </xsl:if>

 </xsl:for-each>
 </xsl:template>
</xsl:stylesheet>
