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() < 4">
<xsl:value-of select="@value"/>
</xsl:if>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
