Omprakash,

In your case, the  relation of university and college is parent-child .. it
is not following..
a Following axes is defined as..nodes that come after the context node in
the document order.This means that the opening tag of the node must come
after the closing tag of the context node and therefore excludes the
descendants of the context node

so you could do
<xsl:choose>

<xsl:template match="university">

<xsl:choose>
    <xsl:when test ="*[1][self::college]">
 <!-- this means when university ( the context node ) has a first child
called college , then print college name here
        This is equivalent to saying <xsl:when test = "child::college">
-->
    print college name here
    </xsl:when>
</xsl:template>

<xsl:otherwise>
   do nothing
</xsl:otherwise>
</xsl:choose>



Hope this helps
Vasu
