Re: [xsl] Checking value of a previous text node

["Vasu Chakkera" <vasucv at hotmail dot com>]

with what you have described, it looks to me that you would want to group 
the names with quarter-names.. The following grouping method would help you.

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:key name="name" match="/root/enrolledClasses/class" use="quarterName"/>
<xsl:template match="/">
<xsl:for-each select="/root/enrolledClasses/class[not(quarterName = 
preceding-sibling::class/quarterName)]">
<i><xsl:value-of select="quarterName"/></i><br/>
<xsl:for-each select = "key('name',quarterName)">
<xsl:value-of select="name"/><br/>
</xsl:for-each>
<hr/>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
