FFFAQ,
I need help to write an XSLT file for converting first.xml to
second.xml
where the attribute values are grouped
Did you have a look at the FAQ or Jeni's pages on grouping?
<xsl:key name="class" match="student" use="@class"/>
<xsl:template match="school">
<xsl:copy>
<xsl:for-each select="student[generate-id(.) = generate-id(key('class',
@class))]">
<Section class="A">
<xsl:apply-templates select="key('class', @class)"/>
</Section>
</xsl:for-each>
</xsl:copy>
</xsl:template>
<xsl:template match="student/@class"/>
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
Cheers,
Jarno
