Re: [xsl] Merging nested/adjacent nodes

[David Carlisle <davidc@xxxxxxxxx>]

Turns out that this is simpler than it looks, simpler than I thought it
was going to be anyway. Powerful voodoo this for-each-group stuff....


emp.xsl:

<xsl:stylesheet
   version="2.0"
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
>

<xsl:output indent="yes"/>
<xsl:strip-space elements="*"/>


<xsl:template name="m" match="*|/">
<xsl:param name="c" select="*"/>
<xsl:for-each-group select="$c" group-adjacent="string(@name)">
<xsl:copy>
<xsl:copy-of select="@*"/>
<xsl:call-template name="m">
 <xsl:with-param name="c" select="current-group()/*"/>
</xsl:call-template>
</xsl:copy>
</xsl:for-each-group>
</xsl:template>

</xsl:stylesheet>


emp.xml

<employees>
        <supervisor name="jimmy">

        <supervisor name="jimmy">
