Hi Mukul,
Thanks for this. It appears to work really well in my test cases.
It think, it's also a very handy bit of code to have around.

Hi Bryan,
Please try this XSL -
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="xml" indent="yes"/>
<xsl:template match="node()">
<xsl:variable name="flag">
<xsl:for-each select="@*">
<xsl:if test="normalize-space(.) != ''">
1
</xsl:if>
</xsl:for-each>
<xsl:if test="normalize-space(.) != ''">
1
</xsl:if>
<xsl:for-each select="descendant::*">
<xsl:for-each select="@*">
<xsl:if test="normalize-space(.) != ''">
1
</xsl:if>
</xsl:for-each>
<xsl:if test="normalize-space(.) != ''">
1
</xsl:if>
</xsl:for-each>
</xsl:variable>
<xsl:if test="contains(normalize-space($flag),
'1')">
<xsl:copy>
<xsl:for-each select="@*">
<xsl:attribute name="{name()}">
<xsl:value-of select="." />
</xsl:attribute>
</xsl:for-each>
<xsl:apply-templates />
</xsl:copy>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
Regards,
Mukul
