Re: Removing if no data - iterating through every chil

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>

Mukul
