Re: Recursively removing empty tags from deepest child

I slightly modified the XSL. This seems to work.

<?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" version="1.0"
encoding="UTF-8" indent="yes"/>

<xsl:template match="/">
    <xsl:apply-templates mode="copy"/>
</xsl:template>

<xsl:template match="@*|node()" mode="copy">
    <xsl:copy>
      <xsl:apply-templates select="@*|node()"
mode="copy"/>
    </xsl:copy>
</xsl:template>

<xsl:template match="//section|//p" mode="copy">
    <xsl:if test="normalize-space(.)">
        <xsl:copy>
          <xsl:apply-templates select="@*|node()"
mode="copy"/>
        </xsl:copy>
    </xsl:if>
</xsl:template>    	
</xsl:stylesheet>
