Re: [xsl] Filtering nodes

[Joerg Heinicke <joerg.heinicke@xxxxxx>]

<xsl:template match="Record">
  <xsl:copy>
    <xsl:copy-of select="@*"/>
    <xsl:apply-templates/>
  </xsl:copy>
</xsl:template>

<!-- empty records -->
<xsl:template match="Record[not(@*)]">
  <xsl:apply-templates/>
</xsl:template>

<!-- records with leaves -->
<xsl:template match="Record[Leaf]">
  <Leaf Name="{@Name}"/>
</xsl:template>
