Re: [xsl] processin each element not on a list

[Joerg Heinicke <joerg dot heinicke at gmx dot de>]

Hello Dan,

a really efficient solution is the usage of keys:

<xsl:key name="choices" match="choice" use="."/>

<xsl:template match="root">
  <xsl:apply-templates select="items"/>
</xsl:template>

<xsl:template match="items">
  <xsl:apply-templates select="item[not(key('choices', .))]"/>
</xsl:template>

<xsl:template match="item">
  ...
</xsl:template>

Regards,

Joerg
