Re:  processin each element not on a list
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

I have xml in substantially the following form:

<root>
 <choices>
  <choice>A</choice>
  <choice>B</choice>
  <choice>C</choice>
  <choice>D</choice>
 </choices>
 <items>
  <item id="1">A</item>
  <item id="2">X</item>
  <item id="3">B</item>
  <item id="4">C</item>
  <item id="5">Y</item>
  <item id="6">Z</item>
 </item>
</root>

I need to process each item where its content is not one of the
choice values. I need a very efficient solution since I have say
up to 10,000 <items>s and perhaps 100 difference <choice>'s.


Thanks in advance.
