Hello Tom,
you created a little bit oversized Muenchian Method. I wonder if you could use a key? How about <xsl:key name="firsts" match="//Content[not(./preceding::Content/@ContentText=./@ContentText)]" use="@ContentText"/> With your key you only have these nodes in your key-table, which are the first with its attribute value. So you would not need the Muenchian Method itself: <xsl:when test="(count(. | key('firsts',@ContentText)) = 1)"> An easy key('firsts',@contentText) would be enough. But your code removes the real advantage of using keys. What you have in your key, you can write easily in your <xsl:when>. You don't need the key. <xsl:when test="self::Content[not(preceding::Content/@ContentText = @ContentText)]"> It's more a processing time problem then an error. Jeni gave already the correct code. And one more comment: in the matcher of <xsl:key> you don't need '//'. The key is created for all Content elements in the file, independent on its level.
