Re:  Keeping track of processed nodes
Hi John,

You can define a key that matches enElement and use the name attribute. Then you can process only the first element that matches a given value:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:key name="name" match="anElement" use="@name"/>
<xsl:template match="/">
<xsl:template match="anElement">
<xsl:if test="generate-id(.)=generate-id(key('name', @name)[1])">
<name><xsl:value-of select="@name"/></name>

This is a simplified description of what I am trying to do, I have an
xml document like this:

    <anElement name="John" />
    <anElement name="Jane" />
    <anElement name="John" />
    <anElement name="Jane" />

and I like to retrieve each 'name' attribute from 'anElement', but I only want to process the name once. So if the 'John' attribute is repeated I want to somehow keep track that I have already processed it, hence there is no need to process it again.

So for the given example I like to output something like:


Thanks, John
