 What I need is to get a distinct list of Pole val's and then for each Pole a distinct list of Time val's. (I need to be able to recreate this http://www.intermatic.com/comind/fdff.htm). When you say "distinct list of Time val's", your test data doesn't reflect duplicate values for time the way the web page does. I modified the data to include a duplicate for 6-hour single-pole single-throw switches. I find that using variables for multiple levels of uniqueness is better than using the Muenchian Method, but tastes vary. When using variables, the idea is to create a variable with all items from which uniqueness is determined, and then create a variable of those for each of those that are unique and find uniqueness within those variables. This avoids concatenating key values for each level of uniqueness in the Muenchian Method. The first of each variable for each value is determined using generate-id() since generate-id() only works on the first member of a passed node set. An example is below ... I hope this helps. ................. Ken
<xsl:output method="text"/> <xsl:template match="/">
<xsl:variable name="products" select="/products/product"/>
<xsl:for-each select="$products">
<xsl:if test="generate-id(.) =
generate-id( $products[ product_fact[@name='Pole']/val=
current()/product_fact[@name='Pole']/val ])">
<xsl:value-of select="product_fact[@name='Pole']/val"/>
<xsl:text>
</xsl:text>
<xsl:variable name="times"
select="$products[ product_fact[@name='Pole']/val=
