Joe says: "Apples, Bananas,Oranges." Even if this is not what you really want, it's interesting to see how it works out. I have not completely handled putting in commas everywhere except a period for the last item - I leave this to the reader. I also haven't translated the first character of the name to upper case - Jenni covered that. I also sorted the result by name. The solution is very compact without those refinements: ========================================================== <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method='text'/> <!-- key for using the Muenchian method of getting unique node sets--> <xsl:key name='wrappers' match='wrap' use='name(*)'/> <!-- Elements with unique person names --> <xsl:variable name='unique' select='/root/wrap[generate-id(key("wrappers",name(*)))=generate-id(.)]'/ > <xsl:template match="/"> <xsl:for-each select='$unique'> <xsl:sort select='name(*)'/> <xsl:variable name='theName' select='name(*)'/> <xsl:value-of select='$theName' /> says: <xsl:for-each select='key("wrappers",$theName)' ><xsl:value-of select='normalize-space(.)' />, </xsl:for-each><xsl:text> </xsl:text> </xsl:for-each> </xsl:template> </xsl:stylesheet> ======================================================== The slightly odd formatting is an easy way to control the output format while still having short line lengths in the stylesheet (better for emailing), and the character reference is necessary on my (Windows) system to get the line feed to display. Here is the result (I added another person, bob, to the data, just for fun): =========================== ann says: Pears, bob says: Peaches, joe says: Apples, Bananas, Oranges, =========================== This was interesting because the usual examples for getting unique node-sets assume you know what the target elements are named, but not in this case.
