AW: XSL equivalent to SQL "unique"

Hmm, 

looks like I've got a syntax or rtf/node-set problem, all methods
descibed there would apply easily if I had entries like

<set name="1">
	<entry name="a">v1</entry>
	<entry namw="b">v2</entry>
</set>

but all my trials to convert from the below format to that
seem to end at the result-tree-fragment/noed-set boundary. E.g.
I'd like to write

<xsl:variable name="all">
	<xsl:for-each select="set/*">
		<name><xsl:value-of select="name()"/></name>
	</xsl:for-each>
</xsl:variable>

to convert below data into above format in the variable $all.
But the result is a result tree fragment which cannot be processed
by another for-each loop. I cannot figure a workaround for the
obstacle. 

Of course one could it with two xslt steps, but this would be
very inconvenient in the framework I currently use...

Still puzzled,
Frank
