Subject: RE: [xsl] unique attribute values in XSLT2 - storing them in a variable From: "Michael Kay" <mike@xxxxxxxxxxxx> Date: Tue, 22 Feb 2005 11:09:37 -0000 |
You just need <xsl:variable name="x" select="distinct-values(/A/B/C/@atc)"/> Your construct <xsl:for-each-group select="B/C" group-by="."> is unnecessary and achieves nothing: the C elements are all empty, so they all have the same grouping key, so they all go in a single group.
