Re: designing a xsl:uniq function
Perhaps a new command for XSLT 2.0 ? It would look like : <xsl:for-each select="//indexentry[@level1=$my_first_level and @level2]"> <xsl:sort select="@level2"/> <xsl:uniq select="@level2"/> [...] </xsl:for-each> What do you think of it ? this is really just the "grouping" problem (the simple case where you only process the group as a whole and not the individual elements) see the XSLT2 requirements document (http://www.w3.org/TR/xslt20req) for some thoughts on grouping. xsl:uniq is slightly problematic as you have to decide which of the elements you keep. They may all have th esame sort key but they are different nodes so "." generate-id(.) etc would have different values depending on which node was chosen. for this reason it's probably better to have a grouping construct that lets you access each group of nodes with the same sort key, and lets you chose in the stylesheet which if any node out of each group that you process.
