Hi Martin, Personally, I see "recursion solutions" as a kind of a workaround for one of XSLT's shortcomings -- namely no traditional variables -- and they make it difficult to understand what's going on in the script (if not for the original developer, then for any subsequent support staff trying to take over maintenance). AND, if you ARE talking about a really huge table, and it causes your transformation "to exlode" (nice imagery Geoff :-), then you can't use it at all. I'd suggest two alternatives: 1) If you are using a parser that supports javascript scripting as callable functions from the XSL (Microsoft's is one), you could create a "global" javascript variable that truly does get incremented during each table row output, and whose value can be queried to determine odd/even; or 2) Split your XSLT process into two distinct passes: one which sorts/filters/etc. the data into the desired order, and another which operates on the result of the first and simply looks at the (position() mod 2) to determine odd/even. Each of these options have their downsides, and may prove undoable for your situation, but I think they are more straightforward in their logic than the recursive approach. Hope this helps!

That would allow you to have a variable that increments for each element that passes the filter, and you could use the modulus test on that. -----Original Message----- Martin Snajdr|AMAN Sent: Tuesday, May 23, 2006 1:16 AM To: xep-support@renderx.com Subject: [xep-support] "Filtered" Select and alternating background-color Hi there, i have a problem with a real huge table, which has to have alternating background-color in each table-row. As you can see in the following excerpt, i have to use a xsl:if to filter the select. But doing it this way prevents the position()-thing from working right, when the filter is active. [..] <fo:table-body> <xsl:for-each select="article"> <xsl:if test="(($filter_material='all') or($filter_material!='all'and @color=$filter_material)) and (($filter_knaggen='all') or($filter_knaggen!='all' andcontains(./attributevalue[@attid=$filter_knaggen_attrid]/value[@lang= ' de'],$filter_knaggen) )) and (($filter_nenngroesse='all') or($filter_nenngroesse!='all'andcontains(./attributevalue[@attid=$filter_nenngroesse_attrid]/value[@lang='de'],$filter_nenngroesse) )) and (($filter_eingang='all') or($filter_eingang!='all' andcontains(./attributevalue[@attid=$filter_eingang_attrid]/value[@lang='de'],$filter_eingang) )) "> <fo:table-row page-break-inside="avoid"> <xsl:attribute name="background-color"><xsl:if test="position()mod2=0">rgb-icc(255,255,255,#CMYK,0,0,0,0)</xsl:if><xsl:if test="position() mod 2 != 0">rgb-icc(227, 231, 241,#CMYK,0.1,0.045,0,0.05)</xsl:if></xsl:attribute> [..] I tried to change the select to do the filtering, but since the filter depends on passed-in params i'm not able to do this. I tried some exslt node-set-stuff, but i didn't get to it.
