Subject: [xsl] xslt node-set variable transversal From: "Kyle Partridge" <kpartridge@xxxxxxxxxxxx> Date: Tue, 30 Mar 2004 14:27:28 -0500 |
Hi, This is probably an obvious question, but I still haven't been able to get this to work. I've got an xpath that narrows a set of all the regions in the document, to the set of regions in a single "column": <xsl:variable name="col-regions" select="//ws:region[parent::ws:regions and @left>0 and (@left+@width)<$useable-page-width]"/> Then, I'm trying to iterate over that set: <xsl:for-each select="$col-regions"> <xsl:variable name="current-position" select="position()"/> <xsl:apply-templates select="." mode="horizontal-region-block"> <xsl:with-param name="following-regions" select="$col-regions[position()>=$current-position]"/> <xsl:with-param name="prev-region" select="$col-regions[position()=$current-position-1]"/> <xsl:with-param name="top-adjust" select="$top-adjust"/> </xsl:apply-templates> </xsl:for-each> but this doesn't work - the XMLSpy debugger says I am not getting anything in these params. I have tried this with using $col-regions[etc....] (like above) to try to get the following and preceding region or regions, and I have also tried it using preceding-sibling with an enormous xpath expression which, yet again, filters out regions that would not be in the current column. Using preceding-sibling with an enormous xpath expression seems to work - but I would rather not do an additional filtering every time I need to find the prev or next region in the $col-regions list. How come I can't just reach back or forward one? I am sure this is obvious but I just don't get it...I keep going back to the books, but I still don't understand. Thanks, KP
