Subject: [xsl] Counting preceding nodes From: "Billie" <whynot77@xxxxxxxxxxxxx> Date: Fri, 24 Jun 2005 13:29:05 -0400 |
I need help with a problem I'm having. I need to count the number of nodes that come before the given node, anywhere in the tree. So for example, say I have this tree: <book> <chapter> <para> Blah blah blah <diagram name="first"/> </para> <para>Blah blah blah</para> <para> <diagram name="second"/> Blah blah blah </para> <diagram name="third"/> </chapter> <chapter> <para>Blah blah blah</para> </chapter> <chapter> <diagram name="fourth"/> <para>Blah blah blah</para> </chapter> <chapter> <para> <quote> <diagram name="fifth"/> <diagram name="sixth"/> Blah blah blah </quote> </para> </chapter> </book> I gave the diagrams the appropriate names so you could see what I was looking for, but basically, I'm looking for a way to number the diagrams based on the absolute order in which they are placed. I've tried all sorts of combinations but nothing seemed to work. One logical structure I came up with, that I couldn't figure out how to translate into XSL, was: "count the number of diagrams that have an ancestor-or-self which is a preceding-sibling to an ancestor-or-self of the diagram in question". Is that possible to do? <xsl:template match="diagram"> <xsl:attribute name="Number"> <xsl:value-of select="???"/> </xsl:attribute> </xsl:template> Thanks for your help, Billie
