Re: XPath - How to select preceding nodes that are de
I have an XML document with multiple subtrees starting at element 'SUBTREE' containing 'LEAF' leaf element descendants at various hierarchical depths. I need to know - for each 'LEAF' element - how many preceding 'LEAF' elements there are within the closest ancestor 'SUBTREE'.
I would treat it like figure numbering in a book, where the figures can be anywhere in preceding subtrees, and let the processor do the counting for you:
<xsl:variable name="count-temp"> <xsl:number count="LEAF" from="SUBTREE" level="any"/> </xsl:variable> <xsl:variable name="count" select="number($count-temp) - 1"/>
This won't be negative because you said you would be counting from a LEAF.
I hope this helps.
