Hi Sebastian,
At 03:37 PM 3/2/2005, you wrote: I've got a template that needs to know the if it contains only 1 of a specific group of tags when it's within a "content" tag, and I've got this condition to do this: I have my doubts about its being more efficient (from several points of view it is likely to be less so), but a more explicit XSLT approach might at least *read* a bit more accessibly (whatever a processor does with it) -- <xsl:variable name="tags-count"> <xsl:for-each select="ancestor::content[1]"> <xsl:value-of select="count(tag1|tag2|tag3|etc)"/> </xsl:for-each> </xsl:variable> Then number($tags-count) is your count (remember $tags-count itself is a result tree fragment, which here contains a single text node with the value). Another way of simplifying this is to preprocess your input, for example by adding an attribute flag to all the element types you want to count. Then you collect them using that flag, instead of by name. The schema-awareness feature of XSLT 2.0 that Mike mentioned in connection with this might be considered to be an extremely sophisticated version of the last approach -- the schema annotates the document with type information, which you can then use in your transform. Cheers, Wendell
