Hi Markus, > 1. But I can not exclude those subitems with attributes. > > <subitem typ="foo">not here</subitem> > > See bottom of testNumber.xsl : The problem here is that you're doing: preceding-sibling::subitem[@typ != 'foo'] which selects only those preceding sibling subitem elements that have a typ attribute whose value is not equal to 'foo', and thus excludes all the subitem elements that don't have a typ attribute. I suspect that you want to do: preceding-sibling::subitem[not(@typ = 'foo')] which selects only those preceding sibling subitem elements that do not have a typ attribute whose value is equal to 'foo', and thus includes all the subitem elements that don't have a typ attribute. > 2.

If you can use position() you should use position() instead to give the numbering, but that requires you to apply templates to the elements that you want to number, and only those elements, which might not be practical. > I guess xslt 2.0 would save me from all that hazzle... Unfortunately > I am restricted to xalan. Actually I don't think that XSLT 2.0 will be adding anything new in this department. What changes to XSLT or XPath do you think would help you achieve what you're trying to do more easily?
