XPath 1.0 is not "relationally complete", that is, there are queries expressible in first-order predicate calculus that are not expressible in XPath 1.0. This might well be one of them. In such cases you need some assistance from the host language (e.g. XSLT or Java).

Does that mean the question is to complex to be treated with xPath 1? ... I know, if we have an easy way to go why bother about the longer ones...
Cheers Leo
