My input documents are allowed to contain nested sections. An optional attribute marks out certain sections as significant. I want to detect a situation in which a section which contains a descendant significant section does not contain a subsequent INsignificant section (other than descendants of any significant sections). It's complicated because the nested sections are not (necessarily) immediate descendants of each other. I'm afraid I cannot readily understand what you want, but I can focus on your choice of wording to make an attempt at an answer. if the section it is wrapped in did not have the significant attribute set then So you want descendants of sections without the attribute that have a preceding sibling with the attribute. I'm a bit stuck with this template, which identifies the correct ancestor, Why the ancestor? Above you want to report the wrapped section, not the wrapping section. It surely isn't as complex as I'm finding it, can anybody help please? It might be because of the complexity of describing it. <xsl:template match="section[@sig="Y"]> I don't think you want to focus on a section *with* significance, as I interpret you want to report the descendants with the problem.
