You don't set XPointers - you use XPointers to refer to a fragment of a document in the URI you pass to the document() function.

As far as I know, there are none that support the XPointer scheme (which is not a W3C recommendation - only the element and xmlns schemes made the recommendation). Gestalt has a gexslt:xpath2 scheme, so you could use that to select the nodes you want. I think the XPath expression you want is (assuming the first div you show is the first child element of the document element): /*/div[1]/*[position gt 2 and position lt 7] Tom> PS: using XSLT 2.0 - guess the processor doesn't matter for Tom> that question!? It does matter. Which XPointer schemes (if any) are supported by an XSLT processor is implementation-defined. -- Colin Adams Preston Lancashire
