In general I think the answer should be that you cannot have a single XPath expression for the above without also including in it some variable references. In any specific case the answer may be different. For example, if it is the case that a "channelDetailId" attribute value uniquely identifies an "interval" element, then the following XPath expression will yield the desired result: endTime[interval/@channelDetailId != following-sibling::endTime[1]/interval/@channelDetailId ] This will be even simpler if we knew that an "endTime" has only one "interval" Cheers, Dimitre Novatchev. __________________________________________________ Do You Yahoo!?
