I think from what you've described you want to take the SHIPMENT_GID from the current REPORT_CUSTOMER and use that to access the COST element that has that particular value for its sibling SHIPMENT_GID. Whenever you want to repeatedly access a set of elements by their value on a particular child (or attribute), you should use a key to make the search more efficient. So you should set up a key that indexes the COST elements by their SHIPMENT_GID like so: <xsl:key name="costs-by-gid" match="COST" use="parent::ROW/parent::REPORT_COST/ROW/SHIPMENT_GID" /> Now if you have a GID of '123' you could get the COST for that shipment with: key('costs-by-gid', '123') If the GID is held in the SHIPMENT_GID child element of the current ROW then you can display the value with: <xsl:value-of select="key('costs-by-gid', SHIPMENT_GID)" /> or if you're iterating over elements that have the SHIPMENT_GID elements as their children then you can sort on that value with: <xsl:value-of select="key('costs-by-gid', SHIPMENT_GID)" /> Note that you need something a little bit more complicated given the XML that you describe because the ROW elements that you're iterating over are not the ROW elements that contain the SHIPMENT_GID for a particular REPORT_CUSTOMER. I hope that helps, Jeni --- Jeni Tennison http://www.jenitennison.com/ XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
