Yah, though setting to a variable is outside the scope of the XPath REC, no? We (at jaxen.org) have had many discussions, particular regarding //foo and our breadth-first walk of the tree instead of depth-first. We sometimes end up with nodes out-of-document-order. Technically, I think we're compliant, but it sure can annoy the user. ;) -bob
