Well, I think that's a *bit* harsh. But the "YMMV" addition was appreciated, because it can and will. That is, if the XML is completely consistent, then Kyle's suggestion is an excellent one. If it isn't, then Kevin's link applies, IMHO. Since it appears from what we have been told that the records are consistent, I think Kyle's solution is not only workable but the most efficient. Given the caveat stated above.
