The following XUpdate query, which uses XPath works under Xindice no probs:
<xupdate:modifications version="1.0" xmlns:xupdate="http://www.xmldb.org/xupdate";> <xupdate:update select="/Classes/Class[last()]/@id">999</xupdate:update> </xupdate:modifications> please note the XPath: /Classes/Class[last()]/@id Why does it work for XUpdateQueryService, but not for XPathQueryService? I may have a play around with the source code to see what's happening. Thanks Dominic Gamble On Fri, 2002-04-05 at 17:49, Mark J.
