Thanks a million! This solution works, however, initially I get a one-celled table, so I changed the initial selectNodes XPath to be: /Index/document[starts-with(user,'')] This matches everything, of course, so I get the table with rows and cells again. Thanks again!

I haven't tested this code, but it should work. Also note that I change for your 'for' loop to a more efficient 'while' loop. For large datasets, using the nextNode() method can be _much_ more efficient. //add XML content to table var oNode; while ( null != (oNode = oDisplay.nextNode())) { var oRow = tblXML.insertRow(); var oChildren = oNode.childNodes; var oChild; while ( null != (oChild = oChildren.nextNode())) { var oCell = oRow.insertCell(); oCell.innerHTML = oChild.xml; } } Derek Denny-Brown -- Technical Lead: MSXML -- <http://msdn.microsoft.com/xml> > -----Original Message----- > From: White, Solomon [mailto:Solomon_White@a...] > Sent: Friday, May 18, 2001 12:56 PM > To: Xml-Dev Mailing List (E-mail) > Subject: MSXML XPath question > > > Hello all-- > > I have a question regarding the use of XPath in IE5+.
