Hi Jeff and Michael - Thanks for your suggestions, however, they also do not seem to work for me accessing documents in the Xindice database. (Do they work for you using the Xindice command tools?)
It seems to me that this is Xindice-specific and has to do with how XPath and XIndice interact because the "isModified=" and the isModified/text(), etc. methods actually return the Xindice document i.e.: <isModified xmlns:src="http://xml.apache.org/xindice/Query"; > src:col="/db/catie_3 > 3eecca6-6921-44d2-a191-861a77bc5d82/session_xml" > src:key="841c44e9-54b9-4204-b0d > 2-f7bf0ed81426">false</isModified> instead of the value "false". Do you have other suggestions or is there something I missed in your emails? Thanks again for the help!

That post has to do with trying to retrieve *only* an attribute value -- Xindice/xmldb requires that the containing element of that attribute be returned. I think your XPath query that isn't quite right. This works for me (using Xalan outside Xindice) on your document: '/session/header[isModified="false"]' The way I read this query is "retrieve the header children of the session root element which have isModified elements whose string value is 'false'." The part before the left square bracket is what is to be retrieved, and you can think of the left square bracket as meaning 'such that' and carrying the node context of the expression preceding. Thus expr1 [expr2] means retrieve all nodes matching expr1 such that expr2 is true, with expr2 evaluated in the context of each node selected by expr1.
