Hi Dare Have a look at the XQuery and XPath Data Model document. Both XPath2 and XQuery share the same data model as defined in the document at http://www.w3.org/TR/query-datamodel/.
You are right that primitive types are the schema primitive types - all the usual suspects - float, decimal, double, datetime and about 20 others. As well, the data model supports sequences of primitive types, sequences of nodes (like nodesets)as well as a single node. A node can be a document, element, attribute, comment... At any rate, it is quite well spelled out in the aformentioned document. cheers Jim > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > Behalf Of Dare Obasanjo > Sent: Saturday, January 12, 2002 7:48 PM > To: [EMAIL PROTECTED] > Subject: Re: Problems With Implementing XMLDB API > > > The valid return types from an XQuery query are XML schema types while the > valid return types from an XPath 1.0 query are a boolean, string, > number, or > nodeset (is there one I've forgotten?).
