Dear Peter, When you write /html/body/xforms:group that actually means the html element from no namespace the body element from no namespace the grop element from http://www.w3.org/2002/xforms/cr" namespace When you specify an unqualified element in XPath that means it belongs to no namespace. More there is no way to specify an element from the default namespace (with default namespace != no namespace) in XPath. In order to refer to such elements you can map the default namespace to a prefix using xmlns:prefix="defaultNamespace" and then use prefix:element or use instead of element a construct like *[local-name()='element'] Oxygen uses Xalan for XPath evaluation. It has an implementation specific behavior that allows you to access an element from the default namespace if you specify it as :element so /:html/:body/xforms:group will give you the expected result. However this is not recommended and you should use one of the alternatives I specified above: /*[local-name()='html']/*[local-name()='body']/xforms:group or /html:html/html:body/xforms:group together with adding a mapping from html to "http://www.w3.org/1999/xhtml" Best Regards, George ------------------------------------------------------- George Cristian Bina mailto:george@oxygenxml.com <oXygen/> XML Editor - http://www.oxygenxml.com/ ----- Original Message ----- From: "Peter Charles" <petefc@sims.berkeley.edu> To: <oxygen-user@oxygenxml.com> Sent: Friday, February 06, 2004 9:07 PM Subject: [oXygen-user] Xpath Evaluator Bug?

Hello,

Using this file, I was able to match the expression //xforms:group, however, I was not able to match the expression /html/body/xforms:group. When I copied the found xpath expression from the //xforms:group query (/html[1]/body[1]/xforms:group[1]/xforms:label[1]) , the expression would not evaluate.

Using version 3.0
