The spec says that a non-prefixed name means a name in the ***null*** namespace, not the default namespace. "A QName in the node test is expanded into an expanded-name using the namespace declarations from the expression context. This is the same way expansion is done for element type names in start and end-tags except that the default namespace declared with xmlns is not used: if the QName does not have a prefix, then the namespace URI is null" (http://www.w3.org/TR/xpath#node-tests) Therefore, if the default namespace is not null (,which is the case) the result of evaluating the XPath expression "//hr " will not contain "hr" elements from the default namespace. On the other side, "//html:hr " will return all of them. ===== Cheers, Dimitre Novatchev. http://fxsl.sourceforge.net/ -- the home of FXSL __________________________________________________ Do You Yahoo!?
