Subject: RE: [xsl] How to select nodes with explicitly set default namespace - DOM4J From: "Michael Kay" <mike@xxxxxxxxxxxx> Date: Wed, 23 Mar 2005 15:54:31 -0000 |
In XPath 1.0, if you want to select an element that's in a namespace, you need to bind a prefix to that namespace and use a prefixed QName in the path expression. The fact that the namespace is the default namespace in the source document makes no difference.
