This is again the dreaded default namespace problem. The XPath expression //resource searches for all elements that are not in a namespace and are named 'resource'.
In this case the //resource elements are in the 'http://www.imsglobal.org/xsd/imscp_v1p1' namespace. XPath however does not allow us to specify that it should look for the elements in the default namespace. To solve this you should be allowed to specify a mapping between your namespace and any arbitrary prefix, and use this prefix to search for elements in that namespace. So let's say you specified 'ims' as the prefix for your namespace, you could now look for your resource elements using the following XPath expression: //ims:resource Most XPath processors allow you to specify a namespace prefix mapping and dom4j allows this as well using the 'setXPathNamespaceURIs' method on the DocumentFactory. The code should look something like this: HashMap map = new HashMap(); map.put( "ims", "http://www.imsglobal.org/xsd/imscp_v1p1";); DocumentFactory.getInstance().setXPathNamespaceURIs( map); executeXPath( document, "//ims:resource"); Note: This mechanism can also be used to search documents where the namespace prefix changes between documents. (some people prefer 'xs' as the prefix for the xml-schema namespace, others prefer 'xsd') Regards, Edwin ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
