I don't know anything about XPathAPI, but by just
looking at the two items you posted you are using the
wrong case. Meaning "/report/link" is not the same as
"/Report/Link" - just as Torsten is not the same as
torsten (perhaps you have been spoiled :)

google says:

selectNodeList

public static NodeList selectNodeList(
 Node contextNode, java.lang.String str,               
                      Node namespaceNode) throws
TransformerException

Use an XPath string to select a nodelist. XPath
namespace prefixes are resolved from the namespaceNode.

Parameters:
contextNode - The node to start searching from.str - A
valid XPath string.namespaceNode - The node from which
prefixes in the XPath will be resolved to
namespaces.Returns:
A NodeIterator, should never be null.Throws:
TransformerException -
