By default, IIRC, the namespace mappings used in the XPath expression are the same as those in the Document you run the query against. But using plain XPath you could do something like this):
/aaa[namespace-uri(.) = 'http://www.dom4j.org']/bbb[namespace-uri(.) = 'http://www.dom4j.org']
alternatively (using the dom4j api) you could also do something like this:
XPath xp = DocumentFactory.getInstance().createXPath("/foo:aaa/foo:bbb");
Map nsMap = new HashMap();
nsMap.put("foo", "http://www.dom4j.org");
xp.setNamespaceURIs(nsMap);
xp.selectNodes(yourContextNode);
Hope this helps,
