Hi:
Try this:
final Element java =
doc.getOwnerDocument().createElement("DslContext");
java.setAttribute("xmlns:dsl",
"http://www.applyweb.com/dsl";);
// for eval function
XPathAPI.eval(node, xpath_expr, new
PrefixResolverDefault(java));
// for select*** function
XPathAPI.selectSingleNode(node, xpath_expr, java);
Bye.
