Set the "SelectionNamespaces" property to a string that looks like the
namespace declarations that you're using and then use those prefixes
in the path:

  XMLDOM.setProperty("SelectionLanguage", "XPath");
  XMLDOM.setProperty("SelectionNamespaces",
                     "xmlns:alk='http://foo' xmlns:xyz='http://goo'")
  nodes = XMLDOM.selectSingleNode("/alk:root/xyz:bar");

Note that all the namespaces that you use have to be assigned a
prefix -- any element name in the path that doesn't have a prefix will
be assumed to be in no namespace (rather than in a 'default
namespace').

Cheers,

Jeni
