Here you define the default namespace as "http://gitk.sourceforge.net/";

Therefore, element "widget" belong to namespace "http://gitk.sourceforge.net/";

And here you are asking for elements with localname "widget" and WITHOUT namespace (I think that XPath 
doesn't have the concept of default namespace, you always need to specify a prefix like "mynsprefix:widget")

And xmllint gives you the right answer.

I don't know how to use the shell xpath command in documents with declared default namespaces, since the 
shell utility doesn't have a command to register namespaces and prefixes (something like xmlXPathRegisterNs).
