[basex-talk] XQuerry Help on Collections

I'm struggling a bit with XQuery especially in terms of collections. How would one take q query like for $x in doc('src/main/resources/xml/input.xml')//li return data($x) and apply it to a database with a collection of documents? What I'm after is something like: for $x in doc(*)//li return data($x) Also how are namespaces referenced/specified in queries? Finally if anyone as any good XQuery resources would appreciate if if you could pass them along...
