xpath

What's the simplest API to use in scala to perform the following XPath queries on a document?

//s:Annotation[@type='attitude']/s:Content/s:Parameter[@role='type' and not(text())]

//s:Annotation[s:Content/s:Parameter[@role='id' and not(text())]]/@type

The only documentation I can find on Scala's XML libraries has no information on performing complicated real XPath queries.

I used to like JDOM for this purpose (in Java), but since JDOM doesn't support generics, it will be painful to work with in Scala. (Other XML libraries for Java have tended to be even more painful in Java, but I admit I don't know the landscape real well.)
