You can create an instance of XQuery, and then call
the parseFile method.  That returns a Compilation state.
Calling getModule on the latter gives you an abstract
syntax tree of the parser.  However, it's not fully
abstract - it is tailored to the Kawa compilation
framework.

You can use the flag --debug-print-expr to print the
parsed tree from the Kawa commmand line:

  kawa --xquery --debug-print-expr -C source-file.xql

That is an easy way to look at the structure of the tree.
