You can use an external variable to specify a filename/URL.
Thus in script.xql:

declare variable $input external;
doc($input)

Then invoke it thus:

java kawa.repl --xquery input=file.xml script.xql

You need a fairly recent version of Qexo (I suggest the just-announced
release candidate of 1.8) to be able to use extenal variables.
