Since we're passing this into the shell, I think we should do paranoid validation on the 'chain' and 'ifname' fields, since they ultimately come from the user specified XML. Validate that it only contains a-Z, 0-0, -, _ It would also be nice to put a variety of XML files in a tests/nwfilterdata directory and making a test suite to run the parser API against them, as well as adding some real world examples in the examples/nwfilter directory for end users to start from.
