You might find ASIS2XML[1] helpful (it doesn't attempt to retain
comments, and really only retains textual information (that is, it
retains the name in an entity reference but not the links to the
referenced entity). Also, could do some cleanup of compound identifiers
- it retains the ASIS structure; so "with Ada.Characters.Handling;"
becomes

      <with_clause>
        <selected_component>
          <selected_component>
            <identifier>Ada</identifier>
            <identifier>Characters</identifier>
          </selected_component>
          <identifier>Handling</identifier>
        </selected_component>
      </with_clause>

Also Avatox[2].

The ASIS GPL 2014 source distribution contains a tool gnat2xml which
doesn't appear to be installed automatically. I didn't like the schema
very much, can't remember why now!

You'd probably use xslt to work with the generated XML.

    tools/gnat2xml for READMEs; I have a copy of avatox-1.8.tgz if you
    want.
