I think that this is fine.

I think that parse-xml will support what you are talking about. In terms of
the "check" that you are doing to see if a field exists or not before adding
another value for it in the index, as I understood Lucene, I believe that
you could just omit this check and add the field regardless. If you add
multiple values for the same field in a Document, e.g:
<snip>
Document doc = new Document();
doc.add(new Field("fieldname", "fieldvalue", ...));
doc.add(new Field("fieldname", "fieldvalue2",...));
</snip>
Both the values "fieldvalue" and "fieldvalue2" will both get stored in the
index for the key "fieldname". So, if I understand you correctly (which I
may not ;) ), then I think you can omit the check that you are talking about
above and just go with adding the same field name 2x.
HTH,
Chris
