That is what I did when I wrote DOMParser back in SAX1 days.  But SAX2
has a standard pattern for tree-walking SAX parsers: the parse() methods
ignore their parameters, and one specifies the tree object with setProperty
(String magicURI, nu.xom.Document doc).

SAX2 defines the standard property URI for the DOM tree to walk as
http://xml.org/sax/properties/dom-node, so I would think that
http://xom.nu/properties/xom-node would be a suitable URI for XOM.

Implementation note:  When I wrote DOMParser, I was careful *not* to
use recursion, because there would be no guarantee that the Java stack
wouldn't blow up.  Instead I used the incremental version of walking
the whole tree:

        1) firstChild, unless null, in which case
        2) nextSibling, unless null, in which case
        3) parent() and try again, unless root, in which case
        4) stop.
