IE6:clientside - XML to string?

Sorry for the OT post, but it seems like this is the best place to ask the
question...

Is it possible given the following in on an html page:

<XML id="source" src="abc.xml"></XML>

to get the a string representation of the xml from some DOM method using
javascript?  (I am having troubles finding documentation at MS for IE6 which
is in beta)
----------------------------
If abc.xml was:

<article>
  <para> blah blah</para>
</article>
---------------------------
then is there something like?

var theXMLasString= source.toString()

which make this true:

theXMLasString=='<article>\n%20%20<para> blah blah</para>\n</article>';
// or whatever the proper string notation is...

thanks for any help or pointers,
Rob
