Hey,

it will help if you write how are you writing to the file today.

anyway, this is a problem that can be solved (if not elegantly then
with force) and by force I mean that an XML file is a txt file first..
and if you know what you want to write you can always just insert it as
text.

An XML file is required to have only one top-level element. So no, you
can't just append to it. But you can read the file, append children to the
document element, and write it out again.

Roughly something like

       DocumentBuilder p = doSomethingToGetDocBuilder();

       Document doc = p.parse( new
               InputSource( new URL( FILENAME ).openStream(  )));

       while ( newData.hasMoreElements())
       {
               Element elt =
                       doSomethingWithNewData( newData.nextElement( ));

               doc.getDocumentElement().appendChild( elt);
       }

       domPrinter.print( doc, System.out);

3 different approaches:

1)  read in the entire XML file, append elements and
    rewrite the entire XML file

2)  keep the XML file invalid by missing the last end tag,
    simply append lines to the file, spoof the missing end
    tag whenever reading the file

3)  use a non portable trick by overwriting the last end tag
    with the new elements and an end tag using RandomFileAccess

I have some (not particular great) code illustrating all 3
approaches.
