If XML is causing you problems, perhaps you should not be using it? In the end, you have to understand that XML is a hierarchical structure. You can't simply append data, it must be inserted at the correct level in the hierarchy. How difficult that is depends on the schema or DTD being used. It may be possible to simply chop off a couple of closing tags, insert your new data and restore the tags behind it. But again, the code needs to be smart enough to know which tags need to be where in order to insure the results are still well formed. If the file is too big, perhaps SAX is a better option that DOM.
