I agree that this is largely a guess, but there is one relatively simple heuristic that might actually help this case. Well-formed XML documents may nest tags, but can't have an inner tag close after the enclosing tag. For example: 

<document><text>Some text</text></document>  <!-- Valid   -->
<document><text>Some text</document></text>  <!-- INVALID -->

So, an algorithm that makes sure nested tags are closed before the enclosing tags is a good step, and if the sample above is representative such a step will likely go a long way toward solving the problem.
