How to import from an XML file?

I have an XML file of my posts only from an old SQL database (no longer have the SQL)… how do I convert this to a WXR?

I tried just importing it anyway, and it seemed to work, but the posts do not show up.

Here is what the file looks like…

<?xml version=”1.0″ encoding=”utf-8″ ?>
