XML Parsing in JAVA and JAXB

The work is to write a java code to parse a series of XML files; all are of the same standard format ( TEI; Text Encoding Initiative). The code should iteratively select a file, use JAXB to parse it and save the result in a CSV format. These XML files are the direct output of a Java binding called 'GROBID' that you can further read about it in the following link ([login to view URL]). In their documentation, they have suggested JAXB 2 and above. I expect the whole work to take no more than 2-3 hours, but that's my initial guess, what do you think? Can you possibly assist? I have done a simple java code as a test (not with JAXB) and was able to do simple parsing, but I need a more advanced parser to be able to get what I need from each XML). I would appreciate if you could share your thoughts on this with me. You can see a sample of the inputs in my dropbox folder:[login to view URL] Kind Regards Matt.
