I have read the project description, and i understand what you need. However you forgot to upload the example files. I would appreciate if you could send them to me, so i can be sure my bid is accurate, thanks in advance. Something about me: i have strong knowledge of XML and XSLT, and i also know the command line utilities you mentioned, so it won't be a problem achieve this. If you have any question or more information, please don't hesitate to contact me by private message, thanks.
