An awesome job, it must've been quite the feat (I'm a programmer, I'd know ;) I've actually been working on an eBook version of QXP and just finished the "beta" version of it (will be posting it right after this). It still has some minor errors like punctuation errors, etc. but it might be helpful for your app. I noticed that your app cleared the formatting of the original text, things like italic and bold text. I know first hand how difficult it is to maintain the formatting of the original text, but since I was trying to create a faithful eBook copy of the original, I had to go through the motions and preserve the formatting. Anyway, in the process of building it, I've broken it up into header, footer, chapters, chapter headers, verse numbers, verse bodies and verse comments and will begin the process of putting it all in a database.
If you're familiar with MySQL and feel this is something you can use, then just send me a request at firstname.lastname@example.org.
