<div>Douglas, here is a quick overview of And Bible's approach:</div><div><br></div>And Bible gets the raw content of a page from the book by using <a href="https://github.com/mjdenham/and-bible/blob/master/AndBible/src/net/bible/service/format/OSISInputStream.java">OsisInputStream</a>, and feeds it into an <a href="https://github.com/mjdenham/and-bible/blob/master/AndBible/src/net/bible/service/format/osistohtml/OsisToHtmlSaxHandler.java">OsisToHtmlSaxHandler</a> that converts OSIS tags to HTML and any other changes required.

<div><br class="Apple-interchange-newline"></div></div><div>To improve performance there is no DOM tree created in the above process. All xml manipulation is done in the SAX handler or helper classes. This approach might be a bit lightweight for a general framework like JSword but worked well for And Bible's requirements.<div>
<br class="Apple-interchange-newline"></div><div>And Bible does not use the optimised approach for non-OSIS documents for which the XXXFilter classes, e.g. GBFFilter, in JSword are required to convert the XXX format to OSIS tags. And Bible's approach could be extended to chain together SAX Filters to incorporate the code in XXXFilter classes.</div>

Howdy!<br>
<br>
I was talking with DM wrt removing jdom and using org.w3c.* APIs instead (more portable, less deps), and he asked me to post it here :)<br>
<br>
Any objections? (I'm assuming I'll fix BD too)<br>
