[sword-devel] Android SWORD

[Martin Denham]

Hi,

I must confess that to make JSword perform a little better and due to lack
of xslt support on early versions of Android I tweaked jsword OSIS
processing so as to use OSIS XML -> SAX processor -> HTML.  I thus removed
jdom and xslt.  I realise there are various arguments for using jdom and
xslt but performance was my main driver on such small, low powered mobile
phones.

I may switch back to using xslt in the future because there is a lot of
logic in the xslt stylesheet that was difficult to reproduce in SAX.  Also,
now, I think I may have been able to get xslt going on old Android s/w but
am putting my effort into other areas.

Jdom may add too much overhead for such intense processing on small devices
although it works great on pcs.

Best regards
Martin
