Yup - except that the HTML export filter is awful (C) code, which I haven't yet got
around rewriting since I inherited it.

In fact the closest filter (that is, one that uses QDom), would be the old version
of the CSV filter, whose code you can find in koffice/filters/kspread/csv/cvsexport.cc
line 177.

Then of course you'll need to look at the KWord DTD, available under
koffice/kword/dtd/kword.dtd, to know what tags to expect and parse.

Documentation and pointer to template are available at http://www.koffice.org/filters/tutorial.html
Estimate is: this depends pretty much on how fast you master Qt and QDom, but on the whole
it really shouldn't take you long.
