[jsword-devel] Fwd: [sword-devel] Tables across verse boundaries

Yup - so I was looking at the code tonight.

I don't think the problem is quite as bad/hard to fix as you make it sound.

I think there are two types of issues
- a verse on its own not producing correct XML
- a bunch of XML together not producing well nested XML

Not sure how to solve the second, but the easy (?) solution on the second
one is to amalgamate all the raw text first before parsing it. Now that we
pass the whole passage down one more level, it shouldn't be too difficult
to do that?

On the second, there may some nice XML parsers that fix stuff up more
gracefully as well...

1- You're right, it was my mistake around across verses. Ezra 1 would be an
example where you have 3 rows per verse, and a table over two verses.

No problem. It's hard to debug a problem where the text is made up.

2- My issue with the markup and having the verse number inside the cell was
that I got a 'nesting' warning by mod2osis. Is that something i just
ignore? (i.e. "verse sID" in the first cell with "verse eID" in the second

The nesting warnings are relatively benign. They indicate that the verse in
isolation is not well-formed XML and that when displayed in certain
contexts it will have problems.

That the verse sID is in one cell and the verse eID is in another by itself
is not a problem. It is more a question if the raw data from the module is
a well-formed fragment.

3- I had another look at the output, and the module does in fact have the
table in it. It looks like it wrapped it into verse 8, as expected. So it
seems, that maybe this is an issue specific to JSword?

It is a particularily bad problem with JSword. JSword passes the verse raw
data to an xml parser to create an xml fragment, which it fails when not
well-formed. When the exception is caught, we then strip all markup out of
the raw data and re-parse it.
This is particular to JSword.

However, when the verse is shown in isolation by any SWORD frontend or in a
table cell, it most likely will not display as intended. It's that JSword
does it one worse. If we wish to discuss JSword's shortcoming more, we
should do that on jsword-devel or create an issue for it (if there isn't
already one, as we have talked about this problem in the long past.)
