ODT Read Format Error

[regebro]

We get an error when opening a document we have rendered, but I can’t understand what the error is.

I’ve managed to make a minimal content.xml to demonstrate the error, Removing any of the two <text:p/> tags fixes it, and also not declaring the sub-table as a subtable seem to fix it, but removing the texts would remove content in the actual doc, and not declaring the sub-table as a subtable seems wrong?

Any feedback or ideas on this are appreciated.

Please attach a computer-ready sample. This will be easier than entering it manually.

[regebro]

@ajlittoz , OK, uploaded

[ajlittoz]

Got same error. Row 23, col 1 corresponds to end of file.

For ease of further analysis, can you attach the same file as .fodt (provided of course you didn’t fully generate it by hand from scratch)?

[regebro]

@ajlittoz Well, I pretty much did, but replacing the <office:text> but with the failing example didn’t take long.
docdebugfodt.odt (26.6 KB)

I renamed it to odt here, otherwise I could not upload it.

[ajlittoz]

This is what I come up:

• unchanged, the file cause “general I/O error”
• commenting bot empty paragraphs, OK
• adding one character innermost paragraph as <text:p>a</text:p>, OK
• uncommenting second empty paragraph or adding a character inside id, “general I/O error”
  
  I am not skilled enough in XML internals to tell why this occurs. Have you created the file in XML or is this a slimmed down version of some problematic real file?

[regebro]

It’s a slimmed down version of a real file.

[ajlittoz]

Then do you remember what you changed between the last stable version and the first occurrence of the problem?

[regebro]

Yes, but that doesn’t tell me why the above XML doesn’t work, which is what I want to know, so I can go about fixing it. The alternative is to just try stuff randomly and see what works, and that will probably take a long time.

[regebro]

@ajlittoz To clarify: That’s a slimmed down version of a real file. That file is not generated by Libreoffice Writer but by other tools.

[ajlittoz]

Which other tools? They may be the culprit. ODF is rather subtle.

[regebro]

In house tools. Of course they are the culprit. I need to fix them.

[ajlittoz]

Then your question is not about Writer usage. It is rather about the ODF XML specification. I am not versed enough in it ti be of any help. Sorry.

[regebro]

No worries.
