Re: [opendocument-users] Fixing corrupted odt

["Jan Wildeboer" <jwildebo@redhat.com>]

The validators should give you a hint, I guess. To me it sounds as being 
some obscure tag problem. How did this start? Suddenly, while opening? 
Corrupted (crashed) save before? Backups available? Some weird graphics 
included?

Well, I think it is not overly sensitive, but the people who write tenders 
"tend" to disagree - I'll try and gently prise it out of their 
over-sensitive fingers tomorrow. After all, I guess no one on this list has 
a competing commercial interest in the archaelogical excavation of human 
remains...

I have got this far - namely you can delete/replace most anything in the 
within the file and still get the same error; delete/replace content.xml and 
file opens, though of course without content... Opening content.xml with an 
XML-aware application e.g. Kate ties it in knots, using all the spare CPU on 
a dual core laptop. Opening content.xml in OpenOffice as a plain text file 
and, following a tip on OpenOffice forum, deleting everything between the 
<office:automatic-styles> tag resulted in the same error; deleting 
everything between <office:body> got an opening document, though of course 
without (visible) content...
