[Solved] LibreOffice Format Error SAXParse

[hughd]

Another SAXParseException
I just spent an hour working on a .docx without intermittent saves. Using LivbreOffice 5.3.x because I find it easier then working in Word.
the final thing I did was try to bulk change character colour throughout the document from Chartreuse et al (God only knows why anyone chose that). Now it won't open with Word nor LibreOffice.
Finally I tried to open it again with both Word and with LO. and neither will open it.
The error message from the "expurgated" version from LibreOffice is:-
File format error found at
SAXParseException: '[word/document.xml line 2]: Attribute w:themeColor redefined
', Stream 'word/document.xml', Line 2, Column 76545(row,col).

The error message from the more original version (ending TNR) is:-
SAXParseException: '[word/document.xml line 2]: Attribute w:themeColor redefined
', Stream 'word/document.xml', Line 2, Column 81594(row,col).

I have limited time before I have to send this back to the committee for whom I am doing this edit.
Please help.

Please upload the earliest damaged version of the file so that someone can examine it.

Hi Rory
I tried attaching the files but they are both too big, 160KB and 170KB
I can't find a way to attach them in your web based email facility.
If you email me privately I can send them to you.
Cheers
Hugh

If they don't have confidential data, you could use a file sharing service such as dropbox. Alternatively, I've sent a PM with an email address.
