[Solved] Avoid SAXException dialog with OLE pywin32

[Clorel]

I use this python script to convert my file DOCX to PDF with pywin32 in my LibreOffice 7.4.1.2 on Windows 10:
I set a argument for RepairDialog at True, but don't skip the dialog. Do you see, why ?

    main()

If you can't stop the dialog appearing you should at least be able to dismiss it without human intervention. I don't know python - If necessary an external program like Autoit might be able to do it. Or you could write your own executable in any language that waits for the window appearing then sends key strokes or a mouseclick to dismiss it.

Hi,

the MediaDescriptor passed to the loadComponentFrom Url function allows to specify an XInterActionHandler https://www.openoffice.org/api/docs/com ... ionHandler. Unfortunately, this handler is not called for SAXExceptions.

You probably can go the way JeJe describes. I may also be possible with LO internal programming, but is a lot of work. If you have many corrupt documents you may want to try it. Please note that the importer skips all document content after the first error, which in your case is in the header. If you are interested in more of the docx content, you should try to unzip the docx and repair it by hand

Good luck,

P.S. it is

Code: Select all

storeToURL

not

Code: Select all

storeToUrl

The presented dialog box is triggered by exception handler build into OpenOffice Python framework.
Python has ability to handle exceptions using try / except and raise clauses.
However, it this case it seems that at least one among xml files inside docx bundle cannot be parsed by SAX handler. It is interesting, why.
