no relationship of type ... in collection error

Hi, I was trying python-docx with a .docx file which I got from a .doc file 'Saved as' a Strict Open XML Document with Microsoft Office Standard 2013. Unfortunately, when I'm trying to open the .docx file with python-docx, I get the error below. Does anybody have any idea what the problem is ?

Traceback (most recent call last):
  File "fillin_subrep_contract.py", line 39, in <module>
    fillin_contract_docx(sys.argv[1])

I expect you'll see a difference in the .rels part of the document package. I expect it uses a different URI for the main document relationship. If you dump the .rels part with opc-diag you should be able to see it.

If you do that on a regular Word document you get something like this:

$ opc browse default.docx .rels
<?xml version='1.0' encoding='UTF-8' standalone='yes'?>

  <Relationship Id="x" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/officeDocument" Target="word/document.xml"/>

</Relationships>

The second relationship item is the one python-docx is looking for to start the "open" process. Apparently there's change in there somewhere when saving as strict OpenXML.

@scanny

Thanks @scanny, my bad for using a 'Strict Open XML Document'. Re-generated my input document as a standard 'Word document' .docx and that seems to have fixed the problem.

Closing as resolved.

i have same issue , could you have other way using the python-docx to open the docx when saving as the strict open xml ？
