Docx extract media as original filenames

Docx extract media as original filenames

Hello everyone!

I want to covert a docx to a docbook file with --extract-media, so i can 
upload the pictures automatically into a database.
Is there any "hack" to keep the original filename for the extracted 
picture's name + imegaobject fileref's value?

For example...
I have a file what has been pasted into the docx file with this name -> 
picture_upload.png. I want to extract into the /media folder as 
'picture_upload.png', and set the docbook's imegamedia fileref's value to 
'picture_upload.png' or './media/picture_upload.png'.

In the <file>/word/document.xml there is this block, what contains the 
original filename:
<pic:pic xmlns:pic=
"http://schemas.openxmlformats.org/drawingml/2006/picture">
    <pic:nvPicPr>
        <pic:cNvPr id="0" name="picture_upload.png"/>
            <pic:cNvPicPr/>
     </pic:nvPicPr>
     <pic:blipFill>
         <a:blip r:embed="rId21"/>
             <a:stretch>
                 <a:fillRect/>
             </a:stretch>
      </pic:blipFill>
      ...


Its reference is in the <file>/word/_rels/document.xml:
Target="media/image110.png"/><Relationship Id="rId21" Type=
"http://schemas.openxmlformats.org/officeDocument/2006/relationships/image"

And the docbook output is:
<imagedata fileref="./media/image110.png" />

The file's name in the './media' folder is the same as the "Target" value.

Any idea will help :)
Thank you.

Here's the problem. Let's say you have two files named "pic.jpg":
"~/pics/pic.jpg" and "~/Downloads/pic.jpg." They would *both* show as
having "pic.jpg" in their name field. Or maybe you added one, and then
added another later on a different computer. In any case, that name
attribute isn't dependable. I'm not sure if it's even required. Without
looking at the spec, I'm also not sure whether the characters in it are
guaranteed to be legal for a filename. (And that's not even going into
the issue of going from a case-sensitive FS to a case-insensitive one.)

Seems I suppose it's possible to do it by sanitizing and then adding numerical
suffixes if there's a collision. Seems like it might be a can of worms,
though, and it would probably create inconsitencies with other
input formats.

Best,
Jesse

Thank you for the reply!

The main problems are with the docbook's fileref's value.
Here is the complete example what i want to do:
1. Upload a bunch of docx file, convert into a docbook, because my db's 
main content is a docbook file.
2. Save the converted file with the images into a database.
3. Convert the docbook again to a html, when the user wants to read it in a 
browser.

Because the images are in the same database, the final <img> tag's "src" 
attribute's - with a little modification - will be this: 
http://.../rest/<file's identifier>.
In this case it's possible to show a complete html content in the main 
webapplication, without copy the source images into it, and if I can't 
change the extracted filenames
(maybe with a prefix), there are going to be a lot of files in the database 
what's name is just "image1". The second problem, if i want to update a 
picture, i won't know
which one is it.

Guys,

Is there any update regarding prefix the image names or change it somehow?

Thanks,
