Re: docx to txt

[elef]

I just noticed you wrote docx2txt "could be a starting point, but I am having some difficulties to figure out how to integrate it into my application."

It seems pretty straightforwared to me, but here's what I did in case you need it: I just kept docx2txt in a separate file out of laziness and just used

system ("perl \"$pathtodocx/docx2txt.pl\" \"${infile}.doc\" \"${outfil
+e}.txt\"");

Now, my app needs to run on both *nix and Windows, and Windows compatibility required quite a bit of trickery. I modified the .pl slightly, bundled an unzip program with my application and wrote some code that generates a .config for docx2txt at runtime, to let docx2txt know where unzip.exe is. It's not what I would call elegant, but it works. If you need this to run on Windows computers other than your own, I can paste the code here.

system, autodie

I am back from some days of holidays ;)

Oh, I would really appreciate if you could post your solution!

I'm guessing that was directed towards me.
Apologies for not answering sooner, I just found this post now.

Anyway, here's the code (keep in mind that I'm by no means an experienced coder... also, this code was taken from a much larger project, so some of the silly variable names have a logic you can't see here. It's also missing some logging and reporting I left out etc. I have only tested this on Windows, but it's designed to work on most linux distros and OSX as well.):

Now, this requires docx2txt.pl for *nix, and docx2txt.exe and unzip.exe on windows. It looks for these in scripts/docx2txt, I have uploaded the necessary files here. Of course you can get your own unzip binary and generate docx2txt.exe yourself with pp, which is what I did, or just use the .pl on Windows as well if your users can be expected to have perl installed.
The file won't be up here for long, so here's a summary in case someone reads this when I've already yanked it:
Docx2txt needs to unzip the docx (zip) files. To make this work on Windows, I have modded the original perl script to use a different config file (docx2txt_win.config) which the main script generates at runtime, filling in the path to unzip.exe (scripts/doxc2txt/unzip) according to what folder it's in. Then I generated an executable (docx2txt_win.exe) out of this slightly modified script. On Linux and OS X systems, the original .pl is used without modifications as these OSes can reasonably be expected to have an unzip utility at usr/bin/unzip.
