Hi,

I'm doing a cross platform project that requires a conversion of document to plain text. And i have to use that plain text for further processing. Are there any c++ libraries that can convert docx and odt file to text file? Are there any platform independent c++ libraries for conversion?

Thanks in advance.

Use word interop would be the obvious solution.

What is word interop? Could you explain about that?

I don't want to use Microsoft application instead i need a library that does the conversion in programmatic way. Also since i'm building a cross platform application i cannot depend on the Microsoft service for the conversion.

Maybe you should improve your "question" to include all of the information necessary for someone to help you.

I know where to get the code -- please see my answer.

Because both formats use XML files, you may unzip the archives, and pass the XML file containing the text content to a XML to text converter.

The keyword for such converters is XSLT. With Windows, you can use MSXML. With Linux (and also Windows) you can use libxslt/libxml2. However, there are also other libraries.

With .NET, you can use System.Xml.XmlReader.

Good answer, (would be) my +5 if I could.

Thank you. But there is still not enough information to give a final solution.

With Linux I'm actually doing something similar (output is HTML) using two small perl scripts that do the extraction and call xsltproc.

Sergey Alexandrovich Kryukov 12-Oct-12 12:54pm

That's true, but XML in not the issue, the issue is the semantic level of data. The code is available as open-source -- please see my answer.

Thanks Alex, i have browsed through the code of libre office, but i can't find which part does the conversion. Could you please tell me?

Sergey Alexandrovich Kryukov 15-Oct-12 1:40am

If you are trying to talk to me, I've never been "Alex".
The code is big, I cannot help you to find the fragment you need at this time. It needs considerable amount of time to find out. Start from building of the whole project and using export from docx, doc or odt files.

I understand that you don't want to use any proprietary software like Microsoft Office and why. The only open-source code I know is OpenOffice itself (where .odt came from) and its fork LibreOffice. Please see:
http://en.wikipedia.org/wiki/OpenOffice.org[^],
http://www.openoffice.org/[^],
http://en.wikipedia.org/wiki/LibreOffice[^],
http://www.libreoffice.org/[^].

You can download the source and find the code working with nearly all versions of Office documents. And, of course, .ODT and all other OpenOffice/LibreOffice documents.

Interesting collection of links, my 5!

Sergey Alexandrovich Kryukov 12-Oct-12 13:42pm

Thank you, Maciej.
Not really a collection; this is about just one product, essentially; the only code I know which readily works with all those formats directly, without any proprietary software.

Maciej Los 12-Oct-12 13:50pm

Formally... 1 link is not a collection, but 2, 3 and more links is a collection... although one product ;)

Sergey Alexandrovich Kryukov 12-Oct-12 14:47pm

OK, this is a collection of two: OpenOffice and LibreOffice, the second being the split of first. Well, collection of two. Formally. :-)
Thank you.

Maciej Los 12-Oct-12 14:52pm

He-he ;) We are the collection of two... formalist ;)

Sergey Alexandrovich Kryukov 12-Oct-12 15:08pm

I'm just followed your lead.., formalist. :-)
