This feature is provided in Word 2003 and later.
Click on File - Save as...
And then select xml document in the file type.
Thanks but i know that feature, but i have to upload that document to website, and then people has to download, and the style sheet i would be using would be same for uploading and downloading, I know that there are converters in the market but when i convert from word into XML, word take its own style sheet, but i have to give my style sheet which the company has same for everybody.
Please how to resolve this.
