How to parse epub files

Hi all,

I want to parse epub files in android. I referred epublib library files but not bale to parse using it.That library file is missing some classes. I use its source code too, but Dalvik is not able to build apk file because of some package name clash in javax.xml.stream package.

Is there any solution of this?

I use java's zip class to to unzip epub files. It unzips the file but takes lot of time for unzipping.

Or is there any other ready to use library to parse epub files.
Please help.
