Copying Tables to New Database?

Hello

recently, my wordpress blog was hacked into and they might have messed up part of my mysql database (or added a script somewhere that won’t allow me to create a new instance of wordpress to access the current database)

Therefore, I have to start from scratch again. Is it possible however to copy all the posts and categories from the current damaged database and paste/import them into a fresh new database through phpmyadmin?

can someone provide step-by-step intructions to doing this.

thanks for the help

and god bless..
