If you have the Windows CD, insert it and follow the instructions. Delete the Linux partition(s) and follow through with the installation.
If you mean have Xp without deleting it. You should use a partition manager like Partition Magic and delete the Linux partition(s) from Windows.
I don't know if you can still boot Windows though. If it doesn't work, come back and we'll fix it.
Good Luck!
