Can I put XP and Microsoft Word on my IPad ?
No and no.
but you can use remote desktop apps such as teamviewer to display and operate a computer over the network on the ipads screen
Since you now know that you can't run either of them on an iPad that leads me to the question why would you want to do that anyway?
Maybe if we know what you hope to gain by this we might be able to suggest other solutions for you to get what you need.
