Using XML for High Score Table

Hello,

Needing a hand here making a high score table for a pong game i have created. Read a few different ways about it but it seems XML is the best way rather than just using a text file. Only problem is i don't know how to use XML. I have read a bit on Serialization and De-serialization but i'm not sure how to use them and the right code to do so.

At the moment when the game ends, it asks for the players name and has the players score in a variable.

How do i save their name and score and then load it up on a different form in a highest to lowest order?

Thanks in Advance
