Xml Parsing in dot net

I have an xml file like this
<REGISTRATION>
<MAC_ID V='1ASD2345'/>
<LOCAL_IP V='192.08.20.04'/>
<PUBLIC_IP V='192.168.10.04'/>
</REGISTRATION>
and a class GatewayRegistration with
Public string MacId{},
public string LOcalIp{}

I have to read this xml file and store in object of that class using XMLDOcument.

I have tried in different way but not able to get the correct solution.So help me to parse this xml.
