I'm createing a program which needs saving data about for example version numbers. I will use an XML file to do so. The problem is that I'm rather new to C# Programming and I need some help with how to read an element from the XML file, read an element from another and then compare the number between the version elements. The program will then give one of the following messages:

"Application is up to date"
"There's a new version available for download"

I use .Net 3.5
