Getting Variables from XML in Visual Basic

I have a program which installs a list of programs. I want to have a config file to point to the location of each program.

<app1>C:\Test\App1.exe</app1>
<app2>C:\Test\App2.exe</app2>
<app3>C:\Test\App3.exe</app3>

I think this XML file should be read on Load and assign the location as a variable. Then I can assign the command process.start(AppXVariable) when a button is clicked.

Any help would be much appreciated

Thank you
