Hi,
You can try something like this:
nNodes = root.childNodes.length;
// Generate random number
var nRand = Math.floor(Math.random() * nNodes) + 1;
var node = root.selectSingleNode("logo[" + nRand + "]");
Although above code is in javascript you can easily convert it to C# OR VB.NET

Hope this helps.
Thanks and Regards.
