You did not provide the xml file. However the answer is simple.

Just use Linq to Xml and parse the file to get the value in version and whatever elements you need.

string xml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><SampleFile><version>1</version><SomeData>Hello World</SomeData></SampleFile>";

XDocument document = XDocument.Parse(xml);

string versionValue = document
    .Descendants("version")
    .Select(i => i.Value.ToString())
    .FirstOrDefault();

Console.WriteLine("The version is {0}", versionValue);

There was a comment which I think meant reading the xml document from a url. You should be able to use the XDocument.Load method.

This will work and pull an xml doc I found from a Google search at this location.

//var document = XDocument.Parse(xml);
var document = XDocument.Load("http://producthelp.sdl.com/SDL%20Trados%20Studio/client_en/sample.xml");


var versionValue = document
    .Descendants("version")
    .Select(i => i.Value.ToString())
    .FirstOrDefault();

Console.WriteLine("The version is {0}", versionValue);
