Answer 1

XElment.Parse only use in String with single root node. The instance you wrote have two nodes '' without one root node. You can add a root node like below:

xml = "<root>" + xml + "</root>";

Answer 2

Using LINQ to XML should be easier:

var res = XElement.Parse(xml)
                  .Descendants("sentence").Where(e => e.Attribute("id").Value == "s0")
                  .FirstOrDefault().Value;

or, as Yeldar suggested, the cleaner way would be:

var s0 = XElement.Parse(xml)
                 .Descendants("sentence").FirstOrDefault(e => e.Attribute("id").Value == "s0")
                 .Value;
