You may use the System.Xml.Linq.XDocument:

//Initialize the XDocument
XDocument doc = XDocument.Parse(yourString);

//your query
var desiredNodes = doc.Descendants("PresentationElements");

You can use XPath extensions

var xdoc = XDocument.Parse(response);
XElement presentations = xdoc.XPathSelectElement("//PresentationElements");

Pretty easy, have you tried:

XDocument xml = XDocument.Load("... xml");
var nodes = (from n in xml.Descendants("PresentationElements")
                        select n).ToList();

You could also project each individual node to an anonymous type using something like:

select new 
{
  ContentReference = (string)n.Element("ContentReference").Value,
  .... etc
}
