I found a solution. By help from one guy from stacoverflow we create function that is getting the specific part of the XML as string.
Here is the solution:
I found a solution. By help from one guy from stacoverflow we create function that is getting the specific part of the XML as string.
Here is the solution:
public string ExtractItem(string response, string key)
{
var xmlDoc = XDocument.Parse(response);
var element = xmlDoc.Descendants("item").FirstOrDefault(i => i.Attribute("key").Value == key);
return element.ToString();
}
