Hello,
I have a bit problem trying to get specific sub-parent from XML and parse it as separate XDocument.
For example here is the hole XML:

XML

<?xml version='1.0' encoding="UTF-8" standalone="no"?>
<OPS_envelope>
    <header>
        <version>0.9</version>
    </header>
    <body>

                                        <item key="org_name">Example Inc.</item>
                                        <item key="phone">+1.4165550123x1812</item>

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:

C#

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(); 
}
