                           // Selects all the title elements that have an attribute named lang

                           XmlElement root = doc.DocumentElement;
                           nodeToFind = root.SelectSingleNode("//OverDueStatus");
                           if (nodeToFind != null)
                           {

Use SelectNodes instead.
Make your XPath expression return both nodes.

XmlDocument.Load expects the path of an XML file to load. If your result variable contains the XML as a string, then you need to use LoadXml instead.

XmlDocument.Load Method (System.Xml) | Microsoft Docs[^]
XmlDocument.LoadXml(String) Method (System.Xml) | Microsoft Docs[^]

That worked.I need to get the node exists in the above xml string without looping.
Tried
XmlNode nodeToFind;
XmlDocument doc = new XmlDocument();
doc.LoadXml(result);

// Selects all the title elements that have an attribute named lang

XmlElement root = doc.DocumentElement;
nodeToFind = root.SelectSingleNode("//OverDueStatus");
if (nodeToFind != null)
{

}
