Hi Gururaj,
Chk this below code , u will get an idea how to get
<orders>
  <order id="1">
    <suborders>
      <order id = "2"/>
    suborders>
  order>
orders>
If we execute the following piece of code…

XDocument xDoc = XDocument.Load("orders.xml");
XElement[] xResultWithElements = xDoc.Root.Elements("order").ToArray();      XElement[] xResultWithDescendants = xDoc.Root.Descendants("order").ToArray();

xResultWithElements XElement array will contain 1 item and the xResultWithDescendants XElementarray will contain 2 items
Because the .Elements property look for elements only at the XElement being searched children nodes, meanwhile .Descendants traverse all of the xml markup looking for matching nodes starting from the XElement being searched.
If it helps you, do not forget to mark it as accepted.

Except not all ways can read XML with an "unlimited child depth". That sounds like a poorly designed format. Hierarchical data is not stored that way unless someone does not know how else to do it. I assume that a schema cannot represent an "unlimited child depth".

Do you have a schema for it or can you create a schema?

Hi Please see this Code Snippet for reading the XML

XmlNodeList elemList = doc.GetElementsByTagName(...);     for (int i = 0; i < elemList.Count; i++)     {         string attrVal = elemList[i].Attributes["SuperString"].Value;     }
