Example
This example finds the root element.
This example uses the following XML document: Sample XML File: Multiple Purchase Orders (LINQ to XML).
XDocument po = XDocument.Load("PurchaseOrders.xml");
// LINQ to XML query
XElement el1 = po.Root;
// XPath expression
XElement el2 = po.XPathSelectElement("/PurchaseOrders");
if (el1 == el2)
Console.WriteLine("Results are identical");
else
Console.WriteLine("Results differ");
Console.WriteLine(el1.Name);
Dim po As XDocument = XDocument.Load("PurchaseOrders.xml")
' LINQ to XML query
Dim el1 As XElement = po.Root
' XPath expression
Dim el2 As XElement = po.XPathSelectElement("/PurchaseOrders")
If el1 Is el2 Then
Console.WriteLine("Results are identical")
Else
Console.WriteLine("Results differ")
End If
Console.WriteLine(el1.Name)
This example produces the following output:
Results are identical
