Differences between xdocument and xelement

When loading XML using the load method, you will find the difference between the two:

The following is a brief summary:

Xdocument. Load () load the entire XML file including the root node

Xelement. Load () does not load the XML Root Node

Xelement. Load () Sample Code:

File.WriteAllText("Test.xml", @"<Root>    <Child1>1</Child1>    <Child2>2</Child2>    <Child3>3</Child3></Root>");Console.WriteLine("Querying tree loaded with XElement.Load");Console.WriteLine("----");XElement doc = XElement.Load("Test.xml");IEnumerable<XElement> childList =    from el in doc.Elements()    select el;foreach (XElement e in childList)    Console.WriteLine(e);

Result:

Querying tree loaded with XElement.Load----<Child1>1</Child1><Child2>2</Child2><Child3>3</Child3>

Xdocument. Load () sample code:

File.WriteAllText("Test.xml", @"<Root>    <Child1>1</Child1>    <Child2>2</Child2>    <Child3>3</Child3></Root>");Console.WriteLine("Querying tree loaded with XDocument.Load");Console.WriteLine("----");XDocument doc = XDocument.Load("Test.xml");IEnumerable<XElement> childList =    from el in doc.Elements()    select el;foreach (XElement e in childList)    Console.WriteLine(e);

Result:

Querying tree loaded with XDocument.Load----<Root>  <Child1>1</Child1>  <Child2>2</Child2>  <Child3>3</Child3></Root>
