XElement.Load Method (XmlReader)


Loads an XElement from an XmlReader.

Namespace:   System.Xml.Linq
Assembly:  System.Xml.Linq (in System.Xml.Linq.dll)

public static XElement Load(
	XmlReader reader


Type: System.Xml.XmlReader

A XmlReader that will be read for the content of the XElement.

Return Value

Type: System.Xml.Linq.XElement

An XElement that contains the XML that was read from the specified XmlReader.

By creating an XmlNodeReader from a DOM document, and then using the XmlNodeReader to create an XElement, this method can be used to create a copy of a DOM document in a LINQ to XML tree.

LINQ to XML's loading functionality is built upon XmlReader. Therefore, you might catch any exceptions that are thrown by the XmlReader.Create overload methods and the XmlReader methods that read and parse the document.

The following example creates a DOM document, creates an XmlNodeReader from the DOM document, instantiates a tree from the reader. This code effectively copies a DOM document into a LINQ to XML tree.

// Create a DOM document with some content.
XmlDocument doc = new XmlDocument();
XmlElement child = doc.CreateElement("Child");
child.InnerText = "child contents";
XmlElement root = doc.CreateElement("Root");

// Create a reader and move to the content.
using (XmlNodeReader nodeReader = new XmlNodeReader(doc)) {
    // the reader must be in the Interactive state in order to
    // Create a LINQ to XML tree from it.

    XElement xRoot = XElement.Load(nodeReader);

This example produces the following output:

  <Child>child contents</Child>
