XmlDocument.LoadXml Method

Loads the XML document from the specified string.

Namespace:  System.Xml
Assembly:  System.Xml (in System.Xml.dll)
public virtual void LoadXml(
	string xml
)

Parameters

xml
Type: System.String
String containing the XML document to load.
Exception Condition
XmlException

There is a load or parse error in the XML. In this case, the document remains empty.

By default the LoadXml method does not preserve white space or significant white space.

This method does not do DTD or Schema validation. If you want validation to occur, you can create a validating XmlReader instance by using the XmlReaderSettings class and the Create method. For more information, see Validating XML Data with XmlReader.

If you want to load from a Stream, String, TextReader, or XmlReader, use the Load method instead of this method.

This method is a Microsoft extension to the Document Object Model (DOM).

The following example loads XML into an XmlDocument object and saves it out to a file.


using System;
using System.Xml;

public class Sample {

  public static void Main() {

    // Create the XmlDocument.
    XmlDocument doc = new XmlDocument();
    doc.LoadXml("<item><name>wrench</name></item>");

   // Add a price element.
   XmlElement newElem = doc.CreateElement("price");
   newElem.InnerText = "10.95";
   doc.DocumentElement.AppendChild(newElem);

    // Save the document to a file and auto-indent the output.
    XmlTextWriter writer = new XmlTextWriter("data.xml",null);
    writer.Formatting = Formatting.Indented;
    doc.Save(writer);
  }
}

XmlDocument.LoadXml(string) cause of stream or socket exeptions and a long loading.

XmlDocument.LoadXml(string) try to load something extra if there are DOCTYPE in HTML and one can rise a stream and socket exeptions.
Silverlight 3 environment.

In case of the DOCTYPE the LoadXml also every time expected a very long loading (~3 min).
If you exclude the DOCTYPE from a XHTML/HTML and wish to use the GetElementById method, then use something like next extension-method:

public static XmlElement GetElementByIdInXml(this XmlDocument doc, String id)

{

constString QueryById = "//*[@id='{0}']";

return (XmlElement)doc.SelectSingleNode(String.Format(QueryById, id));

}
