XmlElement.GetElementsByTagName Method (String)

Returns an XmlNodeList containing a list of all descendant elements that match the specified Name.

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

public virtual XmlNodeList GetElementsByTagName(
	string name
)

Parameters

name
Type: System.String

The name tag to match. This is a qualified name. It is matched against the Name property of the matching node. The asterisk (*) is a special value that matches all tags.

Return Value

Type: System.Xml.XmlNodeList
An XmlNodeList containing a list of all matching nodes. The list is empty if there are no matching nodes.

The nodes are placed in the order in which they would be encountered in a preorder traversal of the XmlElement tree.

NoteNote

It is recommended that you use the XmlNode.SelectNodes or XmlNode.SelectSingleNode method instead of the GetElementsByTagName method.

The following example gets and displays all the book titles.

using System;
using System.IO;
using System.Xml;

public class Sample
{
  public static void Main()
  {
     XmlDocument doc = new XmlDocument();
     doc.Load("2books.xml");

     // Get and display all the book titles.
     XmlElement root = doc.DocumentElement;
     XmlNodeList elemList = root.GetElementsByTagName("title");
     for (int i=0; i < elemList.Count; i++)
     {   
        Console.WriteLine(elemList[i].InnerXml);
     } 

  }
}

The example uses the file, 2books.xml, as input.
