XmlDocument.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
)
public XmlNodeList GetElementsByTagName (
	String name
)
public function GetElementsByTagName (
	name : String
) : XmlNodeList
Not applicable.

Parameters

name

The qualified name to match. It is matched against the Name property of the matching node. The special value "*" matches all tags.

Return Value

An XmlNodeList containing a list of all matching nodes. If no nodes match name, the returned collection will be empty.

The nodes are placed in the order in which they would be encountered in the document.

NoteNote:

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

The following example creates a XmlDocument object and uses the GetElmentsByTagName method and the resulting XmlNodeList object to display all the book titles.

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

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

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

  }
}

import System.*;
import System.IO.*;
import System.Xml.*;

public class Sample
{
    public static void main(String[] args)
    {
        //Create the XmlDocument.
        XmlDocument doc = new XmlDocument();
        doc.Load("books.xml");

        //Display all the book titles.
        XmlNodeList elemList = doc.GetElementsByTagName("title");
        for (int i = 0; i < elemList.get_Count(); i++) {
            Console.WriteLine(elemList.get_ItemOf(i).get_InnerXml());
        }
    } //main
} //Sample

The example uses the books.xml file as input.
