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
)

Parameters

name
Type: System.String

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

Return Value

Type: System.Xml.XmlNodeList

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.

System_CAPS_noteNote

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

The following example creates a XmlDocument object and uses the GetElementsByTagName 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);
    }  

  }
}

The example uses the books.xml file as input.
