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 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);
     } 

  }
}
#using <mscorlib.dll>
#using <System.Xml.dll>
using namespace System;
using namespace System::IO;
using namespace System::Xml;

int main()
{
     XmlDocument* doc = new XmlDocument();
     doc->Load(S"2books.xml");

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

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