Examples
The following example displays all the book titles.
#using <System.Xml.dll>
using namespace System;
using namespace System::IO;
using namespace System::Xml;
using namespace System::Collections;
int main()
{
XmlDocument^ doc = gcnew XmlDocument;
doc->Load( "2books.xml" );
//Get and display all the book titles.
XmlElement^ root = doc->DocumentElement;
XmlNodeList^ elemList = root->GetElementsByTagName( "title" );
IEnumerator^ ienum = elemList->GetEnumerator();
while ( ienum->MoveNext() )
{
XmlNode^ title = dynamic_cast<XmlNode^>(ienum->Current);
Console::WriteLine( title->InnerText );
}
}
using System;
using System.IO;
using System.Xml;
using System.Collections;
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");
IEnumerator ienum = elemList.GetEnumerator();
while (ienum.MoveNext()) {
XmlNode title = (XmlNode) ienum.Current;
Console.WriteLine(title.InnerText);
}
}
}
Imports System.IO
Imports System.Xml
Imports System.Collections
public class Sample
public shared sub Main()
Dim doc as XmlDocument = new XmlDocument()
doc.Load("2books.xml")
'Get and display all the book titles.
Dim root as XmlElement = doc.DocumentElement
Dim elemList as XmlNodeList = root.GetElementsByTagName("title")
Dim ienum as IEnumerator = elemList.GetEnumerator()
while (ienum.MoveNext())
Dim title as XmlNode
title = CType(ienum.Current, XmlNode)
Console.WriteLine(title.InnerText)
end while
end sub
end class
The example uses the file 2books.xml
as input.
