Gets the number of nodes in the XmlNodeList.
public:
abstract property int Count { int get(); };C#
public abstract int Count { get; }member this.Count : intPublic MustOverride ReadOnly Property Count As IntegerThe number of nodes in the XmlNodeList.
The following example creates a XmlDocument object and uses the GetElementsByTagName method and the resulting XmlNodeList to display all the book titles.
#using <System.Xml.dll>
using namespace System;
using namespace System::IO;
using namespace System::Xml;
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" );
for ( int i = 0; i < elemList->Count; i++ )
{
Console::WriteLine( elemList[ i ]->InnerXml );
}
}
C#
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);
}
}
}
Imports System.IO
Imports System.Xml
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 i as integer
for i=0 to elemList.Count-1
Console.WriteLine(elemList.ItemOf(i).InnerXml)
next
end sub
end class
The example uses the file 2books.xml as input.
