XmlNamedNodeMap.Item(Int32) Methode

Definition

Ruft den Knoten am angegebenen Index in der XmlNamedNodeMap ab.Retrieves the node at the specified index in the XmlNamedNodeMap.

public:
 virtual System::Xml::XmlNode ^ Item(int index);
public virtual System.Xml.XmlNode Item (int index);
abstract member Item : int -> System.Xml.XmlNode
override this.Item : int -> System.Xml.XmlNode
Public Overridable Function Item (index As Integer) As XmlNode

Parameter

index
Int32

Die Indexposition des aus der XmlNamedNodeMap abzurufenden Knotens.The index position of the node to retrieve from the XmlNamedNodeMap. Der Index ist nullbasiert. Daher ist der Index des ersten Knotens 0 und der des letzten Knotens Count -1.The index is zero-based; therefore, the index of the first node is 0 and the index of the last node is Count -1.

Gibt zurück

Der XmlNode am angegebenen Index.The XmlNode at the specified index. Wenn index kleiner als 0 oder größer oder gleich der Count-Eigenschaft ist, wird null zurückgegeben.If index is less than 0 or greater than or equal to the Count property, null is returned.

Beispiele

Im folgenden Beispiel wird die XmlAttributeCollection-Klasse (die von XmlNamedNodeMaperbt) verwendet, um alle Attribute eines Buchs anzuzeigen.The following example uses the XmlAttributeCollection class (which inherits from XmlNamedNodeMap) to display all the attributes of a book.

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
{
   XmlDocument^ doc = gcnew XmlDocument;
   doc->LoadXml( "<book genre='novel' publicationdate='1997'>   <title>Pride And Prejudice</title></book>" );
   XmlAttributeCollection^ attrColl = doc->DocumentElement->Attributes;
   Console::WriteLine( "Display all the attributes for this book..." );
   for ( int i = 0; i < attrColl->Count; i++ )
   {
      Console::WriteLine( "{0} = {1}", attrColl->Item( i )->Name, attrColl->Item( i )->Value );

   }
}

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

public class Sample
{
  public static void Main()
  {
     XmlDocument doc = new XmlDocument();
     doc.LoadXml("<book genre='novel' publicationdate='1997'> " +
                 "  <title>Pride And Prejudice</title>" +
                 "</book>");      
 
     XmlAttributeCollection attrColl = doc.DocumentElement.Attributes;

     Console.WriteLine("Display all the attributes for this book...");
     for (int i=0; i < attrColl.Count; i++)
     {
        Console.WriteLine("{0} = {1}", attrColl.Item(i).Name, attrColl.Item(i).Value);
     }         
    
  }
}
