定义

命名空间:

System.Xml

程序集:

System.Xml.dll, System.Xml.XmlDocument.dll

程序集:

System.Xml.ReaderWriter.dll

程序集:

System.Xml.XmlDocument.dll

程序集:

System.Xml.dll

程序集:

netstandard.dll

检索给定索引处的节点。

public:
 abstract System::Xml::XmlNode ^ Item(int index);

public abstract System.Xml.XmlNode Item (int index);

public abstract System.Xml.XmlNode? Item (int index);

abstract member Item : int -> System.Xml.XmlNode

Public MustOverride Function Item (index As Integer) As XmlNode

参数

index

Int32

节点列表中从零开始的索引。

返回

XmlNode

XmlNode 与集合中的指定索引. 如果 index 大于或等于列表中的节点数，则这返回 null。

示例

以下示例获取并显示第二个节点。XmlNodeList

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
{
   XmlDocument^ doc = gcnew XmlDocument;
   doc->LoadXml( "<items>"
   "  <item>First item</item>"
   "  <item>Second item</item>"
   "</items>" );
   
   //Get and display the last item node.
   XmlElement^ root = doc->DocumentElement;
   XmlNodeList^ nodeList = root->GetElementsByTagName( "item" );
   Console::WriteLine( nodeList->Item( 1 )->InnerXml );
}

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

public class Sample {

  public static void Main() {

     XmlDocument doc = new XmlDocument();
     doc.LoadXml("<items>" +
                 "  <item>First item</item>" +
                 "  <item>Second item</item>" +
                 "</items>");

     //Get and display the last item node.
     XmlElement root = doc.DocumentElement;
     XmlNodeList nodeList = root.GetElementsByTagName("item");
     Console.WriteLine(nodeList.Item(1).InnerXml);
  }
}

     Dim nodeList as XmlNodeList = root.GetElementsByTagName("item")
     Console.WriteLine(nodeList.Item(1).InnerXml)
