从 XmlNamedNodeMap 中移除指定的节点。

重载

RemoveNamedItem(String)	从 XmlNamedNodeMap 中移除节点。
RemoveNamedItem(String, String)	移除具有匹配的 LocalName 和 NamespaceURI 的节点。

RemoveNamedItem(String)

从 XmlNamedNodeMap 中移除节点。

public:
 virtual System::Xml::XmlNode ^ RemoveNamedItem(System::String ^ name);

public virtual System.Xml.XmlNode RemoveNamedItem (string name);

public virtual System.Xml.XmlNode? RemoveNamedItem (string name);

abstract member RemoveNamedItem : string -> System.Xml.XmlNode
override this.RemoveNamedItem : string -> System.Xml.XmlNode

Public Overridable Function RemoveNamedItem (name As String) As XmlNode

参数

name

String

要移除的节点的限定名。 该名称针对匹配节点的 Name 属性进行匹配。

返回

XmlNode

从此 XmlNode 中移除的 XmlNamedNodeMap；如果未找到匹配的节点，则为 null。

示例

以下示例使用 XmlAttributeCollection 从 XmlNamedNodeMap) 继承的类 (删除属性。

#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;
   
   // Remove the publicationdate attribute.
   attrColl->RemoveNamedItem( "publicationdate" );
   Console::WriteLine( "Display the modified XML..." );
   Console::WriteLine( doc->OuterXml );
}

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;

     // Remove the publicationdate attribute.
     attrColl.RemoveNamedItem("publicationdate");

     Console.WriteLine("Display the modified XML...");
     Console.WriteLine(doc.OuterXml);
  }
}

Imports System.IO
Imports System.Xml

public class Sample

  public shared sub Main()

    Dim doc as XmlDocument = new XmlDocument()
    doc.LoadXml("<book genre='novel' publicationdate='1997'> " & _
                "  <title>Pride And Prejudice</title>" & _
                "</book>")
                         
    Dim attrColl as XmlAttributeCollection = doc.DocumentElement.Attributes

    ' Remove the publicationdate attribute.
    attrColl.RemoveNamedItem("publicationdate")

    Console.WriteLine("Display the modified XML...")
    Console.WriteLine(doc.OuterXml)
    
  end sub
end class

RemoveNamedItem(String, String)

移除具有匹配的 LocalName 和 NamespaceURI 的节点。

public:
 virtual System::Xml::XmlNode ^ RemoveNamedItem(System::String ^ localName, System::String ^ namespaceURI);

public virtual System.Xml.XmlNode RemoveNamedItem (string localName, string namespaceURI);

public virtual System.Xml.XmlNode? RemoveNamedItem (string localName, string? namespaceURI);

abstract member RemoveNamedItem : string * string -> System.Xml.XmlNode
override this.RemoveNamedItem : string * string -> System.Xml.XmlNode

Public Overridable Function RemoveNamedItem (localName As String, namespaceURI As String) As XmlNode

参数

localName

String

要移除的节点的本地名称。

namespaceURI

String

要移除的节点的命名空间 URI。

返回

XmlNode

移除的 XmlNode；如果未找到匹配的节点，则为 null。
