XmlNodeReader.Skip 方法

定义

跳过当前节点的子级。

public:
 override void Skip();
public override void Skip ();
override this.Skip : unit -> unit
Public Overrides Sub Skip ()

示例

以下示例读取 XML 文档中的价格元素节点。

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
{
   XmlNodeReader^ reader = nullptr;
   try
   {
      
      //Create and load the XML document.
      XmlDocument^ doc = gcnew XmlDocument;
      doc->LoadXml( "<!-- sample XML -->"
      "<book>"
      "<title>Pride And Prejudice</title>"
      "<price>19.95</price>"
      "</book>" );
      
      //Load the XmlNodeReader 
      reader = gcnew XmlNodeReader( doc );
      reader->MoveToContent(); //Move to the book node.
      reader->Read(); //Read the book start tag.
      reader->Skip(); //Skip the title element.
      Console::WriteLine( reader->ReadOuterXml() ); //Read the price element.
   }
   finally
   {
      if ( reader != nullptr )
            reader->Close();
   }

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

public class Sample
{
  public static void Main()
  {
    XmlNodeReader reader = null;

    try
    {
       //Create and load the XML document.
       XmlDocument doc = new XmlDocument();
       doc.LoadXml("<!-- sample XML -->" +
                   "<book>" +
                   "<title>Pride And Prejudice</title>" +
                   "<price>19.95</price>" +
                   "</book>");

       //Load the XmlNodeReader
       reader = new XmlNodeReader(doc);

       reader.MoveToContent(); //Move to the book node.
       reader.Read();  //Read the book start tag.
       reader.Skip();   //Skip the title element.

       Console.WriteLine(reader.ReadOuterXml());  //Read the price element.
     }

注解

备注

在 .NET Framework 2.0 中,建议的做法是使用XmlReaderSettings类和Create方法创建XmlReader实例。 这使你可以充分利用.NET Framework中引入的所有新功能。 有关详细信息,请参阅参考页中的 XmlReader “备注”部分。

例如,假设具有以下 XML 输入:

<a name="bob" age="123">  
   <x/>abc<y/>  
 </a>  
 <b>  
...  
 </b>  

如果读取器位于“<a>”节点或其任何属性上,则调用 Skip 读取器定位到“<b>”节点。

如果读取器位于叶节点上已 ((如元素“x”或文本节点“abc”) ),则调用 Skip 与调用 Read相同。

此方法检查格式正确的 XML。
