XmlTextReader.XmlSpace 属性

public:
 virtual property System::Xml::XmlSpace XmlSpace { System::Xml::XmlSpace get(); };

public override System.Xml.XmlSpace XmlSpace { get; }

member this.XmlSpace : System.Xml.XmlSpace

Public Overrides ReadOnly Property XmlSpace As XmlSpace

属性值

其中一个 XmlSpace 值。 如果不存在 xml:space 作用域，则此属性默认为 XmlSpace.None.

示例

以下示例分析文件，如果 xml:space='preserve' 找到范围，则返回重要的空白。

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

public class Sample{

  public static void Main(){

     XmlTextReader reader = new XmlTextReader("authors.xml");
     reader.WhitespaceHandling = WhitespaceHandling.None;

     // Parse the file.  Return white space only if an
     // xml:space='preserve' attribute is found.
     while (reader.Read()){
       switch (reader.NodeType){
         case XmlNodeType.Element:
           Console.Write("<{0}>", reader.Name);
           if (reader.XmlSpace==XmlSpace.Preserve)
             reader.WhitespaceHandling=WhitespaceHandling.Significant;
           break;
         case XmlNodeType.Text:
           Console.Write(reader.Value);
           break;
         case XmlNodeType.EndElement:
           Console.Write("</{0}>", reader.Name);
           break;
         case XmlNodeType.SignificantWhitespace:
           Console.Write(reader.Value);
           break;
       }
     }
  }
}

Imports System.IO
Imports System.Xml

public class Sample

  public shared sub Main()

     Dim reader as XmlTextReader = new XmlTextReader("authors.xml")
     reader.WhitespaceHandling = WhitespaceHandling.None

     ' Parse the file.  Return white space only if an
     ' xml:space='preserve' attribute is found.
     while (reader.Read())
       select case reader.NodeType
         case XmlNodeType.Element:
           Console.Write("<{0}>", reader.Name)
           if (reader.XmlSpace=XmlSpace.Preserve)
             reader.WhitespaceHandling=WhitespaceHandling.Significant
           end if
         case XmlNodeType.Text:
           Console.Write(reader.Value)
         case XmlNodeType.EndElement:
           Console.Write("</{0}>", reader.Name)
         case XmlNodeType.SignificantWhitespace:
           Console.Write(reader.Value)        
       end select              
     end while
  end sub
end class

该示例使用该文件 authors.xml作为输入。
