XDocumentType.NodeType 属性

定义

命名空间:

System.Xml.Linq

程序集:

System.Xml.XDocument.dll

程序集:

System.Xml.Linq.dll

程序集:

netstandard.dll

获取此节点的节点类型。

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

public override System.Xml.XmlNodeType NodeType { get; }

member this.NodeType : System.Xml.XmlNodeType

Public Overrides ReadOnly Property NodeType As XmlNodeType

属性值

XmlNodeType

节点类型。 对于 XDocumentType 对象，此值为 DocumentType。

示例

下面的示例演示如何使用此属性检索对象的 XDocumentType 节点类型。

string internalSubset = @"<!ELEMENT Pubs (Book+)>  
<!ELEMENT Book (Title, Author)>  
<!ELEMENT Title (#PCDATA)>  
<!ELEMENT Author (#PCDATA)>";  

string target = "xml-stylesheet";  
string data = "href=\"mystyle.css\" title=\"Compact\" type=\"text/css\"";  

XDocument doc = new XDocument(  
    new XComment("This is a comment."),  
    new XProcessingInstruction(target, data),  
    new XDocumentType("Pubs", null, null, internalSubset),  
    new XElement("Pubs",   
        new XElement("Book",  
            new XElement("Title", "Artifacts of Roman Civilization"),  
            new XElement("Author", "Moreno, Jordao")  
        ),  
        new XElement("Book",  
            new XElement("Title", "Midieval Tools and Implements"),  
            new XElement("Author", "Gazit, Inbar")  
        )  
    ),  
    new XComment("This is another comment.")  
);  
doc.Declaration = new XDeclaration("1.0", "utf-8", "true");  

Console.WriteLine(doc.DocumentType.NodeType);  

Dim internalSubset = _  
    "<!ELEMENT Pubs (Book+)>" & Environment.NewLine & _  
    "<!ELEMENT Book (Title, Author)>" & Environment.NewLine & _  
    "<!ELEMENT Title (#PCDATA)>" & Environment.NewLine & _  
    "<!ELEMENT Author (#PCDATA)>"  

Dim doc As XDocument = _   
    <?xml version="1.0" encoding="utf-8" standalone="yes"?>  
    <!--This is a comment.-->  
    <?xml-stylesheet href='mystyle.css' title='Compact' type='text/css'?>  
    <Pubs>  
        <Book>  
            <Title>Artifacts of Roman Civilization</Title>  
            <Author>Moreno, Jordao</Author>  
        </Book>  
        <Book>  
            <Title>Midieval Tools and Implements</Title>  
            <Author>Gazit, Inbar</Author>  
        </Book>  
    </Pubs>  
    <!--This is another comment.-->  

doc.FirstNode.AddAfterSelf(new XDocumentType("Pubs", Nothing, Nothing, internalSubset))  

Console.WriteLine(doc.DocumentType.NodeType.ToString())  

该示例产生下面的输出：

DocumentType  

注解

由于派生自 XObject 包含属性 NodeType 的所有类，因此可以编写对具体子类 XObject集合进行操作的代码。 然后，代码可以测试集合中每个节点的节点类型。
