XDocumentType(String, String, String, String)

Source:
XDocumentType.cs
Source:
XDocumentType.cs
Source:
XDocumentType.cs

Initializes an instance of the XDocumentType class.

public:
 XDocumentType(System::String ^ name, System::String ^ publicId, System::String ^ systemId, System::String ^ internalSubset);
public XDocumentType (string name, string publicId, string systemId, string internalSubset);
public XDocumentType (string name, string? publicId, string? systemId, string internalSubset);
public XDocumentType (string name, string? publicId, string? systemId, string? internalSubset);
new System.Xml.Linq.XDocumentType : string * string * string * string -> System.Xml.Linq.XDocumentType
Public Sub New (name As String, publicId As String, systemId As String, internalSubset As String)

Parameters

name
String

A String that contains the qualified name of the DTD, which is the same as the qualified name of the root element of the XML document.

publicId
String

A String that contains the public identifier of an external public DTD.

systemId
String

A String that contains the system identifier of an external private DTD.

internalSubset
String

A String that contains the internal subset for an internal DTD.

Examples

The following example creates a document with an internal DTD. When it creates the XDocumentType object, it specifies the qualified name of the DTD (Pubs), and a string that contains the internal subset. Because the document does not use a public or private external DTD, the publicId and systemId are set to null.

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);  

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.NextNode.AddAfterSelf(new XDocumentType("Pubs", Nothing, Nothing, internalSubset))  

Console.WriteLine(doc)

This example produces the following output:

<!--This is a comment.-->  
<?xml-stylesheet href="mystyle.css" title="Compact" type="text/css"?>  
<!DOCTYPE Pubs [<!ELEMENT Pubs (Book+)>  
<!ELEMENT Book (Title, Author)>  
<!ELEMENT Title (#PCDATA)>  
<!ELEMENT Author (#PCDATA)>]>  
<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.-->
