XDocumentType Constructor (String, String, String, String)

 

Initializes an instance of the XDocumentType class.

Namespace:   System.Xml.Linq
Assembly:  System.Xml.Linq (in System.Xml.Linq.dll)

Public Sub New (
	name As String,
	publicId As String,
	systemId As String,
	internalSubset As String
)

Parameters

name
Type: System.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
Type: System.String

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

systemId
Type: System.String

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

internalSubset
Type: System.String

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

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.


                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>
