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);

参数
示例
以下示例使用内部 DTD 创建文档。 创建 XDocumentType 对象时,它指定 DTD(Pubs)的限定名称,以及包含内部子集的字符串。 由于文档不使用公共或专用外部 DTD,因此
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)
此示例生成以下输出:
<!--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>
