XmlDocumentType::IsReadOnly Property
.NET Framework (current version)
Gets a value indicating whether the node is read-only.
Assembly: System.Xml (in System.Xml.dll)
Property Value
Type: System::Booleantrue if the node is read-only; otherwise false.
Because DocumentType nodes are read-only, this property always returns true.
A read-only node is one whose properties, attributes, or children cannot be changed. However, you can remove a read-only node from the tree and insert it somewhere else.
You can remove a XmlDocumentType from a document and reinsert it back into the document as long as the document does not have an element node. Once a document has a root element, its XmlDocumentType cannot be changed.
This property is a Microsoft extension to the Document Object Model (DOM).
The following example displays information about the DocumentType node.
#using <System.Xml.dll> using namespace System; using namespace System::IO; using namespace System::Xml; int main() { // Create the XmlDocument. XmlDocument^ doc = gcnew XmlDocument; doc->LoadXml( "<!DOCTYPE book [<!ENTITY h 'hardcover'>]>" "<book genre='novel' ISBN='1-861001-57-5'>" "<title>Pride And Prejudice</title>" "<style>&h;</style>" "</book>" ); // Check if the node is read-only. if ( doc->DocumentType->IsReadOnly ) Console::WriteLine( "Document type nodes are always read-only" ); }
