createDocument
public Document createDocument(String namespaceURI,
                               String qualifiedName,
                               DocumentType doctype)
            throws DOMException Creates a DOM Document object of the specified type with its document 
 element.
 
Note that based on the 
DocumentType given to create 
 the document, the implementation may instantiate specialized 
 
Document objects that support additional features than 
 the "Core", such as "HTML" [
DOM Level 2 HTML]
 . On the other hand, setting the 
DocumentType after the 
 document was created makes this very unlikely to happen. 
 Alternatively, specialized 
Document creation methods, 
 such as 
createHTMLDocument [
DOM Level 2 HTML]
 , can be used to obtain specific types of 
Document 
 objects.
- namespaceURI- The namespace URI of the document element to 
create or- null.
- qualifiedName- The qualified name of the document element to be 
created or- null.
- doctype- The type of document to be created or- null.
When- doctypeis not- null, its- Node.ownerDocumentattribute is set to the document 
being created.
- A new Documentobject with its document element. 
If theNamespaceURI,qualifiedName, anddoctypearenull, the returnedDocumentis empty with no document element.
- DOMException- INVALID_CHARACTER_ERR: Raised if the specified qualified name is not 
an XML name according to [XML 1.0].
 NAMESPACE_ERR: Raised if the- qualifiedNameis 
malformed, if the- qualifiedNamehas a prefix and the- namespaceURIis- null, or if the- qualifiedNameis- nulland the- namespaceURIis different from- null, or 
if the- qualifiedNamehas a prefix that is "xml" and 
the- namespaceURIis different from "
http://www.w3.org/XML/1998/namespace" [XML Namespaces]
, or if the DOM implementation does not support the- "XML"feature but a non-null namespace URI was 
provided, since namespaces were defined by XML.
 WRONG_DOCUMENT_ERR: Raised if- doctypehas already 
been used with a different document or was created from a different 
implementation.
 NOT_SUPPORTED_ERR: May be raised if the implementation does not 
support the feature "XML" and the language exposed through the 
Document does not support XML Namespaces (such as [HTML 4.01]).
- DOM Level 2
createDocumentType
public DocumentType createDocumentType(String qualifiedName,
                                       String publicId,
                                       String systemId)
            throws DOMException Creates an empty DocumentType node. Entity declarations 
 and notations are not made available. Entity reference expansions and 
 default attribute additions do not occur..
- qualifiedName- The qualified name of the document type to be 
created.
- publicId- The external subset public identifier.
- systemId- The external subset system identifier.
- A new DocumentTypenode withNode.ownerDocumentset tonull.
- DOMException- INVALID_CHARACTER_ERR: Raised if the specified qualified name is not 
an XML name according to [XML 1.0].
 NAMESPACE_ERR: Raised if the- qualifiedNameis 
malformed.
 NOT_SUPPORTED_ERR: May be raised if the implementation does not 
support the feature "XML" and the language exposed through the 
Document does not support XML Namespaces (such as [HTML 4.01]).
- DOM Level 2
getFeature
public Object getFeature(String feature,
                         String version)  This method returns a specialized object which implements the 
 specialized APIs of the specified feature and version, as specified 
 in . The specialized object may also be obtained by using 
 binding-specific casting methods but is not necessarily expected to, 
 as discussed in . This method also allow the implementation to 
 provide specialized objects which do not support the 
 DOMImplementation interface. 
- feature- The name of the feature requested. Note that any plus 
sign "+" prepended to the name of the feature will be ignored since 
it is not significant in the context of this method.
- version- This is the version number of the feature to test.
- Returns an object which implements the specialized APIs of 
the specified feature and version, if any, or nullif 
there is no object which implements interfaces associated with that 
feature. If theDOMObjectreturned by this method 
implements theDOMImplementationinterface, it must 
delegate to the primary coreDOMImplementationand not 
return results inconsistent with the primary coreDOMImplementationsuch ashasFeature,getFeature, etc.
- DOM Level 3
hasFeature
public boolean hasFeature(String feature,
                          String version) Test if the DOM implementation implements a specific feature and 
 version, as specified in .
- feature- The name of the feature to test.
- version- This is the version number of the feature to test.
- trueif the feature is implemented in the 
specified version,- falseotherwise.
