This method creates a DOM document. | DOMImplementation | ||

| DOM 2 Core createDocument | () | method |
public function createDocument(namespaceURI:DOMString, qualifiedName:DOMString, doctype:DocumentType):Document| Introduced in: | DOM 2 Core |
This method creates a DOM document.
Parameters
namespaceURI:DOMString — The namespace URI of the document element to
create or null.
| |
qualifiedName:DOMString — The qualified name of the document element to
be created or null.
| |
doctype:DocumentType — The type of document to be created or null.
When doctype is not null, its Node.ownerDocument attribute is set to
the document being created.
|
Document — A new Document object with its document element. If the NamespaceURI,
qualifiedName, and doctype are null, the returned Document is 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].
| |
DOMException — NAMESPACE_ERR: Raised if the
qualifiedName is malformed, if the qualifiedName has a prefix and the
namespaceURI is null, or if the qualifiedName is null and the
namespaceURI is different from null, or if the qualifiedName has a
prefix that is "xml" and the namespaceURI is 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.
| |
DOMException — WRONG_DOCUMENT_ERR: Raised if doctype has
already been used with a different document or was created from a
different implementation.
| |
DOMException — 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.

public function createDocumentType(qualifiedName:DOMString, publicId:DOMString, systemId:DOMString):DocumentType| Introduced in: | DOM 2 Core |
Creates an empty DocumentType node.
Entity declarations and notations are not made available. Entity reference expansions and default attribute additions do not occur.
Parameters
qualifiedName:DOMString — The qualified name of the document type to be created.
| |
publicId:DOMString — The external subset public identifier.
| |
systemId:DOMString — The external subset system identifier.
|
DocumentType — A new DocumentType node with Node.ownerDocument set to null.
|
DOMException — INVALID_CHARACTER_ERR: Raised if the
specified qualified name is not an XML name according to [XML 1.0].
| |
DOMException — NAMESPACE_ERR: Raised if the
qualifiedName is malformed.
| |
DOMException — 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.

public function getFeature(feature:DOMString, version:DOMString):DOMObject| Introduced in: | DOM 3 Core |
This method returns a specialized object which implements the specialized APIs of the specified feature and version, as specified in DOM Features.
The specialized object may also be obtained by using binding-specific casting methods but is not necessarily expected to, as discussed in Mixed DOM Implementations. This method also allow the implementation to provide specialized objects which do not support the DOMImplementation interface.
Parameters
feature:DOMString — 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:DOMString — This is the version number of the feature to test.
|
DOMObject — Returns an object which implements the specialized APIs of the
specified feature and version, if any, or null if there is no object
which implements interfaces associated with that feature. If the DOMObject
returned by this method implements the DOMImplementation interface, it
must delegate to the primary core DOMImplementation and not return results
inconsistent with the primary core DOMImplementation such as hasFeature,
getFeature, etc.

}| DOM 1 Core hasFeature | () | method |
public function hasFeature(feature:DOMString, version:DOMString):Boolean| Introduced in: | DOM 1 Core |
Test if the DOM implementation implements a specific feature and version, as specified in DOM Features.
Parameters
feature:DOMString — The name of the feature to test.
| |
version:DOMString — This is the version number of the feature to test.
|
Boolean — If the feature is implemented in the specified version.
