public interface DOMImplementation
DOMImplementation
interface provides a number of methods
for performing operations that are independent of any particular instance
of the document object model.
See also the Document Object Model (DOM) Level 2 Core Specification.
Method Summary | |
---|---|
Document | createDocument(String namespaceURI, String qualifiedName, DocumentType doctype)
Creates a DOM Document object of the specified type with its document
element. |
DocumentType | createDocumentType(String qualifiedName, String publicId, String systemId)
Creates an empty DocumentType node. |
boolean | hasFeature(String feature, String version)
Test if the DOM implementation implements a specific feature. |
Parameters: namespaceURI The namespace URI of the document element to
create. qualifiedName The qualified name of the document element to be
created. doctype 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.
Returns: A new Document
object.
Throws: DOMException
INVALID_CHARACTER_ERR: Raised if the specified qualified name
contains an illegal character.
NAMESPACE_ERR: Raised if the qualifiedName
is
malformed, if the qualifiedName
has a prefix and the
namespaceURI
is null
, or if the
qualifiedName
has a prefix that is "xml" and the
namespaceURI
is different from "
http://www.w3.org/XML/1998/namespace" , 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 doctype
has already
been used with a different document or was created from a different
implementation.
NOT_SUPPORTED_ERR: May be raised by DOM implementations which do
not support the "XML" feature, if they choose not to support this
method. Other features introduced in the future, by the DOM WG or
in extensions defined by other groups, may also demand support for
this method; please consult the definition of the feature to see if
it requires this method.
Since: DOM Level 2
DocumentType
node. Entity declarations
and notations are not made available. Entity reference expansions and
default attribute additions do not occur. It is expected that a
future version of the DOM will provide a way for populating a
DocumentType
.Parameters: qualifiedName The qualified name of the document type to be created. publicId The external subset public identifier. systemId The external subset system identifier.
Returns: A new DocumentType
node with
Node.ownerDocument
set to null
.
Throws: DOMException
INVALID_CHARACTER_ERR: Raised if the specified qualified name
contains an illegal character.
NAMESPACE_ERR: Raised if the qualifiedName
is
malformed.
NOT_SUPPORTED_ERR: May be raised by DOM implementations which do
not support the "XML"
feature, if they choose not to
support this method. Other features introduced in the future, by
the DOM WG or in extensions defined by other groups, may also
demand support for this method; please consult the definition of
the feature to see if it requires this method.
Since: DOM Level 2
Parameters: feature The name of the feature to test (case-insensitive). The
values used by DOM features are defined throughout the DOM Level 2
specifications and listed in the section. The name must be an XML
name. To avoid possible conflicts, as a convention, names referring
to features defined outside the DOM specification should be made
unique. version This is the version number of the feature to test. In
Level 2, the string can be either "2.0" or "1.0". If the version is
not specified, supporting any version of the feature causes the
method to return true
.
Returns: true
if the feature is implemented in the
specified version, false
otherwise.
