org.w3c.dom.DOMImplementation |
The 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.
Public Methods | |||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|
Creates an XML
Document object of the specified type with
its document element. | |||||||||||
Creates an empty
DocumentType node. | |||||||||||
Test if the DOM implementation implements a specific feature.
|
Creates an XML Document
object of the specified type with
its document element. HTML-only DOM implementations do not need to
implement this method.
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. |
Document
object.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" .
WRONG_DOCUMENT_ERR: Raised if doctype has already
been used with a different document or was created from a different
implementation. |
---|
Creates an empty 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
.
HTML-only DOM implementations do not need to implement this method.
qualifiedName | The qualified name of the document type to be created. |
---|---|
publicId | The external subset public identifier. |
systemId | The external subset system identifier. |
DocumentType
node with
Node.ownerDocument
set to null
.DOMException | INVALID_CHARACTER_ERR: Raised if the specified qualified name
contains an illegal character.
NAMESPACE_ERR: Raised if the qualifiedName is
malformed. |
---|
Test if the DOM implementation implements a specific feature.
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 by reversing the name of the Internet domain name of the person (or the organization that the person belongs to) who defines the feature, component by component, and using this as a prefix. For instance, the W3C SVG Working Group defines the feature "org.w3c.dom.svg". |
---|---|
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 . |
true
if the feature is implemented in the
specified version, false
otherwise.
