XML::DOM::Document(3) User Contributed Perl DocumentationXML::DOM::Document(3)NAMEXML::DOM::Document - An XML document node in XML::DOM
DESCRIPTIONXML::DOM::Document extends XML::DOM::Node.
It is the main root of the XML document structure as returned by
XML::DOM::Parser::parse and XML::DOM::Parser::parsefile.
Since elements, text nodes, comments, processing instructions, etc.
cannot exist outside the context of a Document, the Document interface
also contains the factory methods needed to create these objects. The
Node objects created have a getOwnerDocument method which associates
them with the Document within whose context they were created.
METHODS
getDocumentElement
This is a convenience method that allows direct access to the child
node that is the root Element of the document.
getDoctype
The Document Type Declaration (see DocumentType) associated with
this document. For HTML documents as well as XML documents without
a document type declaration this returns undef. The DOM Level 1
does not support editing the Document Type Declaration.
Not In DOM Spec: This implementation allows editing the doctype.
See XML::DOM::ignoreReadOnly for details.
getImplementation
The DOMImplementation object that handles this document. A DOM
application may use objects from multiple implementations.
createElement (tagName)
Creates an element of the type specified. Note that the instance
returned implements the Element interface, so attributes can be
specified directly on the returned object.
DOMExceptions:
* INVALID_CHARACTER_ERR
Raised if the tagName does not conform to the XML spec.
createTextNode (data)
Creates a Text node given the specified string.
createComment (data)
Creates a Comment node given the specified string.
createCDATASection (data)
Creates a CDATASection node given the specified string.
createAttribute (name [, value [, specified ]])
Creates an Attr of the given name. Note that the Attr instance can
then be set on an Element using the setAttribute method.
Not In DOM Spec: The DOM Spec does not allow passing the value or
the specified property in this method. In this implementation they
are optional.
Parameters:
value The attribute's value. See Attr::setValue for details.
If the value is not supplied, the specified property
is set to 0.
specified Whether the attribute value was specified or whether the
default
value was used. If not supplied, it's assumed to be
1.
DOMExceptions:
* INVALID_CHARACTER_ERR
Raised if the name does not conform to the XML spec.
createProcessingInstruction (target, data)
Creates a ProcessingInstruction node given the specified name and
data strings.
Parameters:
target The target part of the processing instruction.
data The data for the node.
DOMExceptions:
* INVALID_CHARACTER_ERR
Raised if the target does not conform to the XML spec.
createDocumentFragment
Creates an empty DocumentFragment object.
createEntityReference (name)
Creates an EntityReference object.
Additional methods not in the DOM Spec
getXMLDecl and setXMLDecl (xmlDecl)
Returns the XMLDecl for this Document or undef if none was speci-
fied. Note that XMLDecl is not part of the list of child nodes.
setDoctype (doctype)
Sets or replaces the DocumentType. NOTE: Don't use appendChild or
insertBefore to set the DocumentType. Even though doctype will be
part of the list of child nodes, it is handled specially.
getDefaultAttrValue (elem, attr)
Returns the default attribute value as a string or undef, if none
is available.
Parameters:
elem The element tagName.
attr The attribute name.
getEntity (name)
Returns the Entity with the specified name.
createXMLDecl (version, encoding, standalone)
Creates an XMLDecl object. All parameters may be undefined.
createDocumentType (name, sysId, pubId)
Creates a DocumentType object. SysId and pubId may be undefined.
createNotation (name, base, sysId, pubId)
Creates a new Notation object. Consider using XML::DOM::Document-
Type::addNotation!
createEntity (parameter, notationName, value, sysId, pubId, ndata)
Creates an Entity object. Consider using XML::DOM::Document-
Type::addEntity!
createElementDecl (name, model)
Creates an ElementDecl object.
DOMExceptions:
* INVALID_CHARACTER_ERR
Raised if the element name (tagName) does not conform to the
XML spec.
createAttlistDecl (name)
Creates an AttlistDecl object.
DOMExceptions:
* INVALID_CHARACTER_ERR
Raised if the element name (tagName) does not conform to the
XML spec.
expandEntity (entity [, parameter])
Expands the specified entity or parameter entity (if parameter=1)
and returns its value as a string, or undef if the entity does not
exist. (The entity name should not contain the '%', '&' or ';'
delimiters.)
check ( [$checker] )
Uses the specified XML::Checker to validate the document. If no
XML::Checker is supplied, a new XML::Checker is created. See
XML::Checker for details.
check_sax ( [$checker] )
Similar to check() except it uses the SAX interface to XML::Checker
instead of the expat interface. This method may disappear or
replace check() at some time.
createChecker ()
Creates an XML::Checker based on the document's DTD. The $checker
can be reused to check any elements within the document. Create a
new XML::Checker whenever the DOCTYPE section of the document is
altered!
