NAME

HTML::Object::DOM::Implementation - HTML Object DOM Implementation

SYNOPSIS

use HTML::Object::DOM::Implementation;
my $impl = HTML::Object::DOM::Implementation->new || 
    die( HTML::Object::DOM::Implementation->error, "\n" );

VERSION

v0.2.0

DESCRIPTION

The Implementation interface represents an object providing methods which are not dependent on any particular document. Such an object is returned by the "implementation" in HTML::Object::DOM::Document property.

PROPERTIES

There are no properties

METHODS

createDocument

Provided with a namespace URI (which could be an empty string) and a qualified name for the top element, which should be html and optionally a document type definition object and this creates and returns a document object.

Normally, this method is used to create an XML document, but we do not support XML, so this is basically an alias for "createHTMLDocument"

The namespaceURI argument is completely ignored, so do not bother and the qualified name can only be html.

Example:

my $doc = $doc->implementation->createDocument( $namespaceURI, $qualifiedNameStr, $documentType_object );

my $doc = $doc->implementation->createDocument( '', 'html' );
my $body = $doc->createElement( 'body' );
$body->setAttribute( 'id', 'abc' );
$doc->documentElement->appendChild( $body );
say( $doc->getElementById( 'abc') ); # [object HTMLBodyElement]

See also Mozilla documentation

createDocumentType

Provided with a qualified name, which should be html and an optional public id and system id, both of which are ignored, and this creates and returns a document type object.

Example:

my $doctype = $doc->implementation->createDocumentType( 'html', $publicId, $systemId );

my $dt = $doc->implementation->createDocumentType( 'svg:svg', '-//W3C//DTD SVG 1.1//EN', 'http://www->w3.org/Graphics/SVG/1.1/DTD/svg11.dtd' );
my $d = $doc->implementation->createDocument( 'http://www->w3.org/2000/svg', 'svg:svg', $dt );
say( $d->doctype->publicId); # -//W3C//DTD SVG 1.1//EN

See also Mozilla documentation

createHTMLDocument

Creates and returns an HTML Document.

Example:

# Assuming $title is "Demo"
my $newDoc = $doc->implementation->createHTMLDocument( $title );

Result:

<!DOCTYPE html>
<html>
    <head><title>Demo</title></head>
    <body></body>
</html>

See also Mozilla documentation

hasFeature

This always returns true.

Its original purpose is to return a boolean value indicating if a given feature is supported or not. However, this function has been unreliable and kept for compatibility purpose alone: except for SVG-related queries.

Example:

my $flag = $doc->implementation->hasFeature( $feature, $version );
