HTML::DOM::Attr(3) User Contributed Perl Documentation HTML::DOM::Attr(3) NAME HTML::DOM::Attr - A Perl class for representing attribute nodes in an HTML DOM tree VERSION Version 0.058 SYNOPSIS use HTML::DOM; $doc = HTML::DOM->new; $attr = $doc->createAttribute('href'); $attr->nodeValue('http://localhost/'); $elem = $doc->createElement('a'); $elem->setAttributeNode($attr); $attr->nodeName; # href $attr->nodeValue; # http://... $attr->firstChild; # a text node $attr->ownerElement; # returns $elem DESCRIPTION This class is used for attribute nodes in an HTML::DOM tree. It implements the Node and Attr DOM interfaces and inherits from HTML::DOM::EventTarget. An attribute node stringifies to its value. As a boolean it is true, even if its value is false. METHODS Attributes The following DOM attributes are supported: nodeName name These both return the name of the attribute. nodeType Returns the constant "HTML::DOM::Node::ATTRIBUTE_NODE". nodeValue value These both return the attribute's value, setting it if there is an argument. specified Returns true if the attribute was specified explicitly in the source code or was explicitly added to the tree. parentNode previousSibling nextSibling attributes namespaceURI prefix localName All of these simply return an empty list. childNodes In scalar context, this returns a node list object with one text node in it. In list context it returns a list containing just that text node. firstChild lastChild These both return the attribute's text node. ownerDocument Returns the document to which the attribute node belongs. ownerElement Returns the element to which the attribute belongs. Other Methods insertBefore removeChild appendChild These three just throw exceptions. replaceChild If the first argument is a text node and the second is the attribute node's own text node, then the latter is replaced with the former. This throws an exception otherwise. hasChildNodes Returns true. cloneNode Returns a clone of the attribute. normalize Does nothing. hasAttributes Returns false. isSupported Does the same thing as HTML::DOM::Implementation's hasFeature method.
