    Propriedades

    name

    O nome do atributo

    ownerElement

    O elemento que contém o atributo ou null.

    schemaTypeInfo

    Não foi implementado ainda, sempre será null

    specified

    Não foi implementado ainda, sempre será true

    value

    O valor do atributo.

    Nota:

    Observe que entidades XML são expandidas ao atribuir um valor. Portanto o caracter & tem um comportamento especial. Configurar um value para si mesmo irá falhar se value contiver um &. Para evitar uma substituição de entidades, utilize DOMElement::setAttribute().

    Please take care on debugging DOMAttr related code. This will cause an E_WARNING that retrieving schemaTypeInfo attribute is not implemented yet. An IDE like Eclipse will inspect the object and its member elements. In conjunction with registered error handlers, which will translate the E_WARNING into Exception your debugging session will end unexpectedly. This has caused me some trouble while debugging my PHPUnit test case in eclipse using "Makegood" plugin.

    A possible workarround is to deactivate the error handling during debugging using error_reporting(0). Remove the statement after finishing your debugging session.

    See also the properties from the inherited class DOMNode ( http://php.net/manual/en/class.domnode.php ), eg. namespaceURI, prefix, localName, etc, especially if you have to deal with namespaced attributes
