    Propiedades

    name

    El nombre del atributo.

    ownerElement

    El elemento que contiene el atributo o null.

    schemaTypeInfo

    Aún no implementado, siempre vale null.

    specified

    Aún no implementado, siempre vale null.

    value

    El valor del atributo.

    Nota:

    Tenga en cuenta que las entidades XML se expanden cuando se define un valor. Por lo tanto, el carácter & tiene un significado especial. Establecer valor a sí mismo fallará cuando valor contiene un &. Para evitar la expansión de entidades, utilice en su lugar 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
