Thus, all the references in your Vector point to the same object. This is specifically allowed by the SAX spec. The documentation for AttributeList states, "The instance provided will return valid results only during the scope of the startElement invocation (to save it for future use, the application must make a copy: the AttributeListImpl helper class provides a convenient constructor for doing so)." -- Ron Bourret xml-dev: A list for W3C XML Developers.
