Web Service is the fitted technical solution which provides the required loose coupling to achieve Service Oriented Architecture (SOA). In previous works, we propose an approach, using the Aspect Oriented Programming (AOP) paradigm, to increase the adaptability of Web Services. This approach suffers from some deficiencies as dependency for both the programming language (Java) and the SOAP engine (AXIS). In this paper, we propose to increase the adaptability of Web Services by using the main AOP agreed semantics - advices, pointcuts and joinpoint- to change original Web Service behavior. In the new approach we consider that advices are themselves a web service. Moreover, we propose to use an XML Language for describe pointcuts, joinpoint and to referencing advices. The invocation of advices (Web Services) is accomplished by an XQuery engine to assure SOAP Engine independency and Advices are implemented as Web Services to promote programming language independency.
