摘　　要：国外有人设计了一种新的实现 Web Services的 XML编程语言—— XL。 XL完全适应 W3C的标准。其主要优点是让编程人员集中关注程序的应用逻辑。XL 为 Actions提供了在 Web Services实现中执行的典型高层级开放结构 ,编程人员的效率、程序的进化能力等将有实质性的提高。本文介绍了 XL 的语法 ,并给出一个 XL Web Service程序实例。XL- an XML programming language has been designed abroad for the implementation of Web Services. XL is fully compliant with W3C standards. One of the key features of XL is that it allows programmers to concentrate on the logic of their application. XL provides high level and declarative constructs for actions typically carried out in the implementation of a Web Service, the productivity of the programmers, the ability of evolution of the programs, and the chances to achieve good performance are substantially enhanced. This paper mainly introduces syntax of XL and gives an example of a Web Service written in XL.
