Web Services, Part XI: Consuming Multiple Web Services

In this column we continue our series on Web services. In Part I, we introduced you to this hot topic. In Part II, we showed you how to call Web services. In Part III, we presented the WebService behavior and its four supported methods. In Part IV, we continued our coverage of the WebService behavior by describing its objects and properties. In Part V, we dove into XML and XSLT. In Part VI, we started a miniseries on how to load and manipulate XML files from JavaScript.
