delphi 调用 webservice (.NET C#版)

 5 XML to  XTR文件转换

 9 1、File-->open打开你要分析的XML文件
10 2、在左边选择你要分析的接点，双击加到中间的转换列表中
11 3、Create-->DataPacket from XML
12 4、Create and Test Transformation
13 5、file-->save-->Transformation得到一个.xtr的文件
14 6、打开.xtr文件，第一行找到"><SelectEach dest="DATAPACKET\ROWDATA\ROW" from="\Envelope\Body\……>
15    把‘soap：’、‘diffgr:’删除，保存
16 7、XMLTransformProvider->transformRead->TransformationFile指向.xtr文件
17 8、设置ClientDataSet1的ProviderName属性
