使用AE调用XML Publisher 时。数据源的选择和生成报表的代码紧密相关。

XML File 数据源： 所用方法 SetRuntimedataxMLFile

XML Doc 数据源： 所用方法 SetRuntimedataxMLDoc

RowSet 数据源： 使用方法 SetRuntimeDataRowset

Query数据源 ： SetPSQueryPromptRecord

数据源和生成方法必须一一对应。

此由如下代码控制：

Evaluate &Report.Ds_type
   When = "QRY"
      rem rsh ICE 1836783000;
      &sDataFile = %This.sSrvTmpDir | &sDirSep | "Data" | &sDirSep | &sDataFile;
      %This.GenerateXmlFileFromQuery(&sDataFile);
      Break;
   When = "CQR" /* Connected Query */
      rem mdu XXX %This.GenerateXmlFileFromConnQuery(&sConQryOutFileName,&sProcessId);
      %This.GenerateXmlFileFromConnQuery(&sConQryOutFileName,String(&ProcessInstance)); /* mdu XXX */
      If Not FileExists(&sConQryOutFileName,%FilePath_Absolute) Then
         throw CreateException(235,2308,"Data file is required but not specified correctly");
      Else
         %This.SetRuntimedataxMLFile(&sConQryOutFileName);
      End-If;
      &sDataFile = &dataxMLFile;
      Break;
   When = "RST"
      rem rshw TODO: This function needs to be passed file path instead of returning string;
      &sXmlData = %This.GenerateXmlFromRowset();
      If &sXmlData = "" Then
         throw CreateException(235,2305,"Failed to generate or read data source XML file");
      End-If;
      rem rsh ICE 1836783000;
      &sDataFile = %This.sSrvTmpDir | &sDirSep | "Data" | &sDirSep | &sDataFile;
      %This.WriteXmlDataFile(&sXmlData,&sDataFile);
      Break;
   When = "XMD"
      &sXmlData = %This.GenerateXmlFromXmlDoc();
      If &sXmlData = "" Then
         throw CreateException(235,&sDataFile);
      Break;
   When = "XML"
      If &dataxMLFile = "" Then
         throw CreateException(235,"Data file is required but not specified correctly");
      End-If;
      &sDataFile = &dataxMLFile;
      Break;
