App Engine running XML Publisher with PS Query Data Source

Haven't you notice that every posts up to this point are XML Publisher related? I just can get enough of this tools, i like discovering what this tool can do for me as a developer. If using Rowset Data Source in XMLP was too complicated for you, try using the PS Query as the Data Source. You don't need to create a code for sample data file and schema file because you can generate those files within PeopleSoft. Just replace the Rowset code in the XML Publisher Part 2 with this code;

/*fill prompt record*/
&rcdQryPrompts = &ReportDef.GetPSQueryPromptRecord();
If Not &rcdQryPrompts = Null Then
If Not Prompt(&ReportDef.GetDataSource().Name, "",&rcdQryPrompts) Then
Exit;
End-If;
&ReportDef.ProcessReport(&sTemplateId, %Language_User, %Date, &sOutputFormat);
End-If;
