How can perform a bulk record deletion in a zoho creator app?

How can perform a bulk record deletion in a zoho creator app?

Hello, 
I am Developing a solution and i am trying to create a function that will delete all records in all forms in the application.
here is what i've been able to come up with:

  2. string AppConfig.clearAllAppData()
  3. {
  4. /**********************************Log variable declaration**************************************/
  5. fullLog = "";
  6. name = "";
  7. recCounts = "";
  8. deleted = false ;
  9. /**********************************END-Log variable declaration**************************************/
  11. /*************************CONST VARIABLES*********************************/
  12. format = "xml";
  13. applicationName = zoho.appname;
  14. appuri = zoho.appuri;
  15. authToken = "3bd****************************8b";
  16. /*************************END-CONST VARIABLES*********************************/
  18. /*************************OBJECT TO BE PASSED HTML GET FUNCTION*****************************/
  19. endPoint = "https://creator.zoho.com/api/"+format+"/"+applicationName+"/forms";
  20. params = Map();
  21. params.put("authtoken", authToken);
  22. params.put("scope", "creatorapi");
  23. params.put("zc_ownername", zoho.adminuser);
  24. /*************************END-OBJECT TO BE PASSED HTML GET FUNCTION*****************************/
  25. appForms = invokeUrl
  26. [
  27. url : endPoint
  28. type : GET
  29. parameters : params
  30. ];
  31. formsCount = appForms.executeXPath("response/application[@name='chservicesalesmgt1-ide']/formlist/formcount/text()");
  32. formLinkNames = appForms.executeXPath("response/application[@name='chservicesalesmgt1-ide']/formlist/form/componentname/text()");
  33. formLinkNamesList = formLinkNames.toList("-|-");
  35. for each _form in formLinkNamesList
  36.     {
  37. delete from _form [ ID != null ];
  38. // if ( _form[ID != null].count() == 0 ) 
  39. //         {
  40. // fullLog = fullLog + ", "+form ;
  41. // delete from _form [ ID != null ];
  42. //         }
  43.     }

  46. return "Application data has been deleted successfully";
  47. }

however, it seem i cannot reference form link name through the variable "_form" that holds the form_link_name.

here is the error i get when i try to save it:
