Examples of the doc option

1. In the following example, the first parameter of %XML and %DATA is the name of a file. Option doc=file must be specified.

      ifsfile1 = 'myfile.xml';
      ifsfile2 = 'myfile.json';
      ifsfile3 = 'myfile.csv';
   
      opt = 'doc=file';
      XML-INTO myfield %XML(ifsfile1 : opt);
      DATA-INTO myfield %DATA(ifsfile2 : opt) %PARSER('MYJSONPARS');
      DATA-GEN myfield %DATA(ifsfile3 : opt) %GEN('MYCSVGEN');

2. In the following example, the first parameter of %XML and %DATA is a character variable containing an document for the XML-INTO or DATA-INTO operations, and a character variable to receive the document for the DATA-GEN operation. Since the doc option defaults to “string”, no options are necessary. However, option doc=string may be specified. In the following example, each pair of operations is equivalent.

      xmldata = '<data><num>3</num></data>';
      XML-INTO data %XML(xmldata);
      XML-INTO data %XML(xmldata : 'doc=string');
   
      jsondata = '{"data":{"num":"3"}}';
      DATA-INTO data %DATA(jsondata) %PARSER('MYJSONPARS');
      DATA-INTO data %DATA(jsondata : 'doc=string') %PARSER('MYJSONPARS');
   
      chain (id) custRec rec custDs;
      DATA-GEN custDs %DATA(custInfo) %GEN('MYCSVGEN');
      DATA-GEN custDs %DATA(custInfo : 'doc=string') %GEN('MYCSVGEN');
