when i try to parse the string

with this code

             counter=0;
                while (parser.nextToken() != null && counter<10)
                {
                counter++;
                    if ((parser.getCurrentToken() == JSONToken.FIELD_NAME) && (parser.getText() == 'total_records'))
                     {
                     
                            // Get the value.
                                parser.nextToken();
                            // Compute the grand total price for all invoices.
                            Temp=parser.getText();
                            file_count=integer.valueof(Temp);
                            if(file_count==0)
                            {
                             file_exists=0;
                            
                             }
                           // csv_ids.add( Temp);
                      }
                }
                counter=0;
                 
my json string is

{"success":true,"total_records":1,"data":[{"file_name":"aaavalid.csv"}]}

Unexpected character ('<' (code 60)): expected a valid value (number, String, array, object, 'true', 'false' or 'null') at input location [1,4]
