Example of AdditionalInputPort

Example of AdditionalInputPort

Suppose you have two text files:
  • IdsAndSalaries.txt
     is a table of employee IDs and salaries.
  • IdsAndNames.txt
     is a table of employee IDs and names.
You want to parse these files jointly, generating an XML output file containing the employee names and salaries. You can configure the transformation in the following way:
  • The main Parser, called
    EmployeeParser
    , processes
    IdsAndSalaries.txt
    .
  • The main Parser activates a secondary Parser, called
    IdsToNamesParser
    , which processes
    IdsAndNames.txt
     and stores the result in an XML table.
  • The main Parser uses a
    LookupTransformer
     to convert the IDs to names. The lookup table is the output of the secondary Parser.
The following figure shows an example of a Script with a secondary Parser that references an
AdditionalInputPort
 to retrieve the
IdsAndNames.txt
 file:
Global level EmployeeParser = Parser >> Level 1 example_source = LocalFile >> Level 2 file_name = IdsAndSalaries.txt Level 1 format = CustomFormat() Level 1 contains line Level 1 RunParser >> Level 2 selected input_source_as_text Level 2 next_Parser = IdsToNamesParser Level 2 input_source = $IdsToNames Level 1 RepeatingGroup() Level 1 ... Global level IdsToNames = Variable() Global level IdsToNamesPort = AdditionalInputPort >> Level 1 data_holder = $IdsToNames Level 1 input_encoding = ... Level 1 example_source = LocalFile >> Level 2 file_name = IdsToNames.txt Global level IdsToNamesParser = Parser >> Level 1 example_source = InputPort Level 2 Port = IdsToNamesPort Level 1 format = CustomFormat() Level 1 contains line Level 1 RepeatingGroup()
