Transformer : Message builder

[glesener]

Hello Everybody,

How can we use the transformer message builder ?
I try to use it to replace a string (for exemple the patient name) I put on the form the conditions :

message segment : "Change patient name"
Mapping : msg['PID']['PID.5']['XPN.1']['FN.1']
Default value : ""
String replacement : Regular expression : .* Replace with : "toto".

I always obtain a java exception. That's wrong ? Can you give me one example ?


Thanks,

Re: Transformer : Message builder

You need to create JavaScript Transformer step. In the Transformer screen, when you do "Add Step", you see a row with "newVar0" under column "Name" and "Mapper" under column "Type". Double click under "Type" it should show a list box with "Mapper" and "JavaScript" dropdown. Select "JavaScript".

Here's a sample JavaScript code.

// Get patient SSN with "-" removed
 var tempSSN = "";
if (pidSegment['PID.19'] != null) {
   tempSSN = pidSegment['PID.19'].toString();
   if (tempSSN.length > 0) {
       tempSSN = tempSSN.replace(/-/g, "");
  }
}
