    Trailing white space on version number

    Hi,

    I just tried to process an ADT message with v1.3. I receive an exception and the problem stems from a trailing white space on the version number. It's '2.1 '. If I manually trim the trailing space the message is processed. (I just store it to a file for now.) I don't have control over the ADT system so I can't fix it there. Is there a way to remove the trailing space before the exception occurs?

    Re: Trailing white space on version number

    You can use the preprocessor:

    Code:
    message = message.replaceAll("|2.1 ", "|2.1");
    (or you might have to do)

    Code:
    //regex version for js message
message = message.replace(/\|2\.1 /g", "|2.1");
    That's assumign it's |2.1
    Just remove the | if you have issues.

      Re: Trailing white space on version number

      That space might actually be a \r or \n

      In that case, do
      Code:
      message = message.replaceAll("|2.1\r", "|2.1"); //or \n

        Re: Trailing white space on version number

        Thanks for the quick reply. I tried doing the replaceAll but with no luck. I received a different exception. This one says the "Cannot find function replaceAll". Could it be I put this little bit of code in the wrong place? The code is below. I tried just replacing the space and then the newline and carriage return individually. I put in the code below with all three replaceAll() calls just to ensure it wouldn't miss a condition. This code in the Edit Channel page in the "Preprocessing Script" section. This is correct, isn't it?

        // Modify the message variable below to pre process data
        message = message.replaceAll("|2.1 ", "|2.1");
        message = message.replaceAll("|2.1\n", "|2.1");
        message = message.replaceAll("|2.1\r", "|2.1");
        return message;

            Re: Trailing white space on version number

            Ok. I changed it to:

            message = message.replace("|2.1 ", "|2.1");

            I have the output as a text file of the transformed data. The file gets created and it all seems correct but the exception below gets generated even though it looks like everything is ok. Am I misunderstanding something? I am simply having incoming LLP messages written out to a text file.

            p.s. The responses have been great. Quick and on the mark.

              Re: Trailing white space on version number

              Hmm...quite an interesting error. It appears this may be an error on the HAPI side or the message might be invalid. Thankfully the preprocessor will let us get around that. Try changing 2.1 to 2.2 - HL7 v2.1, 2.2 and 2.3 are very similar (with 2.3.1, 2.4 and 2.5 introducing several changes).

                  Re: Trailing white space on version number

                  It still seems to have to do with the trailing space on the version number. If I trim the space manually in a text editor the message gets processed fine but like I said, the message comes from an ADT system that I don't control. The message is below but I'm not sure that cutting and pasting is here will give you the same result. Let me know if you need the channel. It's very simple. It receives the message LLP and then simply write the message to a file.

                  Thanks.

                    Yo can try:

                    message = message.replace("|2.1", "|2.1|");

                    If it doesn't work, please, send me the message to albersato *at* gmail *dot* com

                      Re: Trailing white space on version number

                      It might not be an actual space - it might be a control character (vertical tab, line feed, carriage return, etc).

                      You can try using a regex in the replace command - Google Javascript string replace regex. The format is similar to:

                      Code:
                      message = message.replace(\2\.1\w*\g,"2.1");
                      (I think \w is to capture any whitespace char, but I might be mistaken. The entire expression needs to be surrounded by \ \ and any special characters (| . * { } ( ) [ ] ^) needs to be escaped with a \. Also you should include 'g' at the end to express that you'd like a global search and replace in the string.

                        Re: Trailing white space on version number

                        Ok, this is the final solution (tested):

                        Code:
                        // Modify the message variable below to pre process data
message=message.replace(/\|2\.1 /i,'|2.1|');
message=message.replace(/[^\r]PID\|/i,'\rPID');

return message;
                        In the message there are two problems: the version, and the lost of '\r' in the PID segment.
