Problem replacing CRLF with .br for ORU formatted text

[nshaik]

Mirth 1.3.1, Java 1.5_09 Windows XP Pro
==========

Need to replace "Carriage Return" and/or "New Line" with "\.br" for ORU Transcription Formatted Text.

========= Transformer JavaScript Step =========

var tempString = "Line1\nLine2\r\nLine3\nLine4\r\nLine5\n";

tempString = tempString.replace(/[\r\n]/g, "\\.br\");
=====================================

I get tempString as

==========
Line1\E\.br\E\Line2\E\.br\E\\E\.br\E\Line3\E\.br\E \Line4\E\.br\E\\E\.br\E\Line5\E\.br\E\==========

I have tried various differnt ways but just keep getting "\E".

I tried the same JavaScript in a Test.html web page and it works fine (I don't get the \E).

Any help to resolve this problem would be appreciated.

Thanks in advance

Try:

tempString = tempString.replace(/[\r\n]/g, "\.br");

Chris,

Thanks for the quick reply. I tried that before and tried it again (Did a copy and paste from the reply).

"\.br" appears in red font and "Validate JavaScript" thorws error:

==========
Error on line xx: unterminated string literal.
==========

If changed to "\\.br\" the font changes to purple and JavaScript validation goes through successfully but get "\E" in the output.

Re: Problem replacing CRLF with .br for ORU formatted text

try adding a replace for \E with ""

Re: Problem replacing CRLF with .br for ORU formatted text

Chris,

I tried that as well but the output still has \E.

The problem appears to be with Mirth. Inside a javascript transformer step, if a string variable has a backslash Mirth is replacing it with a \E.

To confirm this, here's what we tried:

1. Removed the CRLF replace statement in the Mirth Transformer.

2. Did the actual CRLF replacement to "\.br" on our server side code which saves the document in the database.

3. When I copy and paste the data from SQL Server 2000 column to Notepad or any text editor I see just the "\.br" where expected.

4. But when the document is read by Mirth (with no replace for CRLF to "\.br") and outputs an ORU transcription message it adds a \E for each backslash. That is, instead of "\.br" we get "\E\.br\E"

Could it be related to Encoding?

In the "Destination" tab it was set to "default". Tried US-ASCII and also windows-1250 but it did not help.

I appreciate all your help!

Thank you.

Re: Problem replacing CRLF with .br for ORU formatted text

More info. to help reproduce the problem.

==== Transformer JavaScrit test code ========
var tempString = "Line1\\.br\\Line2TestPatient\\.br\\Line3\\.br\\Li ne4";
logger.info('tempString is: ' + tempString);

Note: logger.info works fine and shows the correct output.

But the output HL7 Message from Mirth does not ( puts a \E ):

Re: Problem replacing CRLF with .br for ORU formatted text

Whre is the '\E' added.. ¿after the preprocessor or after the processor?

[nshaik]

Re: Problem replacing CRLF with .br for ORU formatted text

It's an Outbound "Database to File Writer" Channel. The "\E" gets added when the message is written out to the file (it does not happen when you print it out in mirth.log file using logger.info)

Thanks

[chrisl]

Re: Problem replacing CRLF with .br for ORU formatted text

Ah yes. Because \ is an encoding character, the HL7 encoder uses \E\ to denote \. If you change the encoding character it should operate as expected.

Re: Problem replacing CRLF with .br for ORU formatted text

Chris,

Thank you very much for your reply. Where do I change the encoding character and to what character?

Thanks

[chrisl]

Re: Problem replacing CRLF with .br for ORU formatted text

You can change it in the preprocesser (message.replace...) Change it to '*'. You then must change it back after the transformation happens. Use the "ER7 Encoder" (serializer) in the transformer to convert the msg or tmp XML to ER7.

Re: Problem replacing CRLF with .br for ORU formatted text

I get "Failed to invoke UMO Component" error.

Could you please let me what needs to be corrected? Thanks for your help.

Here's what I tried.

=======================
Summary Tab:

Preprocessing Script:

// Modify the message variable below to pre process data
message.replace(/[\E\]/g, "*");
return message;
=======================

Destinations Tab / Edit Transformer / Added a new JavaScript Step (Last Step)

message = message.replace(/[\*]/g, "\\E\");
serializer.fromXML(message);
========================

Re: Problem replacing CRLF with .br for ORU formatted text

message.replace(/[\\E\\]/g, "*");

Re: Problem replacing CRLF with .br for ORU formatted text

Chris,

Thank you for the reply. When I made the change and tried again, I get, "Error at tranformerorg.mule.umo.transformer.TransformerExce ption: Wrapped java.lang.NullPointerException (56ea1d1d-28f8-4728-8d89-924af57e2860#70) (org.mozilla.javascript.WrappedException)" exception.

logger.info(&#039;tempString is: &#039; + tempString.toString());
inside the transformer JavaScript steps show the text correctly.

It is only when Mirth tries to send the outbound message I get this error.

I would appreciate if you could help resovle this problem.

Thanks

Re: Problem replacing CRLF with .br for ORU formatted text

Let&#039;s try a different approach -

1) Replace "" in the preprocessor (in the message header):

return message.replace(/ ~ \ \ /,"~*"):

NOTE: REMOVE THE SPACES IN THE FIRST REPLACE PARAMETER (THE FORUM SOFTWARE WAS CAUSING ISSUES)

2) In the Javascript, perform your modifications and serialization as unnecessary. Let&#039;s assume we store this in a var called "er7".

3) Replace the * in the msh header with "":

er7 = er7.replace(/~\*/,"~\");

(You might just need "~" in that last replacement.)

This will cause the message mirth reads in to treat * as an encoding character (so that \ will not get replaced). In your file writer, make sure you specify "${er7}" as the output variable.
