SMAT Regular expression matching in 5.8.4

[mark zebehazy]

Good afternoon all,

Ran into an interesting issue today regarding searhing SMAT files using regular expressions.

In 5.7, I could use the following regular expression to find all HL7 messages with an MSH.4 value of 052 and a DG1 segment:

|052|.*DG1

In 5.8.4, if I use this same expression, it will not return any results. Doing more research, I found if I put this expression in 5.8.4, it does work:

|052|.*r.*r.*r.*rDG1

So what appears to be happening is that the carriage return is no longer considered matching the . in the regular expression.

We looked through the release notes for 5.8.5 and didn’t see that this was corrected. Is this an issue or does someone have a better expression to use in 5.8.4’s regular expression tool?

Thanks,

Mark Zebehazy

|052|(.*r)*DG1

This way, the DG1 doesn’t have to be a set number of lines below the 052.

Thank you Bill, that’s a great suggestion.
