Wildcard Route All ADT_A?? except A17 and A24.

[Keith McLeod]

I have gone through several regular expressions in a wildcard route, however still not getting the reulst of sending all ADTs except ADT_A17 and ADT_A24 message types.  Tried things like ADT_A.[^17|24] and other variations.  Is the ‘.’ required?

Anyone have a good source for regular expression building?

A good source is Brent Welch’s latest Tcl book.

When you say *ALL* HL7 message do you really mean all?  

You could use a regexp like:

ADT_A(0[1-9)|(1[0-689])|(2[0-35-9])|(3[0-9])

Would send ADT_A01 – ADT_A39 and exclude A17 and A24

If I really wanted all and I was just getting ADTs, I would filter the A17 and A24 types in the input and simply raw route the rest.

There’s a tool called Visual-Regexp which allows you to play around with regular expressions and matching.  I use it every now and then when I’m working on a tricky one, or when the regular expresssion I just created somehow fails to match anything.

See http://wiki.tcl.tk/7992 for details.  The interface takes a little getting used to, but once you get the hang of it…

Don’t confuse with Regexplorer, which is a similar tool written in Perl.

We also have a tool called Tcl   8)

I should probably clarify that Visual-Regexp IS written in TCL, which is why I tend to use it for TCL regular expressions.   Regexplorer is probably just as good for regular expression exploring, but it’s written in Perl…
