Regex in SMAT for when a segment does not exist

[Danny Wheeler]

I am trying to write a regex to search the SMAT files for when a message does not contain an OBX segment.  Has anyone ever done something like this?

How about using

“Not Include Those” and use rOBX as the regular expression?

Of course, are you using the SMAT viewing tool or outside of that?
