Help with Regex

[kengrubb]

I've been puzzling over how to make this happen, and I just know there's someone way smarter than me with Regex who can make this happen.

I want to do a Regex Search to find this:

• ^.{5}([^*].*\*isn|\*isn)

But not find this:

• ^.{5}([^*].*get +.*\*isn|get +.*\*isn)

If someone is wondering, I'm working in Natural, as in Software AG Natural.

^.{5}([^*].*\*isn|\*isn)

This is redundant and equal to ^.{5}((?:[^*].*)?\*isn)

But not find this

Use a negative lookahead: ^.{5}((?:[^*](?!.*get +).*)?\*isn)

I'm working in Natural, as in Software AG Natural.

Not sure why you say that, but I thought this board always relates to TextPad (and its regular expression abilities).

I should have been clearer. I'm using Textpad to search and view Natural code.

Use a negative lookahead: ^.{5}((?:[^*](?!.*get +).*)?\*isn)

I was thinking it should be negative lookbehind, but I haven't used them enough to really master them.

Getting hits on these strings using your RE.

Code: Select all

2580 GET RFRL-V *ISN(LABEL_3.)
1210 GET UPD-CLAIM *ISN (RD-CLM.)
1600 GET CLAIM *ISN (0980)

The ordering isn't quite right. Try
^.{5}(?!.*get )(?:[^*].*)?\*isn

[kengrubb]

The ordering isn't quite right. Try
^.{5}(?!.*get )(?:[^*].*)?\*isn

A great many thanks!
