Regex Trigger for a Text File---Am I missing something?

[tjfoth]

LOVE THIS APP!!!

I'm new... but for the most part, with this ONE exception, everything is working fine!

I am monitoring the US National Weather Service for alerts. The links I'm using with ChangeDetection.io point to text only pages/files.

For example:

https://tgftp.nws.noaa.gov/data/raw/no/nous42.kwno.adm.sdm.txt

points to a page where SOMETIMES a report like the following comes in. I want to key off the words CRITICAL WEATHER. The file returned by the link appears exactly, with no HTML, as below between the $$$ lines.

NOUS42 KWNO 270853

SENIOR DUTY METEOROLOGIST NWS ADMINISTRATIVE MESSAGE
NWS NCEP CENTRAL OPERATIONS COLLEGE PARK MD
0853Z MON JAN 27 2025

CRITICAL WEATHER DAY STATUS...
Critical Weather Day is not expected in the next 3 days.

CRITICAL WEATHER OUTLOOK...
Monday - None.
Tuesday - None.
Wednesday - None.

Liddick/SDM/NCO/NCEP

I am using the following regex which matches when I try it in the BBEdit editor which supports regex (I never trust myself to decode complex regex):

(?:^|\W)critical\sweather(?:$|\W)

It doesn't appear to be matching. I'm not sure what to set the CSS/JSONPath/JQ/XPath Filters field to: right now it is blank.

Am I missing something?

Thank so much for someone's support!

Can you explain what it is you want to achieve exactly?

[tjfoth]

Thanks for your incredibly (actually unbelievably incredibly) fast response! I would like to be notified of changes to that text file ONLY when the words CRITICAL WEATHER occurs (and I want to set up another rule about when the word API occurs). I am not concerned about other postings they make concerning when different forecast models are running.

Just put CRITICAL WEATHER in the Trigger/wait for text box

You dont need any regex

[tjfoth]

That one I'm okay with. That combination of words is probably pretty unique. What about API, however? I'm afraid of API being caught up as part of a larger work that includes the letters API (example: rapid, which is word used describing storm system development).

so put in the Trigger/wait for text box

SOMETHING INTERESTING
/\sAPI\s/

[tjfoth]

Thanks so much! I’ll give that a try. —- Tom Foth ***@***.***

see here, I'm using a regex to find .gov and a space either side, it doesnt match the other ".gov" content

[tjfoth]

Thanks for pointing this out to me. The more complex regex I offered takes into account it being the first thing on the line or the last thing. I suspect an easier way of doing that would be: ^API\s \sAPI$ \sAPI\s Given that you mention those lines are basically "ORed" together.

Actually, it appears ^ and $ are not respected. I've tried patterns where there is a line break, like .THURSDAY NIGHT...Partly cloudy. Near steady temperature in the lower 20s. to match the lower or thelower and they don't match, suggesting that the regex is seeing something there. Likewise the$ does not match.

Nevermind.... I see I forgot to put slashes around the regex. We can mark this closed.
