ToDo:

Use an Edit Data --> Replace Text action in the workflow.

Select Regex option and replace by empty string.

You can also replace the match with any string you require.

 

Get Handles:

(^|\s|[^@\w])+[^@\s]+

Example: Hi @Something how are @you doing David.

Result: Hi how are doing David.

 

Remove Hashtags:

(?=(#\w+\b))

 

Example: Hi #Something how are #you doing David.

Result: Hi how are doing David

 

Get a word or phrase:

\b(?!cat\b)\w+

Example: This cat is beautiful!!

Except a word or phrase:

Hi NFSharma,

Thanks for sharing these formulas.

Do you have anything for the last 2 formulas for all characters before and after, for a multi-line field ?

I've tested this out on Regex101 website

^(?!Numbers:).*

and it works, removing all text except for the bold text below, but does not work in Domo,

Hi @Domofied

If you have Magic ETL 2.0 you can use the regex_replace function to pass in processing flags - this isn't possible with the ETL 1.0 Replace Text tile. By default regex101 as the g (global) and m (multiline) flags enabled whereas Domo does not. Passing in the 'm' as the third parameter should resolve your issue.

REGEXP_REPLACE(`note`, '^(?!Numbers:).*', '$1', 'm')

Hi Grant,

That makes sense ! Hahahahaa 😂

I'm currently working with ETL v1.0 so would there be any possible work arounds to handle multi-lines ?

Cheers!

Hi @Domofied

You might be able to do this as a calculated field in a Dataset View but because you're on ETL 1.0 you wouldn't be able to use it as an input into your dataflow. It'd have to be your last step before you visualize your data.
