Regex - parsing text after third appearance of sign "$"

Posted on by PawelSlon

Hi,

I have a following text:

"$1234 $2345 $3456"

What I need is to parse a number appearing after third appearance of the sign "$", which is "3456".

I used regex working on regex101:

...but in PAD this one results in "0".

I had couple of other options. Below regexes and results in PAD:

^(?:[^$]*\$){3}(.*) result: "0"
(?:[^$]*\$){3}([^$]*) result: "0"
\\$(.*) result: "0"
(?<=([^$]*\$){3})\s*(.*) result: "13"
(?<=([^$]*\$){3}).* result: "13"

I also played around with removing white spaces in "$1234 $2345 $3456" before applying regexes.

Actually, I figured out, that I can simply parse three times text appearing after "$", but still, it bothers me that none of these regexes parsing text after third appearance work. Also, I don't know how big the project will be, so it would be cool to have one line of code, instead of three to have it done.

Many thanks for any ideas!

Hi Pawel,

I recommend using ChatGPT generate your regex for your business requirements.

This solution was provided by ChatGPT and it has been working well for me.

Regex:

\d+(?=[^$]*$)

Hi Deenuji_Loganathan_,

thanks for your answer.

I was looking for that solution using Perplexity.ai, regex101.com, as well as stackoverflow.com. Will add chat GPT to my sources:)

Your solution is interesting, though it gives me result "13" in PAD. Though it works on regex101:/ Is it a PAD issue?

Regards,

Paweł

@PawelSlon

I think you are looking at the wrong output variable. You are looking at the "Position" which just returns the position which the text is found. Look at the Match variables value and it should be same as in Deenuji_Loganathans, picture: 3456

ps. I think you should mark Deenujis answer as the solution
