RegEX Regular Expression & Formula string\match

[espcrm]

I'm playing with the "big" league now! Playing with regular expression!

Anyway I'm not sure if this is possible with EspoCRM, anyone do something similar or have the knowledge?

I got a street address like so:

123 Main Street, Suburb City 2000

Style as
[Street number Street name and Street type], [City name] [Postal code]

Using the regex I found online like so I can get all data in different group like so: (tested with https://regex101.com/)

Regex Code

/\b(\d+\s+[\w\s]+)\s*,?\s*(\b(?:Road|Street|Avenue|Lane|Drive|Boulevard|Crescent|Court|Place|Terrace|Highway|Parade|Close|Grove|Way|Walk|Esplanade))\b(?:\s*,\s*)?(\b[A-Z][a-z]+\b(?:\s+[A-Z][a-z]+\b)*)?\s*(\b\d{4})\b/

Test Data:

123 Main Street, Suburb City 2000

As you can see it is working and it have separate the data into different group


Now what I want to do next using the formula is this:
adddressStreet = (group1)
addressCity = (group2)

For example:
addressStreet = '123 Main'

Formula wise it will look something like this:

output\printLine(

ifThen(formulaHelper!=null,
    addressStreet=string\match(formulaHelper, '/RegEX Group 1 here/');
    addressCity=string\match(formulaHelper, '/RegEX Group 3 here/')

formulaHelper is just a custom field so I can paste data and it "extract" data for me.
Of course the example above will not work! Because I don't know the correct code.

And here I am, asking. Thank you.

Using the match function, you can't retrieve groups 2, 3, etc. If you want to access a group other than the first one, you should create your own function. If I understood the question correctly, that is.

Thank you dimyy! I guess I need to look at that code and add $matches[1];

Anyway this is a big clue and tips!
