StringRegExpReplace remove single character between 2 numbers

Recommended Posts

Aktonius

I am trying to remove comma between 2 numbers and return updated string but this code bellow will remove entire string instead, how can i do this that updated string will just remove comma?

Here is what i tried

StringRegExpReplace("1,2", "\d(.*?)\d", "", 0)

and then it returns blank

 

What confuses me is that  the code bellow perfectly returns comma as array match 

StringRegExp"1,2", "\d(.*?)\d", 1)

So if the same regex is used as pattern in the StringRegExpReplace why is entire string replaced and not just comma?

Cant believe that i am stuck on something stupid as this :(

StringReplace will accept a variable as it's first parameter, you know..

You bet. I'm sure you will receive more replies. My Regex knowledge is way low. Good luck.

Try this.

ConsoleWrite(StringRegExpReplace("Now is the time, for all good men, to come to the aid of their country. 3333 333 335,26 6666 6666 6666 66,666", "(\d+),(\d+)", "\1\2") & @CRLF)
This will take a string and remove the commas between all sets of numbers that have commas in between them. If there are no commas, it just returns the numbers and/or text. You will also notice that it's not removing the commas in the text portion. Edited by BrewManNH

Aktonius,

In the replacement pattern, 1 (or $1) stands for the content of the first captured group, 2 (or $2) the second, and so on.

You can achieve the same result without capturing and replacing. Using look-behind and look-forward assertions (both are non-capturing) is enough to insure the comma is matched when you want only and replaced by an empty string.

ConsoleWrite(StringRegExpReplace("Now is the time, for all good men, to come to the aid of their country. 3333 333 335,26 6666 6666 6666 66,666", "(?<=\d),(?=\d)", "") & @CRLF)
