Splitting a string to extract numbers

[#1]

Hi , 

I have a string that is character and I want to extract a 4 number section. The position of the numbers may change

An example of the string may be

value ="Hello 0123 example";

I have tried this but only works if the numbers are in the correct position. 

value ="Hello 0123 example";

extract=substr(value,7, 4);

As the position of the number will change how can I extract this?

You could try something like this:

Names Default To Here( 1 );

string = "Hello 0123 example";
matches = Regex Match(
	string,
	"[0-9]{4}",
);
// ASSUMES that you are interested only in the first 4-digit number, if there is more than one
extractedNumber = matches[1];

This returns "0123".

Please note that it still returns "0123" if your input string is "Hello 01234 example".

This worked like a charm. Thank you so much!

One other option is to use Regex instead of Regex Match (there are also more options how this could be done, but I think Regex and Regex Match are the easiest ones)

Names Default To Here(1);

string = "Hello 0123 example";
four_num = Regex(string, "\d{4}"); //0123

See https://regex101.com/r/26hBdb/1 for how regex this works if you are not familiar with it.

This is probably better because you don't have to grab the first match.  Thanks!
