index with regex

I'm trying to find a way to get the index (i.e. start position in a string) for a regex pattern. I can use text, replacex, extractx for various operations but not for getting the index, and the index function does no allow regex patterns.

    You can use the extractx function in the index function. You can see an example of this here...

    You can do this in two stages: 

    extract text using a regular expression 

    find the position of the result text using the index function :

    var myText := "ABC123";
var myRegExp := "\d+";
var textResult := extractx(myText, myRegExp);
var position := index(myText, textResult);
myText + " | " + textResult + " | "+ position;

    return : ABC123 | 123 | 3

       You can also make it a one-liner...

      index("ABC123", extractx("ABC123", "\d+"))

    Or maybe:

    length(replacex(<your input string>, "<your regular expression>[^]*", ""))

    Ah, smart, thanks! I did something similar, but way less efficient
