Strip all punctuation from a text input

I'm trying to allow my users to paste whole paragraphs of text into a text box, which I then need to parse without any punctuation. I'm happy with the parsing, but not sure of the best way to remove punctuation.

 

Looking at the Substitute function, and thinking back to my InfoPath days, it doesn't let you replace characters by position. So for example I can't list all the characters I want to remove and 'replace' them with a blank string.

 

I guess I could nest a bunch of substitutes as below, but this feels inefficient.

 

Substitute(Substitute(Substitute(TextInput1.Text, ".", ""), ",", ""), ";", ""), etc.....

 

Any thoughts?

Instant solution!

 

In case anyone finds this, save yourself a hop with the following:-

 

Concat(Filter(Split(TextInput1.Text,""),IsMatch(Result, "^[a-zA-Z0-9]*$")),Result)
