Thanks Jonathan for this great regular expression for offline structure controls that allows me to do a pre-check but here I would like to check the existence of this URL in an RPG program.

Hello everyone

I need to control that a URL entered by a user is valid.
Would anyone have an example of RPG code for this?

I'm going to have to say that regex might be the best way (I know nothing about regex) as there are a good few examples on the interwebby.
(https://www.regextester.com/98055)

Likewise, there are examples of using regex from within RPG such as via SQL (possibly others, maybe C, or an API?).

The expression required is (remove quotes) "(ftp|http|https):\/\/(\w
+:{0,1}\w*@)?(\S+)(:[0-9]+)?(\/|\/([\w#!:.?+=&%@!\-\/]))?"

Hope this helps.

Jean-Marc DUVAL
