Hi Fursat,

 regexmatch(
                      pattern: "^\s*[A-Z0-9\'\+\&\%_-]+(\.{0,1}[A-Z0-9\'\+\&\%_-]+)*[@]{1}[A-Z0-9.-]*[A-Z0-9-]+[.]{1}[A-Z]{2,6}\s*$",
                      searchString: ri!email
                    )

The above regular expression will allow you to add white space at start and end.

Try this and let me know if it works for you.

True. Feel free to adapt the code to do whatever you need it to do.

you'll need to share what you've tried if you hope to find additional help with getting a validation message to show up. this is not much info to go on.

I have an expression rule where I added ~18 extended test cases - edge cases to try to break the validation function - a while ago I developed a RegEx that handles all of them, and the plug-in rule (which came later iirc) handles all of them as well. I switch back and forth regarding which version to use - i haven't noticed any major performance difference between them (and they both use a plug-in ultimately so it's not like either version saves a dependency).

I try to use the built-in Appian function for this as well. If that is not enough, I'll look at a regex solution.

in that code, if we enter incorrect email address format it is not throwing any validation error,it is saving only correct email address for incorrect ones nothing is displayed as error

Depending on your actual use case, this might be a good fit.

You can try this:

regexmatch(
                      pattern: "^[A-Z0-9\'\+\&\%_-]+(\.{0,1}[A-Z0-9\'\+\&\%_-]+)*[@]{1}[A-Z0-9.-]*[A-Z0-9-]+[.]{1}[A-Z]{2,6}$",
                      searchString: ri!email
                    )

For validating an email address you can certainly contrive a complex regular expression to test for validity, though these days I just recommend using the "validateEmailAddress()" rule found in, i think, People Functions.

As far as "line delimited" - you'll need to implement your own parsing / checking for that part, depending on exactly what you want. It could be as simple as splitting the input on the linebreak character (char(10)) then validating each (non-empty) line in the resulting set - that would simply require looping over the validate email function.

OK, and what is the question? For using regular expressions, you can use the plugin Regular Expression Functions from App MArkt....
