The new string intrinsic method IsMatch, with parameters pattern and result, can be used to deal with regular expressions for email address formatting.
For example to Validate an IP Address:
#STD_TEXT.IsMatch
Pattern("^(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$")
Result(#Label1)
#STD_TEXT = 12.13.14.15 will return TRUE, and #STD_TEXT = a.b.c.d will return FALSE.
The phrase regular expressions, and consequently, regexes, is often used to mean the specific, standard textual syntax for representing patterns for matching text. A regex pattern matches a target string.
