IsLike Function:
Compares a string to a regular expression.
Description:
The IsLike function compares a string using a regular expression and returns True if the regular expression matches the input string or False if the pattern doesn't match.
There are two required arguments, string and pattern.
String is the string to compare.
Pattern is the regular expression to apply to the string.
Returns Null if error handling is enabled and a problem is encountered during comparison.
Syntax:
boolean = IsLike(string, pattern)
Example:
<%
'--- IsLike returns True to indicate a pattern match.
response.write IsLike("Livio Siri", "[A-Z]\D\D\D\D\s[A-Z]\D\D\D")
'--- IsLike returns False to indicate no pattern match.
response.write IsLike("Livio Siri", "B[^i]")
%>
