RegexSearch expressions
The RegexSearch expression uses a Perl regular expression to check whether a certain string exists.
The first operand is the regular expression to match, that
is, the pattern to search for. The second operand is the value to
be analyzed. If the second operand is an array, the elements of the
array are searched for the regular expression in sequence until the
first match is found.
If a match is found, the return value is TRUE. Otherwise, the return value is FALSE. Missing or invalid regular expressions in the first operand result in an error.
For examples, see the topic about regular expressions.
