ismatch

ismatch(r::Regex, s::AbstractString) -> Bool

Test whether a string contains a match of the given regular expression.

Examples

1. Check if a string matches a regular expression:

   julia> regex = r"a[bc]+d";
   julia> ismatch(regex, "abcd")
   true

   This example checks if the string "abcd" matches the regular expression r"a[bc]+d". The function returns true because the string matches the pattern.

2. Verify if a string does not match a regular expression:

   julia> regex = r"[0-9]+";
   julia> ismatch(regex, "abc123")
   true

   This example checks if the string "abc123" contains a match for the regular expression r"[0-9]+". The function returns true because the string contains digits.

3. Validate if a string matches a specific pattern:

   julia> regex = r"^[A-Z][a-z]+$";
   julia> ismatch(regex, "Julia")
   true

   It checks if the string "Julia" matches the regular expression r"^[A-Z][a-z]+$", which represents a string starting with an uppercase letter followed by one or more lowercase letters.

Common mistake example:

julia> regex = r"[0-9]+";
julia> ismatch(regex, "abc")
false

In this example, the string "abc" does not contain any digits, so it does not match the regular expression r"[0-9]+". The function correctly returns false in this case.
