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.
