Regex matching first capital letter followed by one or more small letters

Question

That is my regular expression:

[A-Ö]{1}[a-ö]

When I write that everything is fine until I write another small letter it doesn\'t work. E.g.

Answer 1

[A-Ö]{1}[a-ö]*

The * means zero or more, if you require a lowercase letter to follow, then use

[A-Ö]{1}[a-ö]+

Answer 2

Note that [A-Ö] matches all lower and uppercase letters and a lot of other symbols, too.

You need

[A-ZÖ][a-zö]+

See regex demo

Note that + matches 1 or more occurrences of the preceding subpattern.
