 </mat-error>

Answer 1

我会使用：

^(?![1234]$)\d+$

说明：

^               # beginning of string
    (?!         # negative lookahead, make sure we haven't after:
        [1234]  # one of the digit 1 or 2 or 3 or 4
        $       # end of string
    )           # end lookahead
    \d+         # 1 or more digits
$               # end of string
