perl regular expression not inbetween issue
Dear All,

Code:
perl -e 'if($ARGV[0] =~ /\A^[0-9]{10}\z/){print "Valid string\n"}else{print "Invalid string\n"}' '1234567899'
Valid string

perl -e 'if($ARGV[0] =~ /\A^[0-9]{8}\z/){print "Valid string\n"}else{print "Invalid string\n"}' '12345678'
Valid string

individually both works, anyway to combine both together? the outcome should be "Valid string" when the length eq 8 or 10, but not 9, so i cannot use {8,10} as it includes 9.

Thanks
