I am trying to write a regular expression that can extract (possibly several) strings of four hexadecimal numbers / letters.
I could do something like this:
/^[A-Fa-f0-9][A-Fa-f0-9][A-Fa-f0-9][A-Fa-f0-9]/
but is there a better way?
The repeat statement seems to be:
a {n} Matches 'a' repeated exactly n times.
a {n,} Matches 'a' repeated n or more times.
a {n, m} Corresponds to 'a' repeated between n and m times inclusive.
Will work, but the following regex does not work:
/^[A-Fa-f0-9]{4}+/
I am trying to match strings, for example:
AA00
AA00FFAA
0011FFAA0022
etc. Each line will be on its own line.
Thank!
