Here in my text to find matches of ALL "hci" in it:


So based on your sub - reply to me

"Devices:\n\thci1\t00:50:B6:80:4D:5D\n\thci0\t00:15:83:15:A2:CB\n"


What you actually want is the following

hci 00:50:B6:80:4D:5D
hci 00:15:83:15:A2:CB


Your text sample represents a multi-line input presumably with tab separators.

From that sample it is actually pointless to use a regex since normal parsing (or csv parser would work.)

But in terms of Regex you have several problems
1. Dealing with multiple lines
2. Correctly matching the values.
3. Dealing with special characters (including perhaps #1 above.)
4. Dealing with a list of results - as I stated in my other reply.


So your regex is not even close to correct for matching the address.

Looking at 2 only because that is the part most likely to be usable as a regex the equivalent regex for Perl would look like the following. Since you are not using Perl yours might vary but I suspect not.

(hci\w+([a-fA-F0-9][a-fA-F0-9]:)+[a-fA-F0-9][a-fA-F0-9])


There are variations on the above
- Making the tab explicit
- Restricting the id to the exact length
- variation on the hex digit but I prefer the above form
