vim yank all matches of regex group into register

I know that I can yank all matched lines into register A like this:

:g/regex/y/A

But I can't seem to figure out how to yank match regex groups into register A:

:g/\(regex\)/\1y A
(E10: \ should be followed by /, ? or &)

I like this solution, it also places a newline in-between each match:

:let @a='' | %s/regex/\=setreg('A', submatch(0) . "\n")/n

Wouldn't work for me with the /n flag - got nothing in the register - and without it vim did the substitute on the line.

Ended up with:

:g/pat1/s~pat2\\(regex\\)pat3~\=submatch(0).setreg('a',submatch(1))~

which seemed to do what I wanted.

You can also yank all matched line between two sessions to pointed register.

By way of example:

:11,21s/regex/\=setreg('A', submatch(0))/n

Matches regrex group from line 11 to line 21 rather than the whole file. 

:/^ab/,/^cd/s/regex/\=setreg('A', submatch(0))/n

Matches regrex group from the line that stards with ab to line with cd.

If you just want to grab one part of the match, you can work with \zs and \ze. You need capture groups only for multiple parts, or reordering.

My ExtractMatches plugin provides (among others) a convenient :YankMatches command that also supports replacements:

:[range]YankMatches[!] /{pattern}/{replacement}/[x]

You can do this with a substitute command.

:%s/regex/\=setreg('A', submatch(0))/n

This will append register a to whatever the regex matched. The n flag will run the command in a sandbox so nothing will actually get replaced but the side effects of the statement will happen.

You probably want to empty the register first with 

:let @a=''
