Per perlre:

"(?<NAME>pattern)"
A named capture group. Identical in every respect to normal
capturing parentheses "()" but for the additional fact ...

Don't know if this helps much, but if you already know the ordinal number of the capture group associated with a named capture, then @- @+ work exactly as advertised. (But it sounds as if you want to go from the named group to its capture group ordinal.)

>perl -wMstrict -le
"my $s = 'xxx fooooo yyy';
 ;;
 $s =~ m{ (x+) .*? (?<FOO>fo+) .*? (y+) }xms;
 ;;
 print qq{'$1'  '$+{FOO}'  '$3'};
 print qq{'$1'  '$2'  '$3'};
 print qq{/fo+/ at $-[2] to $+[2]};
"
'xxx'  'fooooo'  'yyy'
'xxx'  'fooooo'  'yyy'
/fo+/ at 4 to 10

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
