[Anonymonk]: In common with previous respondents, I can't understand your problem (just what does "doesn't seem to work" mean?) with the code given in the OP: it does just what I understand you want done. Please see example below. (I use 'H' in place of '#' because my little command line editor thinks all #s are comments. Also, I give an alternate approach that I think might be more flexible. It could even be done without captures, but let's not get ahead of ourselves.) 

>perl -wMstrict -le
"my $text = 'foo size=\"10\">HHili1 bar size=\"10\">HHili22 baz';
 print qq{'$text'};
 ;;
 $text =~ s/size=\"10\">HHili(\d{1,2})/size=\"10\" text-anchor=\"end\"
+>HHili$1/g;
 print qq{'$text'};
 ;;
 my $toxt = 'fee size=\"10\">HHili1 fie size=\"10\">HHili22 foe';
 print qq{'$toxt'};
 ;;
 my $pre  = qr{ size=\"10\"   }xms;
 my $post = qr{ >HHili\d{1,2} }xms;
 my $insert = ' text-anchor=\"end\"';
 $toxt =~ s{ ($pre) ($post) }{$1$insert$2}xmsg;
 print qq{'$toxt'};
"
'foo size="10">HHili1 bar size="10">HHili22 baz'
'foo size="10" text-anchor="end">HHili1 bar size="10" text-anchor="end
+">HHili22
baz'
'fee size="10">HHili1 fie size="10">HHili22 foe'
'fee size="10" text-anchor="end">HHili1 fie size="10" text-anchor="end
+">HHili22
foe'
