In this case we can also use a character class which excludes closing
square bracket:
irb(main):004:0> [str1,str2].each {|s| printf "%s -> %p\n", s,
s.scan(/\[Subject:\d+\|([^\]]*)\]/)}
Hi, @[Subject:13|My_Subject] -> [["My_Subject"]]
Hi, @[Subject:13|My_Subject], and @[Subject:45|Your_Subject] ->
[["My_Subject"], ["Your_Subject"]]
irb(main):005:0> [str1,str2].each {|s| printf "%s -> %p\n", s,
s.scan(/\[Subject:\d+\|([^\]]*)\]/).flatten}
Hi, @[Subject:13|My_Subject] -> ["My_Subject"]
Hi, @[Subject:13|My_Subject], and @[Subject:45|Your_Subject] ->
["My_Subject", "Your_Subject"]
Kind regards
