## Target String:

## Example: target1 ^.. regex [r|hoge[0-9]+|]
[MatchPart {_matchedString = "hoge00", _captures = []},MatchPart {_matchedString = "hoge01", _captures = []},MatchPart {_matchedString = "hoge02", _captures = []}]

## Example: target1 ^.. regex [r|hoge[0-9]+|] . matchedString
["hoge00","hoge01","hoge02"]

## Example: target1 ^? regex [r|hoge[0-9]+|] . index 1 . matchedString
Just "hoge01"

## Example: target1 ^? regex [r|hoge[0-9]+|] . index 3 . matchedString
Nothing

## Example: target1 & regex [r|hoge[0-9]+|] . matchedString .~ "HOGE"
"HOGE fuga HOGE neko HOGE"

## Example: target1 & regex [r|hoge[0-9]+|] .index 1 . matchedString .~ "HOGE"
"hoge00 fuga HOGE neko hoge02"

## Example: target1 & regex [r|hoge[0-9]+|] .index 1 . matchedString %~ (\s -> "<<" ++ s ++ ">>")
"hoge00 fuga <<hoge01>> neko hoge02"

## Target String:
target2 = "<img src=\"/image/shinku0721.jpg\" alt=\"shinku birthday\"><img src=\"/image/shinku141.jpg\">"
