perl - all possible sub strings matching the regex -

i have string

<start><tag1><tag2><tag3><end>

if have regex <.*end> matches complete string , stops. there way gives matching substrings ike

<end> <tag3><end> <tag2><tag3><end> <tag1><tag2><tag3><end>

yes, must wrap pattern in lookahead (this way obtain overlapped results):

(?=(<.*end>))

the result in capture group 1.
