regex - Regextract Google Spreadsheet - Extract text from multiline string -

i have same issue of this post

but i'm using google spreadsheet. though it's not considered "programming" topic, regex syntax same.

i need extract text between 2 tags. eg:

start sample text end

when apply regex syntax works:

"start(.*)end"

but if sample text contains new line not. hints?

if want rid off new line character, 1 solution replace new line character "", e.g:

=regexextract(regexreplace(a1, "\n", ""), "start (.+) end")

if want keep new line character, try:

=regexextract(a1, "start (\w+\n\w+) end")

alternatively if want solution works strings , without new line character, try:

=regexextract(a1, "start (\w+|\w+\n\w+) end")

Unity
