Regexps and HTML comments

Ruby
1

I have troubles with the regexp to get HTML comments ("") from a long (multi-line) string. Comments that have line breaks
aren’t found, only the comments that are on the same line.

Here’s my current code:
result = s.match(/<!–(.*?)–>)

How do I get the regexp to scan for the pattern beyond newlines?

Best regards,

Add an “m” for multiline after the missing closing delimiter “/” for the
regexp

Try this one:
result = s.match(/<!–([\s\S]*?)–>/)

s=<<HERE

HERE

result = s.match(/<!–(.*?)–>/m)[1]
=> " some \ntext "
