Regexps and HTML comments

ruby-talk
1

I have troubles with the regexp to get HTML comments ("<!-- some text -->") 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,

Jari Willimasson

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

s=<<HERE
<!-- some
text -->
HERE

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

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