Create a string array of all comments in a html file...

[sophie_newbie]

Hi, I'm wondering how i'd go about extracting a string array of all
comments in a HTML file, HTML comments obviously taking the format
"<!-- Comment text here -->".

I'm fairly stumped on how to do this? Maybe using regular expressions?

Thanks.

You should probably eat beautiful soup at

which helps with this sort of task.

E:\Ruby>irb --prompt xmp
"<!-- Comment

<p>It was a dark and stormy night.
</p><!-- Comment <> -->".scan(/<!--.*?-->/m)
==>["<!-- Comment\nhere -->", "<!-- Comment <> -->"]
