hpricot - parse html

[K. R.]

hi @all

I would like to parse html code and remove all tags that starts with
<!-- and end with -->

How can I remove this tags with regex? I used the gsub! function to
manipulate the string.

Thanks for helping...

Try this...

C:\temp>irb
irb(main):001:0> mystring = "xxx<!-- and end with --> yy <!-- another
comment --> zz"
=> "xxx<!-- and end with --> yy <!-- another comment --> zz"
irb(main):002:0> mystring.gsub(/<!--.*?-->/,'')
=> "xxx yy zz"

Regards,
Jim

You should also process the \n, \r char.

So I think the regex should be "<!--(.|\n|\r)*?-->".

Don't forget about the multiline option, it's easy, just stick an 'm'
after the regexp.
