Rails - Feb 2006 - Multiple Characters Negate Using Regexp

Dear experts,
  
  I am trying to build a regular expression to filter out anything  between
<script ... > and </script> tags where I can  specify something
using negate class to exclude more than one character  in sequence.
  
  I tried:
  
 
originalresponse.gsub(/<script([^>]+)>([^<]+)?<\/script>/,'''')
  
  but obviously if the script has the character < before </script> then
my regexp breaks.
  
  I also tried:
 
originalresponse.gsub(/<script([^>]+)>([^<\/script]+)?<\/script>/,'''')
  
  but it doesn''t work
  
  
  Can anyone guide me on how I can specify multiple character negation?
  I will greatly appreciate it.
  
  Is this even possible? How else can I remove everything contained between
<script> tags?
  
  Thanks
  Frank

Is it possible to specify a multiple line regular expression?
  
  Thanks for your assistance.

Can you restate your original problem a bit better?  Are you wanting to 
delete everything between the <script> and </script> tags?

If so, I think this expression should work (famous last words :-)

/(< *script.*?>).*?(<\/ *script *>)/

I tried it like this:

irb(main):001:0> "hello <script>goodbye</script>
there".gsub(/(<
*script.*?>).*?(<\/ *script *>)/,'''')
=> "hello  there"

I recommend /<script([^>]+)>.*?<\/script>/

Adding the ? after the * makes it un-greedy, so it will match the
first following tag, as in the following example.

irb(main):001:0> s = "I have a <script foo> tag > inside <
me
</script> don''cha know </script> :)"
=> "I have a <script foo> tag > inside < me </script>
don''cha know </script> :)"
irb(main):002:0> r = /<script([^>]+)>.*?<\/script>/
=> /<script([^>]+)>.*?<\/script>/
irb(main):003:0> s.gsub(r,'''')
=> "I have a  don''cha know </script> :)"

yes, just put ''m'' after it, e.g.

   %r{<textarea[^>]*?id="markup"[^>]*>([^<]*)}m

or

   /<textarea[^>]*?id="markup"[^>]*>([^<]*)/m
