Hi,

I realise this is an incredibly basic question, but after reading the relevant man pages, chapters from Perl books, and hours of experimenting, I still can't work out the answer... I want to write a regex that will search a multi-line string -- starting with '<noframes>' and ending with '</noframes>' -- for hypertext links that do not include either 'netscape.com' or 'microsoft.com' anywhere in the URL portion. I then want to extract this URL using the standard $<integer_here> method. The match should be case-insensitive.

Sample input (value of $page) is:
===

<noframes>

<a HREF="http://www.microsoft.com/browser"> <A href ="http://perlmonks
+.com/" </noframes>

[download]
===
My latest, yet clearly erroneous, attempt is:
===
$page =~m|<noframes>(?:.*?)<a href(?:\s?)=(?:\s?)"(http://(?:.*?)[^net
+scape\.com|^microsoft\.com](?:.*?))"|is;
$url_containing_neither_value = $1;

[download]
===
I would appreciate any help you can provide.

Thank you. :)
