find and replace links in a large text file

is there a utility, or is it possible with notepad++ or any other of the popular code editors to do a search and replace with wildcards?

eg. say you have a large text file, that is scattered with a bunch of <a href... type of links, but they are all different as far as text and url's, I would like to use a * wildcard to be able to search for all occurences of any type of link and replace it with something else

any ideas?

interesting, I need it to do some regexp matching though, the old url's are all different, and I want to match them all with one command

wildcard to match any type of link? Sure!

Code:

/a[\s]+[^>]*?href[\s]?=[\s\"\']+(.*?)[\"\']+.*?>([^<]+|.*?)?<\/a>/i

Enjoy.

download textpad, it works great.

press F8, then use .*. as the wild card.

The above is Perl Regex, not "universal" regex.

I just use TextPad for that kind of shit when on Windows It usually takes normal, or semi-perl regex just fine. Sorry, never used NP++.

found the answer:

Code:

<a href="[^"]+">[^<]+</a>

thanks for the help, it was interesting, maybe this thread will help someone else too
