On a daily basis I work with TextPipe, and the word has to get out! This tool is so kewl... I started using it for data mining in combination with Offline Explorer, but TextPipe has way more to offer.
Its saves you so much time changing or ripping files from whatever kind.. just create the filter or use one of the many available, and pick the target.
Even the most complex filters or perl strings are creatable with the addon Easy Pattern Maker!
TextPipe can also dig deep into your database.. and change what ever you want.
In my case in example, I had 300+ productpages locally saved, and in a few minutes I created the perfect filter to get rid of all the HTML tags and extra unwanted info :P TextPipe run through all the files in a couple of seconds to fix it and to add the info and style I created!
