Imacros Searching and saving

I am new to imacros. Could anyone point me in the right direction on this -

1. Load a URL
2. search the text for a certain word
3. if the word is found then save the URL to a file (text, csv etc)

I understand that you might not want to give me the answer, but just knowing whether or not it can be done would be a great help.

you should explain more detail so we can help you
