- Have divs with class .highlight
- Have img tags
- Do not have divs with class .main

Analogous to [this answer on another question](http://stackoverflow.com/a/7549515/1470607), you can use [PhantomJS](http://phantomjs.org/) to open the files and then check if they fulfill all the requirements you have. You can then, for example, return a list of the files that do fulfill your requirements. PhantomJS (headless Webkit) has the advantage that it won't simply die on ill-formed XML (as opposed to some parsers). – Etheryte Jun 05 '14 at 20:29

For simple queries you can use grep (avaliable on *nix platforms usually, can install on Windows as well) which uses regular expressions, but that would only work in one case here. For your image tags:
grep -R <img *.html
Otherwise you would actually need a parser because what you are talking about requires parsing html tags and examining their contents. There are many libraries out there for this- but it's not something built into the command line.
