Code editor to find in files using CSS selectors / Emmet abbreviations?

Question

Which code editor or IDE allows me to find a CSS selector or Emmet abbreviation in files of my project?

For example, I type .parent .child in the find box and I should get files containg both:

<div class="parent">
    <div class="child">
    </div>
</div>

and

.parent {
    .child {
    }
}

Element Finder is an app for recursively searching through a directory and finding HTML files which contain elements matching a given CSS selector. There is also a Sublime Text plugin.
