Target sequences of 2 and more capital letters - css

Question

I'm a graphic designer in a magazine and we'd like our website to be closer to our printed issues.
In the magazine, we use small caps for strings of more than 2 capital letters in a row.
I know it is possible to use true small caps with an OpenType font. I also know that you kan target 1st lines or 1st letters with CSS
So my question is:
Would it be possible to target/detect strings of capitals letter within a text, and apply automatically the font-variant property to it (without having to manually apply styles or classes).
here's an example

Answer 1

If you mean like this, sure! The regular expression could be improved though, as it only matches words, not sequences of words, but regex is still alienspeak to me, so this is the best I can do:
[].forEach.call(document.querySelectorAll(".smallcapsify"), function(content) {
var parsed = content.innerHTML.replace(/[A-Z]{2,}/g, '<span class="small-caps">$&</span>');
content.innerHTML = parsed;
});
#import url(http://fonts.googleapis.com/css?family=Merriweather);
span.small-caps {
font-variant: small-caps;
text-transform: lowercase;
}
/* Styles to make it look nicer */
body {
font-size: 2em;
font-family: Merriweather, serif;
text-rendering: optimizeLegibility;
/* Enable common and discretionary ligatures, according to http://blog.fontdeck.com/post/15777165734/opentype-1 and http://caniuse.com/#search=font-feature-settings */
-webkit-font-feature-settings: "liga", "dlig";
font-feature-settings: "liga", "dlig";
}
<div class="smallcapsify">
This is SOME TEXT. Here is some MORE text.
</div>
