Cleaning up text: from ALLCAPS to <em>allcaps</em> - html

Question

I need to clean up some text for html that used ALLCAPS instead of italics. So I'd like to take something that looks like this:
Here is an artificial EXAMPLE of a piece of TEXT that
uses allcaps as a way of EMPHASIZING words.
And convert it into this:
Here is an artificial <em>example</em> of a piece of <em>text</em> that
uses allcaps as a way of <em>emphasizing</em> words.
I'm tagging this with regex and notepad++, but (as you can probably tell) I don't know the first thing about how to use them.

Answer 1

There're no such possibilities with Notepad++ regex engine.
You can run a script that do the job, in Perl for example:
perl -pi.back -e "s#\b([A-Z]+)\b#'<em>'.lc($1).'</em>'/eg" yourfile.html
yourfile.html will be saved in yourfile.html.back

Answer 2

As far as I konw the regex engine of Notepad++ is not advanced enough to do this.
I would advice to use a programming language to accomplish this, in PHP for example you could do this:
echo preg_replace_callback('/([A-Z]{2,})/', create_function('$s', 'return "<em>".strtolower($s[0])."</em>";'), $s);
Be sure to exclude the legitim first capital letter of a single word in the regex.

Answer 3

AFAIK you cannot change casing in the Find\Replace mechanism of Notepad++.
If all you need is the <em> tag insertion you can do the following:
In the Find box type (\s+)([A-Z]+)(\s+), abd in the Replace type \1<em>\2</em>\3.
You can try some of the TextFX tools maybe in the TextFX Characters sub-menu.

Answer 4

Here is how to do this using JavaScript's string replace method:
var capfix = function (x) {
var emout = function (y) {
y = y.charAt(0) + "<em>" + y.toLowerCase() + "</em>" + y.charAt(y.length - 1);
};
return x.replace(/\s[A-Z]\s/g, emout);
};
To execute just call:
capfix(yourData);
This assumes that "yourData" is just a variable that represents your data as a string. If you wanted to use a web tool then "yourData" could represent the value from some input control, as in the following:
var yourData = document.getElementById("myinput").value;
alert(capfix(yourData));
To make that work just put an id attribute on your web tool input such as:
<textarea id="myinput"></textarea>
