Indesign Buscar/cambiar mayúsculas a small caps y superíndice

Ah well...

I did find the time ^^ (to be tested in real life)

Script also manage the possibility of "Ier siècle".

I kept Harb's feature to run script on parentStory's selection, or over the whole doc if nothing is selected.

// Remplacer les siècles en majuscule par des petites caps et mettre le "e" en exposant.
// by Vinny, Based on "CapstoSmallCaps" script by Harbs.
(function() {
    if (app.documents.length == 0) {
        return
    }
    var doc = app.documents[0];
    // Nom des styles de caractères  
    var SmallCaps_charstyle_name = 'Petites Capitales';
    var Superscript_charstyle_name = 'Exposant';
    //Crée le style de caractère Petites Capitales si n'existe pas déjà
    var SmallCapsCS = doc.characterStyles.itemByName(SmallCaps_charstyle_name);
    if (!SmallCapsCS.isValid) {
        var SmallCapsCS = doc.characterStyles.add();
        SmallCapsCS.name = SmallCaps_charstyle_name;
        SmallCapsCS.capitalization = Capitalization.smallCaps;
    }
    //Crée le style de caractère Exposant si n'existe pas déjà
    var SuperscriptCS = doc.characterStyles.itemByName(Superscript_charstyle_name);
    if (!SuperscriptCS.isValid) {
        var SuperscriptCS = doc.characterStyles.add();
        SuperscriptCS.name = Superscript_charstyle_name;
        SuperscriptCS.position = Position.SUPERSCRIPT;
    }
    try {
        var range = app.selection[0].parentStory
    } catch (err) {
        var range = doc
    }
    app.findGrepPreferences = app.changeGrepPreferences = null;
    app.findGrepPreferences.findWhat = "\\<[IVX]+\\Ker?\\>";
    var finds = range.findGrep();
    for (var i = 0; i < finds.length; i++) {
        finds.appliedCharacterStyle = SuperscriptCS;
    }
    app.findGrepPreferences = app.changeGrepPreferences = null;
    app.findGrepPreferences.findWhat = "\\<[IVX]+(?=er?\\>)";
    var finds = range.findGrep();
    for (var i = 0; i < finds.length; i++) {
        finds.changecase(ChangecaseMode.lowercase);
        finds.appliedCharacterStyle = SmallCapsCS;
    }
    app.findGrepPreferences = app.changeGrepPreferences = null;
