Select part of point text objects matching a regex expression

Hmm, that one is still coming up with 'atf' as 'no such element'

#target illustrator

function test(){

// regex_changeContentsOfWordOrString_RemainFormatting.jsx

// regards pixxxel schubser

var doc = app.activeDocument;

var s = new RegExp("\\d{3}","gi");

var myStyle = doc.characterStyles.getByName("MyStyle");

for ( i = app.activeDocument.textFrames.length; i >=0; i-- ) {

    var atf = activeDocument.textFrames;

    var result, aCon;

    while ( result = s.exec(atf.contents)) {

        try {

            aCon = atf.characters[result.index];

            aCon.length = result[0].length;

            myStyle.applyTo(aCon);

            } catch (e) {};

        }

}

};

test();

Any help is so appreciated! I'm thinking that maybe i'm going about this loop in the wrong way all together..

Wow! I think that might be the ticket. I'm not having luck making it work though. I think it must be that my regex is incorrect. I'm wondering if you could shed any light on what I'm doing wrong.

#target illustrator

function test(){

// regex_changeContentsOfWordOrString_RemainFormatting.jsx

// regards pixxxel schubser

var doc = app.activeDocument;

var s = new RegExp("[0-9]*$","gi");

var myStyle = doc.characterStyles.getByName("MyStyle");

var atf = activeDocument.textFrames[0];

while (result = s.exec(atf.contents)) {

    try {

        aCon = atf.characters[result.index];

        aCon.length = result[0].length;

        myStyle.applyTo(aCon);

        } catch (e) {};

    }

};

test();

assuming

-I have a character Style setup named "MyStyle"

-I have two point text objects:

            "one / 334 / three"

            "first / 563 / third"

-I have the point text objects selected (or un-selected?)

when I run the script it should set "334" and "563" from whatever the style was to 'MyStyle', correct? The script appears to run correctly without any errors, but does not make the character style change. If I don't have 'MyStyle' setup, i get an error reporting that.

Thank you!
