Regular Expressions in AS3

Hi

I want to do an If. Example:

var fileName:String = “téste.xml”;

if(???){
trace(“file name as invalid characters, please replace”);
}else{
trace(“do iT”)
};

I need to know how I do this with regular expressions. Instead of writing 100 else if ofr each character á é í í ú ó #$%&/ that can’t be in a file name!

I hope someone can help me!

Thanks
