Question

I need to find all hash tags in this text using ActionScript 3 (AS3):

Lorem ipsum dolor #sit_amet, consetetur
sadipscing, sed #diam-nonumy
eirmod tempor #invidunt ut labore #et

What’s a good method to do this?
Thanks
Frank

Answer 1

// your data:
var data:String = "Lorem ipsum dolor #sit_amet, consetetur sadipscing, sed #diam-nonumy eirmod tempor #invidunt ut labore #et";

// this regular expression will match most "normal" characters, add more as needed
// it will stop at the first whitespace or linebreak it hits
var regex:RegExp = /(\#[a-zA-Z0-9_%-]*)/g;

// this object will be used to store our results
var result:Object;

// now, we run the regex until it returns null, 
// that means there's nothing more that matches
while (result = regex.exec(data)) {
    // since we're not using groups or anything, all we want is the 0 in the object
    trace(result[0]);
}

This will trace:

#sit_amet
#diam-nonumy
#invidunt
#et
