Hey guys, I just wanted to share this:  
I wondered how to create arrays for categories automatically from my blog (wordpress) rss feed and it was quite easy thanks to the filter array method.

here’s the code:

```auto

private function createItems():void {
            for each (var cat:XML in _items.category) {
                if (_categories.length>0) {
                    if (_categories.filter(checkThis)==false) {
                        _categories.push(cat);
                    }
                } else {
                    _categories.push(cat);
                }
            }
            function checkThis(element:*, index:int, arr:Array):Boolean {
                if (element.text()==cat.text()) {
                    return true;
                } else {
                    return false;
                }
            }
            trace("categories are:"+_categories);
        }

```

\_items is an XMLList created by XML…items method

don’t know if it was already posted (maybe in the AS3 tip of the day) if so i apologize 🙂
