leave a for each loop

I want to leave the for each loop as soon as the boolean is set to true.

for each (xmlEvent in arEvents)
{
    var xmlEvent:XMLList = XMLList(event);
    if(xmlEvent.id == artistEvent.id)
    {
        boolExists = true;
    }
}

I've tried break and such, but this all doesn't work.

Why not use the some() method? It'll handle all that for you.

boolExists = arEvents.some(
  function (xmlEvent:*, index:int, arr:Array):Boolean {
    return xmlEvent.id == artistEvent.id;
  });

Note: The anonymous function is used only for brevity.

For clarity, the some() method only iterates over the array until the first item that returns true is reached, at which point iteration is terminated and the result (true) is returned.

Use break operator

for each (xmlEvent in arEvents)
{
    var xmlEvent:XMLList = XMLList(event);
    if(xmlEvent.id == artistEvent.id)
    {
        boolExists = true;
        break;
    }
}
