Question

I have an ArrayCollection derived from a httpService call where the XML looks like the following:

<data>
    <label>John</label><height>5.5</height>
    <label>John</label><height>7.2</height>
    <label>John</label><height>3.2</height>
</data>

I know how to use Math.min and Math.max on an array but how would I get the min and max of just the height in this example? Thanks!

Answer 1

I would just use the ArrayCollection‘s Sort method to sort it by height. Then just take the height values from the first and last records in the ArrayCollection.

Update:

I’ll add shaunhusain’s solution since code formatting in comments isn’t the best.

public var minValue:int = int.MAX_VALUE; 
public var maxValue:int = -1; 

for each (var o:Object in myArrayCollection)
{
  if (o.height > maxValue)
    maxValue = o.height;

  if (o.height < minValue)
    minValue = o.height;
}
