If my xml structure looks like this:
var inputXML:XML =
<books>
<book name="da vinci code" author="dan brown" price="12.22"
quantity="2"/>
<book name="angels and daemons" author="dan brown" price="10.20"
quantity="4"/>
<book name="digital fortress" author="dan brown" price="12.22"
quantity="5"/>
</books>;
I wanted an e4x expression to get the total of price*quantity across
all the books.
The way I am trying to achieve this is:
define a function:
public function addToTotal(totalObj:Object,
perBookTotal:Number):void
{
totalObj.totalAmt+=perBookTotal;
}
then call the function from e4x expression:
var totalClass = new Object();
totalClass.totalAmt = 0;
inputXML.book.(addToTotal(
totalClass, Number(@price)*Number(@quantity)));
trace(totalClass.totalAmt);
I am in the process of trying this. Is this going to work at all? Or
is there a better way of achieving this.
Thanks in advance for all the help.
