Question

I have the following XML variable:

public var Country:XML=new XML(
    <countries>
         <country code="US" iso="840" label="United States" />
         <country code="CA" iso="124" label="Canada" />
         <country code="GB" iso="826" label="United Kingdom" />
         ...
    </countries>);

How would I loop through the list to find the index number corresponding to the value stored in String variable myCountry? For example, if

var myCountry:String = "Canada";

How to create a loop that returns an index value of 1, meaning Canada is the 2nd element in the XML list?

Or, maybe looping isn’t necessary if the index value of 1 can be returned some other way. I tried:

var desiredIndex:int = Country.country.(@label==myCountry)

but it gives the error No such variable: @label.

Answer 1

Something like this should do what you want:

var index:int = 0;
for each (var country:XML in Country.country)
{
    if (country.@label == myCountry)
        break;

    index++;
}

(the Country variable should be named countries or something similar… conventionally capitalised names are used for classes only)

I hope this helps
