<countires>
   <ctnry countryCode='0' label='Select Country' />
   <ctnry countryCode='CAN' label='Canada' />
   <ctnry countryCode='USA' label='United States' />
   <ctnry countryCode='UK' label='United Kingdom' />
   <ctnry countryCode='OTH' label='Other' />
</countires>

    lstcountry.selectedItem = findCountry('CAD');
}  
public function findCountry( countryCode:String):Object
{
    for each( var c:Object in sercountry.lastResult.countires.ctnry)
    {
        if( c.@countryCode == countryCode)
            return c;
    }
    return null;
}
