How is data updated ?

Aug 14, 2009 at 1:00 AM

Taking the sample XML & schema  I have

var os = Batch.Load("../../xmlfile1.xml");   // get a value with a variable.

SomeItem =
(
from purchaseOrder in os.PurchaseOrder
from item in purchaseOrder.Item
where item.Quantity == qty
Select item.Price).First();
double dd = SomeItem;

// but how do update this value ?  37 to say 999 ?

Thanks !
