XML

Hello!
In "My Warehouse" what is the correct xml-structure for transferring the purchase price of the goods?
For example, an order is transmitted as follows:
<Document>
<Id>999Id>
<Number>999Number>
<Date>2015-09-03Date>
<Time>20:53:15Time>
<Currency>rub.Currency> <Currency>1Course
>
< Household Operation>Order Goods Household Operation>
etc.
And what is the structure for updating the product?
