Örnek: Eşi açık modu kullanarak oluşturma
Satış siparişi bilgileri sağlayan xml oluşturmak istediğinizi varsayalım.Dikkat <SalesPerson> ve <OrderDetail> öğelerdir eşi.Her sipariş sahip <OrderHeader> öğesi, bir <SalesPerson> öğesi bir veya daha fazla <OrderDetail> öğeleri.
<OrderHeader SalesOrderID=... OrderDate=... CustomerID=... >
<SalesPerson SalesPersonID=... />
<OrderDetail SalesOrderID=... LineTotal=... ProductID=... OrderQty=... />
<OrderDetail SalesOrderID=... LineTotal=... ProductID=... OrderQty=.../>
...
</OrderHeader>
<OrderHeader ...</OrderHeader>
Bu xml açık modu aşağıdaki sorgu oluşturur.Sorgu belirtir bir Not Tag değerler için 1 <OrderHeader> öğesi için 2 <SalesPerson> öğesi ve 3 <OrderDetail> öğesi.Çünkü <SalesPerson> ve <OrderDetail> olan eşi, aynı sorguyu belirtir Parent Etiket tanımlama 1 değeri <OrderHeader> öğesi.

SalesOrderID as [OrderHeader!1!SalesOrderID],
OrderDate as [OrderHeader!1!OrderDate],
