 Hi,

I have a repeating section . There will be two instances for contact and address . I want to set the value dynamically through code based on  a drop down selection.I don't know how to get each instance .The form is basedo an XML Schema.

Here is what the actual XML Should look like :

                    <Contact label="Attn:" linenumber="1">John Smith</Contact>
                    <Contact label="Room:" linenumber="2">640</Contact>

                    <AddressLine linenumber="1">1968 Northeast</AddressLine>
                    <AddressLine linenumber="2">5th Avenue</AddressLine>

here is the part of the code, 

but  as you can see it won't work, Please help.

                   Dim root As XPathNavigator = MainDataSource.CreateNavigator()

                    root.SelectSingleNode("/PurchaseRequisitionMessage/PurchaseRequisition/RequisitionHeader/ShipTo/Address/Contact/@label", NamespaceManager).SetValue("Attn:")
                    root.SelectSingleNode("/PurchaseRequisitionMessage/PurchaseRequisition/RequisitionHeader/ShipTo/Address/Contact/@linenumber", NamespaceManager).SetValue("1")
                    root.SelectSingleNode("/PurchaseRequisitionMessage/PurchaseRequisition/RequisitionHeader/ShipTo/Address/Contact", NamespaceManager).SetValue("Kim Linnet")
                    root.SelectSingleNode("/PurchaseRequisitionMessage/PurchaseRequisition/RequisitionHeader/ShipTo/Address/Contact/@label", NamespaceManager).SetValue("Room:")
                    root.SelectSingleNode("/PurchaseRequisitionMessage/PurchaseRequisition/RequisitionHeader/ShipTo/Address/Contact/@linenumber", NamespaceManager).SetValue("2")
                    root.SelectSingleNode("/PurchaseRequisitionMessage/PurchaseRequisition/RequisitionHeader/ShipTo/Address/Contact", NamespaceManager).SetValue("640")

 Thanks

Hi - for your code, look into XPathNodeIterator. You can also do this with qRules, if you'd rather not write code, or this blog post may help you do this without code.
