InfoPath - Navigating Through Each Record Of Repeating Table?

I have an Infopath form that retrieves data from a datasource, then populates a repeating table with a dynamic number of rows depending on employid. Once the data is populated, a "user" can enter numbers, times, etc. That part works fine. Now, what I would like to do is submit the data to a sql database. I just can't figure out how to navigate through each record of the repeating table. I have tried the following code, but have been unsuccessful. I can not get the XpathNodeIterator to work on the secondary datasource.

Dim domNav As XPathNavigator = Me.DataSources("getEmpHourlyPaycodes").CreateNavigator()
Dim rows As XPathNodeIterator = domNav.Select("/my:myFields/my:ReturnedData")
While rows.MoveNext()
Dim field1 As String = rows.Current.SelectSingleNode( _
"my:descriptn", NamespaceManager).Value
' Submit code will go here.
End While
