VB.NET and probably the other managed code languages uses a new syntax for specifying nodes and traversing XML in a form. I don't claim to have a firm grasp on this, I only know what works. Let's say you've got a field in your form whose value you set via rules or defaults, like a datetime field. Below is how you would specify a function to get into your main datasource, get to the value, set it to a variable and then do something with it. This may be basic info for some of you, but it's a different syntax to me and is worth noting here.
Private Function currentDateTime() As String
Dim mainDomNavigator As XPathNavigator = MainDataSource.CreateNavigator()
Dim todayNavigator As XPathNavigator = mainDomNavigator.SelectSingleNode("/dfs:myFields/my:TodaysDate", NamespaceManager)
Return todayNavigator.Value
End Function
