I've a repeating table inside another repeating table. I can loop through the outer repeating table and read the fields, but having dificulty to loop through the inner repeating table.

Very much appreciate your help. 

myFields
  group1
    group2
       field1
       field2
       group3
         group4
            field3
            field4 

Dim itr1 As XPathNodeIterator = nav1.Select("/my:myFields/my:group1/my:group2", NamespaceManager)

While itr1.MoveNext()

  ?? How can I loop through gorup4 here and read the fields ??

Next

Dim itr2 As XPathNodeIterator = itr1.Current.Select("my:group3/my:group4", NamespaceManager)

While itr2.MoveNext()

 ' do stuff

Next

Yes it worked. Thank you so much for the help.
