Scenario:
I have a ip form thats is link to a sql database table.
My main connection look like this:
(dfs:myFields/dfs:datafields/d:Orders/:orderid)

Order is a Repeating Group.

I try the next statement:
var row = XDocument.DOM.selectSingleNode("//d:Orders");
row.selectSingleNode("orderid").text = 1; (here is the problem)
ip send me error:
XDocument.DOM.selectSingleNode(...)' is null or not is a object

why??

I work with this before and work fine, but now the difference is the repeating group, with "d:", how i can solve this problem?

somebody?

I solve my problem, my solutions was:

use "@" before the name node.
row.selectSingleNode("@orderid").text = 1;

Thanks.

Great! Glad you were able to get it working!
