for(var i = 0; i < XDocument.DOM.selectNodes("my:myFields/my:group1/my:group2").length; i++)

{

XDocument.UI.Alert(XDocument.DOM.selectSingleNode("my:myFields/my:group1/my:group2[i]/my:pickupReady").text);

}

I can't seem to get this to work.  group2 is a repeating table with a cell containing a checkbox, pickupReady.  I want to cycle through the rows and evaluate whether or not the checkbox is clear. the following works:

XDocument.UI.Alert(XDocument.DOM.selectSingleNode("my:myFields/my:group1/my:group2[1]/my:pickupReady").text);

I can enter any number as long as there is a corresponding row but i don;t want to manually enter the row number, i want it done programmatically using the variable "i".

When I use the variable "i" as I did at the very top infopath errors out and says an object is required.  Why can't I use the variable?  I have also tried the following:

XDocument.UI.Alert(XDocument.DOM.selectSingleNode("my:myFields/my:group1/my:group2["+ i +"]/my:pickupReady").text);

again it isn;t working... anyone have a suggestion?

I am now not 100% but is there a position 0 for repeating tables ? So my best guess would be to try for(var i = 1; i <= XDocument.DOM.selectNodes("my:myFields/my:group1/my:group2").length;i++) and you cannot use [i] you have to use the second syntax you posted [" + i + "].

Does it help ?

Nukkumati is correct. There is no position 0 in XML. Weird, huh?

To avoid these problems, use the preffered method of looping:

var list = XDocument.DOM.selectNodes( "_xpath_to_repeating_structure_" );
var node;
while( ( node = list.nextNode()) != null )
{
    XDocument.UI.Alert( node.text );
}


If you're using C#, you can use the foreach, and it's even a little cleaner.

ah, man. there is always an easy answer.  I shoould have asked the question HOURS ago.  thanks guys, the solution works great.  Now in order to evaluate the specific field in the specific row i changed the code block within the while loop to this:

XDocument.UI.Alert(node.selectSingleNode("my:pickupReady").text);

 and it all works great.
