           Summary: Modifying XML dom while iterating over it using
                    foreach displays different behavior to .NET

Test code Showing different behaviour modifying dom while looping over it with
foreach

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.8)
Gecko/2009032711 Ubuntu/8.04 (hardy) Firefox/3.0.8

Attached code sample showing problem.

basically for some XML this works in .NET:

foreach (XmlNode includeNode in doc.SelectNodes("//mynode"))
{
 XmlNode parentNode = includeNode.ParentNode;
 parentNode.AppendChild(newNode);
}

I acknowledge this code is horrible, but given it differs from .NET behavior, I
believe its a bug.


Reproducible: Always

Steps to Reproduce:
1. Compile and run attached test code
2.
3.
Actual Results:  
Infinite loop.

Expected Results:  
blah/drinks1
hello world
New List
blah/drinks1
blah/drinks12
hello world
hello world2
