I have a .Net service application that uses the System.Xml.XmlNode class to 
hold xml nodes read from a configuration file.  Each xml node object is then 
stored in an Array List.  I iterate over the Array List to get the values of 
a specific attribute in each node.  
All this works fine in my debug environment (.Net 2003, Framework v.1.1, 
WinXP,SP1) with no problems.  But when the application is deployed on a 
(Win2K Server, .Net Framework v.1.0 and v.1.1 installed) I am receiving an 
exception that says my XmlNode object is not set to an instance of an object. 
 I placed test code in various parts of the app trying to debug and always 
get the same result.  Below is a sample code, I am performing.

foreach (Object oEvent in alExcludeEvents)
{
  System.Xml.XmlNode currentEvent = (XmlNode) oEvent;
  // Fails when trying to get named item. object not set to an instance of 
an object.
  string strCurrPattern = 
currentEvent.Attributes.GetNamedItem("pattern").Value;
  // do something with the attribute value.
}

I am stumped.
Thanks in advance for any help.
