Hi there,

I am using the following code to creata a xml node with 5 attributes but I discover the last attribute is always missing. Can anyone help me to find out what is the problem? 

================================================================================= 

   XmlDocument doc = new XmlDocument();
   XmlNode node = doc.CreateElement("WORKER_ALLOCATION_OpenEpisode", NamespaceManager.LookupNamespace("d"));
   XmlAttribute attr;

   attr = doc.CreateAttribute("OpenEpisodeID");   
   node.Attributes.Append(attr);
   
   attr = doc.CreateAttribute("WorkerAllocationID");
   node.Attributes.Append(attr);
   
   attr = doc.CreateAttribute("EpisodeNumber");
   attr.Value = episodeNumber;
   node.Attributes.Append(attr);

   attr = doc.CreateAttribute("T2Team");
   attr.Value = T2Team;
   node.Attributes.Append(attr);

   doc.CreateAttribute("PrimaryClinician");
   attr.Value = primaryClinician;
   node.Attributes.Append(attr);   
   
   doc.AppendChild(node);

====================================================

The xml content of variable doc is as follows and the last attribute, named "PrimaryClinician", is missing.

 <WORKER_ALLOCATION_OpenEpisode OpenEpisodeID="" WorkerAllocationID="" EpisodeNumber="E001" T2Team="Don Murrphys" xmlns="http://schemas.microsoft.com/office/infopath/2003/ado/dataFields" />  

You're missing "attr = " in the fourth line from the end.
