InfoPath Dev

Hello,

 I have a C# program that loops through all of the forms in my form library and injects an XML node where it's missing.  The problem is that once the xml is saved, the first few tags that are in every one of my IP forms are getting stripped off.  Specifically, these tags are being removed:

<?xml version="1.0"?>
<?mso-infoPathSolution name="urn:schemas-microsoft-com:office:infopath:Contractor-DB-Form:-myXSD-2009-09-10T18-19-55" solutionVersion="1.0.1.1081" productVersion="12.0.0.0" PIVersion="1.0.0.0" href="http://echouat.rbs.us/npe/FormServerTemplates/Contractor_DB_Form.xsn"?>
<?mso-application progid="InfoPath.Document" versionProgid="InfoPath.Document.2"?>
<?mso-infoPath-file-attachment-present?>

 My code is as follows:

        private static SPListItem InsertXmlNode(SPListItem infoPathForm, string nodeToUpdateStr, string nodeToInsertStr,
            string nodeInnerXmlStr, string firstNode)
        {
            //load form into xml document
            byte[] fileBytes = infoPathForm.File.OpenBinary();
            MemoryStream itemStream = new MemoryStream(fileBytes);
            //Stream itemStream = infoPathForm.File.OpenBinary();
            XmlDocument xmlDoc = new XmlDocument();
            XmlNamespaceManager xmlNameSpaceMgr = new XmlNamespaceManager(xmlDoc.NameTable);
            xmlNameSpaceMgr.AddNamespace("my", "http://schemas.microsoft.com/office/infopath/2003/myXSD/2009-09-10T18:19:55");

            xmlDoc.Load(itemStream);
            itemStream.Close();

            //inject xml
            XmlNode nodeToUpdate = xmlDoc.SelectSingleNode(firstNode + nodeToUpdateStr, xmlNameSpaceMgr);

            //only insert if doesn't already exist
            if (xmlDoc.SelectSingleNode(firstNode + nodeToUpdateStr + "/" + nodeToInsertStr, xmlNameSpaceMgr) == null)
            {
                updateCounter++;

                XmlNode nodeToInsert = xmlDoc.CreateNode(XmlNodeType.Element, nodeToInsertStr, "http://schemas.microsoft.com/office/infopath/2003/myXSD/2009-09-10T18:19:55");
                nodeToInsert.InnerText = nodeInnerXmlStr;
                nodeToUpdate.AppendChild(nodeToInsert);

                //get binary data for updated xml
                byte[] newXmlData = Encoding.UTF8.GetBytes(xmlDoc.DocumentElement.OuterXml);
                MemoryStream newMemStream = new MemoryStream(newXmlData);

                //write updated binary data to the form
                infoPathForm.File.SaveBinary(newMemStream);

                newMemStream.Close();

                infoPathForm.File.Update();
            }

            return infoPathForm;
        }

I'm not having a problem with the parameters being passed in.  The SPListItem is coming from my forms library.  The other parameters are:

nodeToUpdateStr = "/my:ConfirmationControls"
nodeToInsertStr = "my:DisableAccessSent"
nodeInnerXmlStr = "FALSE"
firstNode = "/my:Contractor_Setup"

 PLEASE HELP!!  I have no idea why these tags are being stripped off.  Once they're stripped, the form can no longer be opened in InfoPath.

 Thanks!

byte[] newXmlData = Encoding.UTF8.GetBytes(xmlDoc.DocumentElement.OuterXml);
               

Use xmlDoc.InnerXml instead.  That should solve the problem.
