Parsing XML with .ReadXml

Skip the ReadXml method and add the columns and rows to the DataTable yourself then. Something like this:

string strXML = "<root><trlFlags><trlFstmp /></trlFlags><trlFlags><trlPLU /></trlFlags></root>";

            //check if the xml is properly parsed
            XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.LoadXml(strXML);

            DataSet ds = new DataSet();
            DataTable dt = new DataTable();
            ds.Tables.Add(dt);
            XmlNodeList trlFlags = xmlDoc.SelectNodes("//trlFlags");
            foreach (XmlNode node in trlFlags)
            {
                DataRow dr = dt.NewRow();
                foreach (XmlNode childNode in node)
                {
                    var existingColumn = dt.Columns.Cast<DataColumn>().FirstOrDefault(c => c.ColumnName.Equals(childNode.Name));
                    if (existingColumn == null)
                    {
                        dt.Columns.Add(new DataColumn(childNode.Name));
                        
                    }
                    dr[childNode.Name] = "1";
                }
                dt.Rows.Add(dr);
            }

Hope that helps.
