c# Registry to XML Invalid character issue

[Vulpes]

I have a problem when trying to create an XML file from registry. On my laptop(W7 64b) it is working fine, the xml file is generated but on another computer (Xp 32b) an exception is thrown : System.ArgumentException '.', hexadecimal values 0x00, is an invalid character. I have read few useful things about it but I don't know how to solve in this case, here is the code :\[code\] try { string regPath = "SOFTWARE\\IPS"; XElement xRegRoot = new XElement("Root", new XAttribute("Registry", regPath)); ReadRegistry(regPath, xRegRoot); string xmlStringReg = xRegRoot.ToString(); XmlDocument docR = new XmlDocument(); docR.LoadXml(xmlStringReg); docR.Save(AppDomain.CurrentDomain.BaseDirectory + "\\_RegistryList.xml"); } catch (System.Exception ex) { Console.WriteLine(ex.ToString()); LogToFile(ex.ToString()); } private static void ReadRegistry(string keyPath, XElement xRegRoot) { string[] subKeys=null; RegistryKey HKLM = Registry.LocalMachine; RegistryKey RegKey = HKLM.OpenSubKey(keyPath); try { subKeys = RegKey.GetSubKeyNames(); foreach (string subKey in subKeys) { string fullPath = keyPath + "\\" + subKey; Console.WriteLine("\r\nKey Name | " + fullPath); LogToFile("Key Name | " + fullPath); XElement xregkey = new XElement("RegKeyName", new XAttribute("FullName", fullPath), new XAttribute("Name", subKey)); xRegRoot.Add(xregkey); ReadRegistry(fullPath, xRegRoot); } string[] subVals = RegKey.GetValueNames(); foreach (string val in subVals) { string keyName = val; string keyType = RegKey.GetValueKind(val).ToString(); string keyValue = http://stackoverflow.com/questions/11504342/RegKey.GetValue(val).ToString(); Console.WriteLine("Key Value | " + keyType + " | " + keyName + " | " + keyValue); LogToFile("Key " + keyType + " | " + keyName + " | " + keyValue); XElement xregvalue = http://stackoverflow.com/questions/11504342/new XElement("RegKeyValue", new XAttribute("keyType", keyType), new XAttribute("keyName", keyName), new XAttribute("keyValue", keyValue)); xRegRoot.Add(xregvalue); } } catch (System.Exception ex) { Console.WriteLine(ex.ToString()); LogToFile(ex.ToString()); } }\[/code\]Thanks in advance.
