I am having difficulty parsing a unicode (UTF-16) XML file that has
been generated by a 3rd party piece of software.

I ideally would like to use XmlDocument though would settle with using
XmlTextReader

Thanks

Well what difficulties exactly do you have? The .NET framework supports
UTF-16 and its Xml parsers certain do too. It sounds more like the file
is not properly UTF-16 encoded.

How does the XML look like, how does the parsing code look like and
what error do you get ?

The XML file looks like this (in notepad) <?xml version="1.0"
encoding="utf-16"?><form Id="1111"></form> in VS 2008 looks like 㼼浸â¬æ•¶ç²æ½©
㵮ㄢ〮•湥潣楤æ®âˆ½ç‘µâµ¦ã˜±ã¼¢ã°¾æ½¦æµ²ä¤ ãµ¤ã„¢ã„±âˆ±ã°¾æ˜¯ç‰¯ã¹­

I have tried parsing like

string filePath = "form.xml";

XmlDocument doc = new XmlDocument();

doc.Load(filePath);
XmlNode formNode = doc.FirstChild;

Error I get is There is no Unicode byte order mark. Cannot switch to
Unicode.

I have also tried

StreamReader reader = new StreamReader(filePath, Encoding.Unicode,
true);

XmlTextReader textReader = new XmlTextReader(reader);

textReader.Read();

Error I get now is Data at the root level is invalid. Line 1, position
1.

Any ideas? Thanks

Have you tried the obvious - putting a BOM first in the file ?

This works with a little-endian UTF-16 file with no BOM:

StreamReader reader = new StreamReader("form-le.xml",Encoding.Unicode);
XmlDocument doc = new XmlDocument();
doc.Load(reader);
XmlNode formNode = doc.FirstChild;
