Question

So I’m getting data from a 3rd party in the form of an XML String.

I want to then do the following

messageString = Encoding.ASCII.GetString(messageBeingSent);
messageString = messageString.Trim();

XDocument xmlDoc = XDocument.Parse(messageString);

However, it errors out and gives me the exception
hexadecimal value 0x00 is an invalid character. Line 1, Position x where X is the last character in the string.

This appears to me that a null terminator is being sent along with the string and then the XDocument flips out because of the null terminator.

What’s the solution to this?

Answer 1

null character is not valid in XML.

You can pass characters you want to trim:

 messageString.Trim(' ', '\0', ....);
