I have a project in which I get xml posted via a hidden form field (data=<xml></xml>). People are entering names like Bill & Sandy Smith. this is coming over as:
<NameInfo><FamilyName><FamilyNames>David & Karen</FamilyNames><Surname>Adams</Surname></FamilyName></NameInfo>

When I try to load this up in a XmlDocument it blows up.

string xmlData = Request.Form["RequestData"];
dom.LoadXml(xmlData);

results with this:
"This is an unexpected token. The expected token is 'EndElement'. Line 1, position 1022."

I really don't want to go and put some hack in like replacing any & with a + or something like that. But every diferent way I try to load the string blows up.

I can't reproduce the problem, the following code works just fine:

XmlDocument doc = new XmlDocument();
string xml = "<NameInfo><FamilyName><FamilyNames>David &
Karen</FamilyNames><Surname>Adams</Surname></FamilyName></NameInfo>";
doc.LoadXml(xml);
doc.Save(Console.Out);

Debug and inspect what xmlData value really is.
