I have a string which contains XML, I just want to parse it into Xelement, but it has an ampersand. I still have a problem parseing it with HtmlDecode. Any suggestions? 

string test = " <MyXML><SubXML><XmlEntry Element="test" value="wow&" /></SubXML></MyXML>"; 

XElement.Parse(HttpUtility.HtmlDecode(test));

I also added these methods to replace those characters, but I am still getting XMLException.

string encodedXml = test.Replace("&", "&amp;").Replace("<", "&lt;").Replace(">", "&gt;").Replace("\"", "&quot;").Replace("'", "&apos;");
XElement myXML = XElement.Parse(encodedXml);

t or Even tried it with this:

string newContent=  SecurityElement.Escape(test);
XElement myXML = XElement.Parse(newContent);
xelement xml c#

This is the simplest and best approach. Works with all characters and allows to parse XML for any web service call i.e. SharePoint ASMX.

public string XmlEscape(string unescaped)
        {
            XmlDocument doc = new XmlDocument();
            var node = doc.CreateElement("root");
            node.InnerText = unescaped;
            return node.InnerXml;
        }

Filip's answer is on the right track, but you can hijack the System.Xml.XmlDocument class to do this for you without an entire new utility function.

XmlDocument doc = new XmlDocument();
string xmlEscapedString = (doc.CreateTextNode("Unescaped '&' containing string that would have broken your xml")).OuterXml;

Perhaps consider writing your own XMLDocumentScanner. That's what NekoHTML is doing to have the ability to ignore ampersands not used as entity references.
