You need to encode/escape the characters. You can do it manually if you
know all of the rules, but I wrote a little utility for myself that I
know will do it right. I guess I should post the full app at some point,
but the relevant method is:

public string Encode(string input)
{
StringBuilder output = new StringBuilder();
using (StringWriter stringWriter = new StringWriter(output,
CultureInfo.InvariantCulture))
{

XmlTextWriter xmlWriter = new XmlTextWriter(stringWriter);
xmlWriter.WriteStartElement("element");
xmlWriter.WriteAttributeString("attribute", input);
xmlWriter.WriteEndElement();
xmlWriter.Close();
}
return output.ToString();
}
Just create a simple WinForms app with a textbox to past a value into, a
button that runs the Encode method, and then a textbox for the output
(not label - you want to be able to select the output for copy/paste).
