XML string element that contains XML tags within the value text

I want to have a string element with the following contents:

<UmlMessage>"@MainApp -> ControlThread : <font color=red><b>NET_SET_REQ</b>"</UmlMessage>

So the element UmlMessage value will be: "@MainApp -> ControlThread : <font color=red><b>NET_SET_REQ</b>"

I added the quotes, but that did not help. I get a strange error:

XMLSyntaxError: AttValue: " or ' expected, line 25, column 54

I assume it is to do with having XML-like tags in the value. But I want what is between the tags to be parsed as a string literal... is that possible?

Wrap the string content in a CDATA element if it contains "problematic" characters:

<UmlMessage><![CDATA["@MainApp -> ControlThread : <font color=red><b>NET_SET_REQ</b>"]]></UmlMessage>

Option 1, assuming you don't really need the double quotes around the whole message, and you don't mind the contents of UmlMessage being parsed as XML:

<UmlMessage>@MainApp -> ControlThread : <font color="red"><b>NET_SET_REQ</b></font></UmlMessage>

Option 2, as above but with double quotes around message:

<UmlMessage>"@MainApp -> ControlThread : <font color='red'><b>NET_SET_REQ</b></font>"</UmlMessage>

Option 3, if you don't want the contents of UmlMessage to be parsed as XML, regardless of whether you require the surrounding quotes:

<UmlMessage><![CDATA["@MainApp -> ControlThread : <font color=red><b>NET_SET_REQ</b></font>"]]></UmlMessage>

BTW, even though browsers will tolerate missing delimiters around attribute values (color=red), I'd still recommend using them so that your markup is well-formed XML. Similarly, I especially recommend explicitly closing the font element and have done so for you in the above examples.
