JESS: Jess clp, JessML and Strings with embedded XML

[Nguyen, Son]

Hi

I ran into an issue with String having embedded XML content.
Jess clp and JessML behave differently.

I have a clp function that prints out the String parameter.
I use the Jess XMLPrinter to transform the clp file into JessML.

They yield different results. In the clp case, the string is properly
handled, that is untouched.
Well, at least I think it is. In the JessML case, the string is
'interpreted' and the escaped XML becomes real XML.

Any feedback is greatly appreciated.

Here is the clp:

(deffunction aaa (?string) 
    (printout t "This is what I got" crlf ?string))

(defrule rule1 
        =>
        (aaa "<?xml version=\"1.0\" encoding=\"UTF-8\"?>
        <xmlDoc version=\"1.0\">
                <value name=\"data\">

&lt;Values version=\"2.0\"&gt;
  &lt;value name=\"xml\"&gt;set in cell &lt;/value&gt;
&lt;/Values&gt;

        </value>
    </xmlDoc>
"))

(reset)
(run)



The ouput for the clp run:

<?xml version="1.0" encoding="UTF-8"?>
        <xmlDoc version="1.0">
                <value name="data">

&lt;Values version="2.0"&gt;
  &lt;value name="xml"&gt;set in cell &lt;/value&gt;
&lt;/Values&gt;

        </value>
    </xmlDoc

The output for the JessML run:

<?xml version="1.0" encoding="UTF-8"?>
                <xmlDoc version="1.0">
                        <value name="data">
        
        <Values version="2.0">
          <value name="xml">set in cell </value>
        </Values>
        
                </value>
            </xmlDoc>
