Re: JESS: making str-cat correctly interpret \" signs

Hi all,

I'm trying to retract a fact via the retract-string method.  I need to use the str-cat method to assemble my fact.  The problem is that the slot values of my fact have " " (double quotations) around them.  str-cat is not detecting that my \" should be interpreted as a " only.

How do I make str-cat concatenate a string which already has "" marks in it, so that it doesn't include the extra \ sign?  See the example below if this is way too confusing to understand. 

Yes, i am importing a .owl file developed in protege.

(retract-string (str-cat
    "(triple
    (predicate \"http://www.semanticweb.org/ontologies/ImageEditor.owl#Pickable\")
    (subject \" " ?tool "\")  <----------- notice the 2 \" on this line
    (object \"false\"))"
                     )
)

The fact in the working set looks like this:
(triple
    (predicate "http://www.semanticweb.org/ontologies/ImageEditor.owl#Pickable")
    (subject "myTool")   <---------  This is how it should look.  No \" should be there.
    (object "false")
)


Thanks,
Chirag
