Hi,
I have the following problem:
In my knowledge base, there are facts like
(deftemplate Tag
(slot DocumentName)
(slot ElementID)
(slot TagName)
(slot ParentID)
(slot Text)
(slot Element))
(deffacts tagdata
(Tag
(DocumentName file:///C:/Jess60/service)
(ElementID 2)
(TagName name)
(ParentID 0)
(Text learning)
(Element <External-Address:org.apache.xerces.dom.DeferredElementNSImpl>))
...and some more of those...
I want to get from a Java program the fact-id of the fact, where the parentID is 0.
I use the following rule:
rete.executeCommand("(defrule getFactIDofRootElement"+
"(Tag (ParentID 0))"+
"=>"+
"(?factID <- (Tag (ParentID 0))))");
If I use the return value, the value is true.
How can I get the fact-id and the fact itself in Java?
I cant use assert, because the Jessfacts are already in the knowledge base.
Thanks a lot for any hint!!!
Vincent
