It is not clear how you want to use the
XML?
If the XML represents Facts then you could use a worker
Fact and "FROM" to deserialise them and make them available to WM. For
example:-
rule "get some XML facts"
when
$w : Worker()
Cheese( ) from
$w.getCheesesFromXML();
then
//Do something with cheese
end
Obviously the XML need not be true serialised objects (in a
JAXB sense) but simply the properties that "getCheeseFromXML"
rehydrates.
Drools is not exposing any of the XML libraries; they are
merely used by your code. The above would be (partially) equivalent
to:-
Worker w = new Worker();
List<Cheese> cheeses
= w.getCheesesFromXML();
for(Cheese c : cheeses) {
wm.insert(c);
}
rule "Cheese pre-loaded"
when
Cheese( )
then
//Do something with cheese
end
Partially equivalent as you could retract Cheese( ) in the second way
which would affect truth maintenance whereas the first way would (I believe)
not.
With
kind regards,

Hi
All,
How can we read and parse a XML file using drools ?
Does Drools
support the SAX or DOM parsing .
