Hi,
I have tried
OASISTSO10($e: EVENT)
EVENT($g: $e.GEO[0])
OASISTSO10($e.GEO[0].POSITION.LOCID matches
"40.*")
It makes sense to me, since
OASISTSO10($e: EVENT)
OASISTSO10($e.GEO[0].POSITION.LOCID matches
"40.*")
Is working and what I want to check is the field GEO from $e. The
issue is that doing what you suggested (the first code lines) I get
the following error:
org.drools.rule.InvalidRulePackage: Unable to create Field Extractor
for '$e.GEO[0]' : [Rule name=DistribuirPorProvincia2,
agendaGroup=MAIN, salience=2, no-loop=false]
_org.drools.RuntimeDroolsException_:
_org.drools.RuntimeDroolsException_:
_org.drools.RuntimeDroolsException_: Field/method '$e' not found for
class 'es.indra.simge.businessrules.jaxb.tso.EVENT'
at org.drools.rule.Package.checkValidity(_Package.java:424_)
I have also tried Scott's suggestion:
OASISTSO10($e: EVENT)
eval($e.GEO[0].POSITION.LOCID.equals("40005"))
but I also get the compilation error:
org.drools.rule.InvalidRulePackage: Rule Compilation error : [Rule
name=DistribuirPorProvincia2, agendaGroup=MAIN, salience=2, no-loop=false]
es/indra/simge/businessrules/jaxb/tso/Rule_DistribuirPorProvincia2_0.java
(9:441) : $e.GEO cannot be resolved or is not a field
at org.drools.rule.Package.checkValidity(_Package.java:424_)
I'm pretty confused because sometimes the $e is recognized as an
event, the rules I already have work, but in other cases the
$e./FIELD/ returns a compilation error.

Might be worth trying
OASISTSO10($e: EVENT)
EVENT($g: $e.GEO[0])
OASISTSO10($e.GEO[0].POSITION.LOCID matches
"40.*")

Hi David,
Thanks for your helpful response. The problem was that the element GEO
can appear 0 or many times so what I needed to write was this
when
OASISTSO10($e: EVENT)
OASISTSO10($e.*GEO[0].*POSITION.LOCID == "40005")
Then
Action
instead of
when
OASISTSO10($e: EVENT)
OASISTSO10($e.GEO.POSITION.LOCID == "40005")
Then
Action
Now I'm facing another problem. I need to check if the element GEO
exists before checking the POSITION, otherwise it throws an outofbound
exception.
I tried with:
when
OASISTSO10($e: EVENT)
EVENT($g: GEO)
OASISTSO10($e.GEO[0].POSITION.LOCID matches
"40.*")
But it doesn't work. Any hints on this?
Thanks in advance,
*Zaloa Otaduy del Paso*

Read the manual man. Your rules don't make any sense

What is the problem you are seeing? Do the rules compile ok?

Hi,
I'm new in drools and I'm having some problems accessing an xml field.
I'm using drools with jaxb to treat xml files that follow an specific
xsd. I have the following xml (this is just a piece of the xml):
<OASIS_TSO_1_0>
<EVENT>
<EVENT_ID>EVENT_ID_03/10/2008 10:22:36</EVENT_ID>
<NODE_ID>00</NODE_ID>
<OTHER_EVENT_ID>Incidente UME</OTHER_EVENT_ID>
<EVENT_TYPE>POL</EVENT_TYPE>
<SOURCE>HUMDED</SOURCE>
<SEVERITY>EXTREM</SEVERITY>
<CERTAINTY>88</CERTAINTY>
<DECL_DATIME>2008-10-03T10:20:47.0000000+02:00</DECL_DATIME>
<GEO>
<DESCRIPTION/>
<POSITION>
<LOC_ID>14021</LOC_ID>
<COORD>
<LAT>37.9811636567434</LAT>
<LON>-4.85417587343286</LON>
<HEIGHT>0</HEIGHT>
</COORD>
</POSITION>
</GEO>
</EVENT>
</OASIS_TSO_1_0>
I already have a couple of rules working, but they are simple rules,
like this one:
rule "Rule1"
salience 10
when
OASISTSO10($e: EVENT)
OASISTSO10($e.SEVERITY == "EXTREM") or OASISTSO10($e.SEVERITY == "SEVERE")
then
action
The problem appears when I have to check the LOC_ID field and I don't
know how to access to it. I have tried several things but none of them
work
1.
when
OASISTSO10($e: EVENT)
OASISTSO10($e.GEO.POSITION.LOCID == "40005")
then
2.
when
OASISTSO10($e: EVENT)
OASISTSO10($g: $e.GEO)
OASISTSO10($p: $g.POSITION)
OASISTSO10($p.LOCID == "40005")
Then
I have also tried with ($e.GEO.POSITION.DESCRIPTION, just in case the
"_" character was the problem. But the same results... I have searched
also for examples with xmls but I haven't had luck.
Any help would be appreciated. Thanks in advance,
Zaloa
