Zaloa,
You haven't answered my question as what the problem is. Do these rules
compile?
It seems to me that you have misunderstood how the condition part of the
rules work.
I agree with David that it would help for you to study the manual some
more and to work through some of the tutorials.
Since this is a Drools forum, there are probably not a lot of folks who
understand exactly how JAXP translates the XML into beans. You are more
likely to get help here if you include the relevant portions (get
methods) of the API output by JAXP.

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,

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

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
