RV: [rules-users] Checking an xml field

[Otaduy del Paso, Zaloa]

Does anybody know the answer to my question? I'm not able to solve this
issue and don't find any clarifying tutorial either....

 

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
