Re: RV: [rules-users] Checking an xml field

What is the problem you are seeing? Do the rules compile ok? Otaduy del Paso, Zaloa [10/6/2008 12:08 PM] wrote: 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.
