Scott,
The rules I have now,
compile. The generated jaxb classes I have regarding to what I’m trying
to do are:
EVENT.java
public
class EVENT {
@XmlElement(name = "EVENT_ID", required = true)
protected String eventid;
@XmlElementRefs({
@XmlElementRef(name = "NODE_ID", namespace = "http://oasis-fp6.org/schemas/TSO/1_0", type = JAXBElement.class),
@XmlElementRef(name = "OTHER_EVENT_ID",
namespace = "http://oasis-fp6.org/schemas/TSO/1_0", type = JAXBElement.class)
})
@XmlElement(name = "GEO")
protected
List<EVENT.GEO> geo;
@XmlElement(name = "PREDICTED_CASUALTIES")
protected
List<EVENT.PREDICTEDCASUALTIES> predictedcasualties;
@XmlElement(name
= "TREND")
protected
String trend;
……..
public static class GEO {
@XmlElement(name = "DESCRIPTION",
required = true)
protected String description;
@XmlElement(name = "POSITION", required = true)
protected POSITION position;
@XmlElement(name = "WEATHER")
protected
List<String> weather;
@XmlElement(name = "TEXT")
protected
String text;
}
POSITION.java
public
class POSITION {
@XmlElement(name = "LOC_ID")
protected String locid;
@XmlElement(name = "NAME")
protected String name;
@XmlElement(name = "COORD")
protected POSITION.COORD coord;
…….
public static class COORD {
@XmlElementRefs({
@XmlElementRef(name = "LON", namespace = "http://oasis-fp6.org/schemas/TSO/1_0", type = JAXBElement.class),
@XmlElementRef(name = "HEIGHT", namespace = "http://oasis-fp6.org/schemas/TSO/1_0", type = JAXBElement.class),
@XmlElementRef(name = "LAT", namespace = "http://oasis-fp6.org/schemas/TSO/1_0", type = JAXBElement.class)
})
}
I hope this is enough to
understand what I’m working with. Sorry if I didn’t explain myself
correctly.
Thanks in advance,

Checking an xml field
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.

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
== “
Then
Action
instead of
when
OASISTSO10($e: EVENT)
OASISTSO10($e.GEO.POSITION.LOCID == “
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
<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
