This is not a Drools problem, however...

You are using a Domain Specific Language (DSL) to transform rules into Drools Rule Language (DRL). If you have written the DSL you should know how it works; if you haven't, then there should be a documentation telling you what the parameters of
   xpathEquals  "/IATA/messageaudit/@messageVersion" "FSU/13/RCS"
mean, and this would immediately solve your problem. If you had that documentation (why don't you have it?), it would say that the first parameter is an XPath expression and the second a value to match at the location the first expression identifies.

Now, when you use SW using XPath with XML, you should know the basics about XPath. If you don't - w3c has some good tutorials, see the one on XPath, here.

The XPath used denotes an attribute and therefore your rules will only work if messageVersion is an attribute of the element /IATA/messageaudit. In the second XML, all values are elements below that element.

Hi

iam new to drools rules my problem is


iam receiving message in xml format so using drools have to route it my
drools rules work when the xml message is the format as below

<?xml version="1.0" encoding="UTF-8"?>
<IATA>
<messageaudit senderId="125" receiverId="FFCategory"
dateTimeOfMessage="19:00"
messageVersion="FSU/13/RCS" airwaybill="125-1234565" />
<fsurcs AwbNumber="125-1234565" origin="HYD" destination="KUL"
totalPieces="T40" totalWeight="K200"
statusCodeConsignmentRecieveDFromShipperOrAgent="RCS"
dayAndMonthOfReceipt="02June" actualTimeOfGivenStatusEvent="19:00"
airportCodeOfReceipt="HYD"
totalOrPartNumberOfPices="T40" weightOfTotalOrPartOfPieces="K200"
nameOfAgentOfShipper="Shipper" osi="RcsMessage"/>
</IATA>

but if the xml is the format as below

<?xml version="1.0" encoding="UTF-8"?>
<IATA>
<messageaudit>
<senderId>125</senderId>
<receiverId>FFCategory</receiverId>
<dateTimeOfMessage>19:00</dateTimeOfMessage>
<messageVersion>FSU/13/RCS</messageVersion>
<airwaybill>125-1234565</airwaybill>
</messageaudit>
<fsurcs>
<AwbNumber>125-1234565</AwbNumber>
<origin>HYD</origin>
<destination>KUL</destination>
<totalPieces>T40</totalPieces>
<totalWeight>K200</totalWeight>
<statusCodeConsignmentRecieveDFromShipperOrAgent>RCS</statusCodeConsignmentRecieveDFromShipperOrAgent>
<dayAndMonthOfReceipt>02June</dayAndMonthOfReceipt>
<actualTimeOfGivenStatusEvent>19:00</actualTimeOfGivenStatusEvent>
<airportCodeOfReceipt>HYD</airportCodeOfReceipt>
<totalOrPartNumberOfPices>T40</totalOrPartNumberOfPices>
<weightOfTotalOrPartOfPieces>K200</weightOfTotalOrPartOfPieces>
<nameOfAgentOfShipper>Shipper</nameOfAgentOfShipper>
<osi>RcsMessage</osi>
</fsurcs>
</IATA>


it is not routing the message means not recognizing the drools and my drools
file is as follows

package com.jboss.soa.esb.routing.cbr

#list any import classes here.
import org.jboss.soa.esb.message.Message;
import org.jboss.soa.esb.message.format.MessageType;

expander XPathLanguage.dsl

#declare any global variables here
global java.util.List destinations;

rule "Blue Routing Rule using XPATH"
       when
               xpathEquals  "/IATA/messageaudit/@messageVersion" "FSU/13/RCS"
       then
           Log : "Blue Team";
               Destination : "blue";
end

rule "Red Routing Rule using XPATH"
       when
               xpathEquals  "/IATA/messageaudit/@messageVersion" "FSU/13/MAN"
       then
            Log : "Red Team";
               Destination : "red";
end

rule "Green Routing Rule using XPATH"
       when
               xpathEquals  "/IATA/messageaudit/@messageVersion" "FSU/13/DEP"
       then
            Log : "Green Team";
               Destination : "green";
end
