Camel Spring XML working with variables from xml message

[mtod09]

I'm developing a route that will read the incoming xml message and create a
new message to pass to an outbound route.

I need to extract some data via xpath then concat the data  elements to send
to a new route.

Example

<msg1>
   <data1>My</data1>
   <data2>home</data2>
<msg1>

var1 = data1
var2 = data2

var3 = var1 + " " + var2

var3 = "My home"

I'm not sure how to do this with Spring XML does any one have an example or
pointer?

My Route so far:

    <camel:camelContext id="myCamel"
xmlns="http://camel.apache.org/schema/spring";>

        <camel:dataFormats>
            <camel:syslog id="mySyslog"/>
        </camel:dataFormats>

        <camel:route>
            <camel:from uri="activemq:queue:syslogMessages"/>
            
            <setHeader headerName="DateValue">
                <xpath
resultType="String">/km:FMIMessage/km:Header/km:Payload/se:SystemEvent/se:EventTime/text()</xpath>
            </setHeader>
            <setHeader headerName="PRI">
                <xpath
resultType="String">/km:FMIMessage/km:Header/km:Payload/se:SystemEvent/se:LevelID/text()</xpath>
            </setHeader>
            <setHeader headerName="Hostname">
                <xpath
resultType="String">/km:FMIMessage/km:Header/km:Payload/se:SystemEvent/se:ServerName/text()</xpath>
            </setHeader>
            <setHeader headerName="Message">
                <xpath
resultType="String">/km:FMIMessage/km:Header/km:Payload/se:SystemEvent/se:MessageText/text()</xpath>
            </setHeader>
            <setHeader headerName="SyslogMsg">
                <constant>"<2> DateValue Hostname Message"</constant>
            </setHeader>
            
            

            <camel:marshal ref="mySyslog"/>
            <camel:to uri="mina:udp://localhost:514?sync=false"/>
            

        </camel:route>

    </camel:camelContext>

Thanks 

Mike
