Apache Camel conditional routing

I have a service which has two operations.

RegisterUser
UpdateUser

I have a camel rout:

<camel:route id="myRoute">
    <camel:from uri="cxf:bean:myListenerEndpoint?dataFormat=POJO&amp;synchronous=true" />            
    <camel:bean ref="processor" method="processMessage"/>
    <camel:to uri="xslt:file:resources/service/2.0.0/UserRegistration.xsl"/>
    <camel:to uri="cxf:bean:myTargetEndpoint"/>
</camel:route>

In my processor bean, when I specify:

RegisterUser registerUser = exchange.getIn().getBody(RegisterUser.class);

I get the register user object. Everything works fine. The problem is that I want camel to route my request conditionally, for e.g:

If the service operation is RegisterUser I want to route the message to my specific bean and if the service operation is UpdateUser I want to route the message to the other bean.

I have tried to use camel xPath, but it not seems to be working.

<camel:route id="myRoute">
    <camel:from uri="cxf:bean:myListenerEndpoint?dataFormat=POJO&amp;synchronous=true" />  
    <camel:choice>
        <camel:when>
            <camel:xpath>
                //RegisterUser
            </camel:xpath>
            <camel:bean ref="processor" method="processMessage"/>
            <camel:to uri="xslt:file:resources/service/2.0.0/UserRegistration.xsl"/>
        </camel:when>
    </camel:choice>                        
    <camel:to uri="cxf:bean:myTargetEndpoint"/>
</camel:route>

I was searching how to set up camel to route to the different targets but did not find anything. Maybe somebody knows where might be the problem?
