XPath + DOM-reuse

[jhm]

I have a route dispatching an exchange according to a XPath evaluation to
different targets.

Sadly it doesnt perform very well. I think that the DOM is built for every
XPath evalutation.

Is it true? Can we configure Camel to reuse the DOM?

 

I think in this Route Camel builds the same DOM 4 times.

 

public class MyRouter extends RouteBuilder {

    @Override

    public void configure() throws Exception {

        Namespaces v1 = new Namespaces("v1", "...");

        Namespaces v2 = new Namespaces("v2", "...");

           

        from("direct:dispatcher")

            .id("dispatcher")

            .choice()

                .when().xpath("/v1:TypeA",
v1).to("bean:beanA?method=execute")

                .when().xpath("/v1:TypeB",
v1).to("bean:beanB?method=execute")

                .when().xpath("/v2:TypeA",
v2).to("bean:beanC?method=execute")

                .when().xpath("/v2:TypeB",
v2).to("bean:beanD?method=execute")

                // many more when().xpath().to() statements

            .end();

    }

}
