I suggest something like this:
from("direct:start")
.filter(new Predicate() {
@Override
public boolean matches(Exchange exchange) {
String text =
exchange.getIn().getHeader("mySpecialXPathHeader", String.class);
return new
XPathExpression(text).createPredicate(exchange.getContext()).matches(exchanges);
}
})
.to("mock:result");
In an ideal world, you should be able to do something like this:
from("direct:start").
filter().xpath(header("mySpecialXPathHeader")).
to("mock:result");
May you consider to open a JIRA for it [1]?
