Hi
You can use the Camel @Xpath annotation on a 2nd parameter in that
method signature
public boolean match(String username, @XPath("/Example/User") String user) {
You may have to fiddle a bit to get the xpath expression working.
Also sometimes you may have to use /text() to tell it to return the
text content of the xml node.
