Re: xpath for header

[Claus Ibsen]

Hi

Well Camel usually have a easier way than wring 20 lines of code.

There is a static evaluate/matches method on XPathBuilder you can pass
in your xpath + data, eg

boolean matches = XPathBuilder.xpath("/foo/bar/@xyz").matches(context,
"<foo><bar xyz='cheese'/></foo>")
