The Java language is maxed out with the builder pattern and generics.
What you actually do is to kinda call a sub method (the xpath) and
then want to go back to the scope used before (eg from setHeader) but
that is not always possible with regular Java.
That is why I prefer to pass in the xpath as a parameter to the
setHeader method
.setHeader("foo", xpath("/bar"))
You then need to use static import
import static org.apache.camel.builder.xml.XPathBuilder.xpath;

No :)
That person wanted to set the filename based on parts of xpath.
So if you want to extract from xpath and add .xml as file extension,
and/or maybe have a fixed prefix for the file name, you can do
that with some xpath concat magic. I am no xpath lover and cant
remember the syntax for using those xpath functions.
