Raul Kripalani commented on CAMEL-325:
--------------------------------------
A few questions about the following code block:
from("file://foo").
loop().xpath("/something = 'abc').
to("blah");
- What EXACTLY would this do? Would it keep on sending the message to endpoint
"blah" WHILE the XPath evaluates to true?
- What exactly is fed back to the xpath condition to re-evaluate the looping
condition after every iteration? I mean, when would this become false?
- I'm not sure if the semantics of this construct are clear. I mean, is the
looping done UNTIL the XPath evaluates to true? Or does it loop WHILE the XPath
evaluates to true?
> support a loop operation in the routing DSL

>
> It'd be nice to do something like
> {code}
> from("file://foo").
> loop(100).
> to("blah");
> {code}
> Or use some kinda expression
> {code}
> from("file://foo").
> loop().xpath("/something = 'abc').
> to("blah");
> {code}
> To essentially add a loop inside a route. Testing is the main use case for
> this really. e.g. take a few production messages and generate zillions of
> test case messages
> {code}
> from("file://foo").
> loop(100).
> bean(MyRandomizerTransform.class).
> to("blah");
> {code}
