Split: how to leave message untouched?
hello,
I split messages using
from(incomingQueue)
.startupOrder(1)
*.split().tokenizeXML("update", "dbStream")*
.convertBodyTo(Document.class)
.choice()
.when().xpath(SUBSCRIPTION_XPATH)
.to(AGGREGATE_MESSAGES)
.otherwise()
.to(PRODUCERS)
.end();
however, when the XML does not contain neither <update> nor <dbStream>, the
routing just seems to stop. Is there a way to let messages through that are
not applied by the split?
According to http://camel.apache.org/splitter.html
http://camel.apache.org/splitter.html , "The Splitter will by default return
the original input message", but I can not see that happen in this case.
Using Camel 2.9.2

Hi
Easier to crete a route for the splitter
And then have another route that does the filter. And use the direct
endpoint to call the other route.
from X
filter bla
to splitme
end
common stuff here
from direct:splitme
split tokenize xml

if the filter() Predicate returns false, I assume the processing stops there?
I would like to go beyond the split() and carry on with the .convertBodyTo()
etc. in case the filter() returns false.
I tried something like
from(incomingQueue)
.choice()
.when().xpath(UPDATE_XPATH)
.split().tokenizeXML("update", "dbStream")
.end()
.convertBodyTo()
....
and even
from(incomingQueue)
.split(xpath(UPDATE_XPATH).tokenizeXML("update", "dbStream"))
.end()
.convertBodyTo()
but they are not correct. Don't know how to solve this

You can use the filter EIP to filter out message that are not <update>
XML messages.
The tokenizeXML requires the message structure to be XML and have a
root tag named <update> which contains a list of child tags named
<dbStream>.
