camel: split the message into multiple processing paths - apache-camel

Question

My input message:
<file>
<node1>
...
</node1>
.....
<node10>
.....
</node10>
</file>
I want to:
Process the whole file using stylesheet and output to Dest A
For a few elements in the file (say, node1, node3 and node7) I want to extract them and output the content of each individually to Dest B
I know how to process the file using stylesheet but I'm at a loss how to do the other, let alone combine them together.
I'm looking for something like:
from(direct:start).magic_split(
to("xslt:mysheet").to("destA"),
setBody(xpath("//node1").to("destB"),
setBody(xpath("//node3").to("destB"),
setBody(xpath("//node7").to("destB"),
).transform(constant(responseOK);

Answer 1

if you can split the XML, then each node is put in it's own exchange, if you can identify the node after it is split, then you can use a Content Based Router to route the exchange to the appropriate destination. This might require a custom splitter bean, or you might be able to do it from xpath if the nodes are named nodeX where X is a number.

Answer 2

Use the Wire Tap pattern. This pattern allows you to route messages to a separate location while they are being forwarded to the ultimate destination:
from("cxf:bean:submitOrder")
.wireTap("direct:tap")
.beanRef("customBean2");
from("direct:tap")
.to("xslt:my.xsl")
.beanRef("customBean1);

Answer 3

For what I needed, custom beans did the job well. The only thing I had to figure out was how to restore the message to the original content. I guess there is a more elegant way of doing it but works fine:
from("cxf:bean:submitOrder")
.setProperty("originalData", simple("${in.body}")) //save original input msg
.to("xslt:my.xsl").beanRef("customBean1)
.setBody(simple("${property.originalData}")) //restore original message
.beanRef("customBean2");
