Available as of Camel 2.9
The StAX component allows messages to be process through a SAX ContentHandler.
Another feature of this component is to allow to iterate over JAXB records using StAX, for example using the Splitter EIP.
Maven users will need to add the following dependency to their
pom.xml for this component:
From Camel 2.11.1 onwards you can lookup a
org.xml.sax.ContentHandler bean from the Registry using the # syntax as shown:
Usage of a content handler as StAX parser
The message body after the handling is the handler itself.
Here an example:
Iterate over a collection using JAXB and StAX
First we suppose you have JAXB objects.
For instance a list of records in a wrapper object:
Then you get a XML file to process:
The StAX component provides an
StAXBuilder which can be used when iterating XML elements with the Camel Splitter
stax is a static method on
org.apache.camel.component.stax.StAXBuilder which you can static import in the Java code. The stax builder is by default namespace aware on the XMLReader it uses. From Camel 2.11.1 onwards you can turn this off by setting the boolean parameter to false, as shown below:
The previous example with XML DSL
The example above could be implemented as follows in XML DSL
