Splitted XML Aggregator processor

Version: 17.07

Supported Since: 17.07

What is a Splitted XML Aggregator processor?

A Splitted XML Aggregator processor is a processing element which accepts messages or responses splitted by an XML Aplitter processing element with an XML payload, aggregates the splitted messages of a single parent message into a single accumulated message by a provided XPath expression. Once the last splitted message/response reached the aggregator, it will complete the aggregation and give the resulting message for the processing by the next processing element. However all messages prior to the last message would be aggregated but dropped with SUCCESS status by this processing element.

In order to use this processing element, you must first select the EIP Routing dependency from the processor list when you are creating an empty Ultra project. If you have already created a project, you can add this dependency via Component Registry. From Tools menu, select Ultra Studio → Component Registry and from the Processors list, select the EIP Routing dependency.

Alternatively, you can add the following dependency to the maven pom.xml manually.

<dependency>
    <groupId>org.adroitlogic.x.processors</groupId>
    <artifactId>x-processor-eip-routing</artifactId>
    <version>17.07</version>
</dependency>
