org.apache.camel.component.xslt.XsltAggregationStrategy
All Implemented Interfaces:
AutoCloseable, org.apache.camel.AggregationStrategy, org.apache.camel.CamelContextAware, org.apache.camel.Service, org.apache.camel.ShutdownableService, org.apache.camel.spi.HasCamelContext, org.apache.camel.StatefulService, org.apache.camel.SuspendableService
public class XsltAggregationStrategy extends org.apache.camel.support.service.ServiceSupport implements org.apache.camel.AggregationStrategy, org.apache.camel.CamelContextAware
The XSLT Aggregation Strategy enables you to use XSL stylesheets to aggregate messages.

Since XSLT does not directly support providing multiple XML payloads as an input, this aggregator injects the new incoming XML document (newExchange) into the oldExchange as an exchange property of type Document. The old exchange therefore remains accessible as the root context. This exchange property can then be accessed from your XSLT by declaring an <xsl:param /> at the top of your stylesheet: <xsl:param name="new-exchange" /> <xsl:template match="/"> <xsl:copy-of select="/ElementFromOldExchange" /> <xsl:copy-of select="$new-exchange/ElementFromNewExchange" /> </xsl:template> The exchange property name defaults to new-exchange but can be changed through setPropertyName(String).

Some code bits have been copied from the XsltEndpoint.
