Yeah, Enrich mediator doesn't support multiple element. For your
requirement, we can use the following config,
<proxy name="PseudoProxy" transports="https http" startOnLoad="true"
trace="disable">
<target>
<inSequence>
<log level="full"/>
<enrich>
<source xmlns:ns2="http://brs.carbon.wso2.org";
xpath="//ns2:CustomerOrderProcessRequest/ns2:Customer/ns2:Order"/>
<target type="property" property="ORDERS_REQ"/>
</enrich>
<log level="custom">
<property name="BRS_REQ"
expression="get-property('ORDERS_REQ')"/>
</log>
<enrich>
<source type="inline">
<ns2:CalculatePriceRequest xmlns:ns2="
http://brs.carbon.wso2.org";>
<ns2:foo/>
</ns2:CalculatePriceRequest>
</source>
<target type="body"/>
</enrich>
<enrich>
<source type="property" property="ORDERS_REQ"/>
<target xmlns:ns2="http://brs.carbon.wso2.org";
xpath="//ns2:CalculatePriceRequest/ns2:foo"/>
</enrich>
<log level="full"/>
</inSequence>
<outSequence>
<log/>
</outSequence>
</target>
</proxy>
But this only copies the first order element only. So, IMO we need to add
this capability to enrich mediator.
resulting message:
