<proxy xmlns="http://ws.apache.org/ns/synapse" name="test123" transports="https,http" statistics="disable" trace="disable" startOnLoad="true">
   <target>
      <inSequence>
         <property name="test" expression="get-property('registry','conf:/test.xml')" scope="default" type="OM" />
         <log level="custom">
            <property name="test.b" expression="$ctx:test//b" />
         </log>
      </inSequence>
      <outSequence>
         <send />
      </outSequence>
      <endpoint>
         <address uri="http://localhost:8280/services/Version" />
      </endpoint>
   </target>
   <publishWSDL uri="http://localhost:8280/services/Version?wsdl" />
   <policy key="conf:/repository/axis2/service-groups/test123/services/test123/policies/61afea637b914422e1753dde4e88864cc199fecbb66084e2" />
   <policy key="conf:/repository/axis2/service-groups/test123/services/test123/policies/urn:version" />
</proxy> 


Then create an xml file in the config registry with following content.


<a>Hello<b>WSO2</b></a>


You will see the following log
