Issue with SetHeader / Xpath

[contactreji]

Hi

Would be nice if you guys can help me with the proper way os using Xpath in
Spring DSL

I am trying to extract a value from incomign XML file using Xpath and trying
to set it to header. The route is as follows
*
<route id="b2mml_ftp_pickup">
                        <from
                        
uri="ftp://{{ftpUser}}@{{ftpHost}}{{path}}?password={{ftpPassword}}&amp;move=/in/b2mml/arc";
/>
                        <log message="Received file ${file:name} from MES" />
                        <convertBodyTo type="java.lang.String">
                                <description>&lt;from 
uri="file://D:/input"/&gt;</description>
                        </convertBodyTo>
                        
                        <setHeader headerName="ID">
                                 <xpath
resultType="java.lang.String">//ProductionResponse/ProductionRequestID/text()</xpath>
 
                        </setHeader>
                        <log message="The ID extracted is ${in.header.ID}" />
                        <to uri="activemq:processXML" />
                </route>*


Unfortunately the output doesn't contain the extracted value. The output is
as follows.
