<x><![CDATA[
require 'rexml/document'
include REXML
def transformRequest(mc)
newRequest= Document.new '<m:getQuote xmlns:m="http://services.samples">'<<
'<m:request><m:symbol></m:symbol></m:request></m:getQuote>'
newRequest.root.elements[1].elements[1].text = mc.getPayloadXML().root.elements[1].get_text
mc.setPayloadXML(newRequest)
end
def transformResponse(mc)
newResponse = Document.new '<m:CheckPriceResponse xmlns:m="http://services.samples/xsd"><m:Code>' <<
'</m:Code><m:Price></m:Price></m:CheckPriceResponse>'
lastPrice=mc.getPayloadXML().root.elements[1].get_elements('*:last')
code=mc.getPayloadXML().root.elements[1].get_elements('*:symbol')
newResponse.root.elements[1].text =code[0].get_text
newResponse.root.elements[2].text =lastPrice[0].get_text
mc.setPayloadXML(newResponse)
end
