Transform response to plain-text using wso2 esb 4.0.6 - web-services

Question

I'm new to web-service and somehow I have created a simple web-service over http/https using wso2 esb 4.0.6. Now my requirement is to remove the tag from response i.e. i need plain text in response, below code snippets will give u a brief idea of my requirement.
<case regex="POST">
<property name="HTTP_METHOD" value="POST" scope="axis2" type="STRING"/>
<enrich>
<source type="inline" clone="true">
<success xmlns="">Your request for subscription is being processed.</success>
</source>
<target type="body"/>
</enrich>
<header name="To" action="remove"/>
<property name="NO_ENTITY_BODY" scope="axis2" action="remove"/>
<property name="RESPONSE" value="true" scope="default" type="STRING"/>
<property name="ContentType" value="text/plain" scope="axis2"/>
</case>
I'm able to get the below response <success>Your request for subscription is being processed.</success>
I just want to remove the <success> </success> tags from the response.
Thanks in advance

May be this is bit late, but I too have came across this recently, and here's how you can make it work.
Make sure in ESB/repository/conf/axis2/axis2.xml plainTextFormatter is enabled.
In your proxy service set 'messageType' property as shown below
Add a payload text element. Please refer to the out sequence of the sample proxy service given below
<outSequence>
<payloadFactory>
<format>
<ms11:text xmlns:ms11="http://ws.apache.org/commons/ns/payload">$1</ms11:text>
</format>
<args>
<arg xmlns:ns="http://www.wso2.org/types" expression="$body/ns:greetResponse/return/text()"/>
</args>
</payloadFactory>
<property name="messageType" value="text/plain" scope="axis2"/>
<log level="full"/>
<send/>
</outSequence>
In this scenario my response from the backend service (HelloService) is as follows.
<?xml version='1.0' encoding='utf-8'?>
<soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope">
<soapenv:Body>
<ns:greetResponse xmlns:ns="http://www.wso2.org/types">
<return>Hello World, Test !!!</return>
</ns:greetResponse>
</soapenv:Body>
</soapenv:Envelope>
See below the request and response for the GET request using curl command
curl -X GET "http://localhost:8280/services/TestProxy/greet?name=Test" -v
* About to connect() to localhost port 8280 (#0)
* Trying 127.0.0.1... connected
> GET /services/TestProxy/greet?name=Test HTTP/1.1

Simply define the full envelope as inline source.
Eg:
<inSequence>
<enrich>
<source type="inline" clone="true">
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body> Your request for subscription is being processed. </soapenv:Body>
</soapenv:Envelope>
</source>
<target type="envelope"/>
</enrich>
<header name="To" action="remove"/>
<property name="RESPONSE" value="true" scope="default" type="STRING"/>
<property name="Content-Type" value="text/plain" scope="transport" type="STRING"/>
<send/>
</inSequence>
