how to use for each in mule - mule

Question

***I have a xml ---***
<DBOperation>
<ListOfOperation>
<operation>
<operationName>Insert</operationName>
<input>
<empid>3</empid>
<name>saurabh</name>
</input>
<operationName>Delete</operationName>
<input>
<empid>3</empid>
</input>
<operationName>insert</operationName>
<empid>3</empid>
<name>saurabh</name>
<operationName>update</operationName>
<input>
<empid>3</empid>
<name>raj</>
</input>
</operation>
</ListOfOperation>
</DBOperation>
I want to send this xml as a soap message but the entire operation at once such that using one request i can perform all the operations using choice routing....what is the most effecient method to do this in mulesoft...and if using for each what should be my collection tab configuration?

Answer 1

Do you need create a webservice that returns this xml as response?
If yes, This might help you:
JAVA (NO MULE)
Create a java bean and properties that match exactly with your xml : Response.java
Create a java class with one operation, that return this Response. And using some library, create your webservice:
#WebService
public class WebService {
public Response operation_name(Request request){
}
}
Request class if you need some parameter.

Finally when you need return xml as response, use a unmarshall process to convert your xml file to Response.java.

MULE
I think are the same steps because Mule can create a web service from a java class:

<flow name="dbopps">
<http:listener config-ref="HTTP_Listener_Configuration1" path="/" doc:name="HTTP"/>
***<foreach collection="#[xpath://.[xpath:local-name()='DBOperation']/*[xpath:local-name()='ListOfOperation']/*[xpath:local-name()='operation']]" doc:name="For Each" >***
<mulexml:dom-to-xml-transformer doc:name="DOM to XML"/>
<logger message="#[payload]" level="INFO" doc:name="Logger"/>
<set-variable variableName="name" value="#[xpath('//operationName').text]" doc:name="Variable"/>
<logger message="#[flowVars.name]" level="INFO" doc:name="Logger"/>
<choice tracking:enable-default-events="true" doc:name="Choice">
<when expression="#[flowVars.name == 'Insert']">
<db:insert config-ref="MySQL_Configuration" doc:name="Insert">
<db:parameterized-query><![CDATA[Insert into employees(empid,name) values ('43',#[xpath('//name').text])]]></db:parameterized-query>
</db:insert>
</when>
<when expression="#[flowVars.name == 'Delete']">
<db:delete config-ref="MySQL_Configuration" doc:name="Delete">
<db:parameterized-query><![CDATA[Delete from employees where empid='10']]></db:parameterized-query>
</db:delete>
</when>
</foreach>
<set-variable variableName="id" value="#[xpath://.[xpath:local-name()='DBOperation']/*[xpath:local-name()='ListOfOperation']/*[xpath:local-name()='operation']/*[xpath:local-name()='operationName']']" doc:name="Variable"/>
<set-payload value="<a> hello </a>" doc:name="Set Payload"/>
</flow>
This works fine for me you can check the collection tab configuration.
