How we can count the objects in Iterator using wso2esb - wso2

Question

I am getting array list from my front end that i need to insert into a table using Wso2esb and dss i have almost done that functionality using iterator.I need to give response to front end whenever insertion over of that array list. i wish to count the any obejects which is iterating number of times
my code is like this
<iterate continueParent="true"
id="QuestionListMobile"
expression="//QuestionsList">
<target>
<sequence>
<property name="ttemplateformid"
expression="get-property('ttemplateformid')"
scope="default"
type="STRING"/>
<payloadFactory>
<format>
<p:Insert_ttemplatedetails_Mobile_Op xmlns:p="http://ws.wso2.org/dataservice">
<xs:templateformid xmlns:xs="http://ws.wso2.org/dataservice">$1</xs:templateformid>
<xs:formtemplatesectiondetailid xmlns:xs="http://ws.wso2.org/dataservice">$2</xs:formtemplatesectiondetailid>
<xs:questionid xmlns:xs="http://ws.wso2.org/dataservice">$3</xs:questionid>
<xs:weightage xmlns:xs="http://ws.wso2.org/dataservice">0</xs:weightage>
<xs:rank xmlns:xs="http://ws.wso2.org/dataservice">$4</xs:rank>
<xs:score xmlns:xs="http://ws.wso2.org/dataservice">$5</xs:score>
<xs:remarks xmlns:xs="http://ws.wso2.org/dataservice">$6</xs:remarks>
<xs:feedback xmlns:xs="http://ws.wso2.org/dataservice">$7</xs:feedback>
</p:Insert_ttemplatedetails_Mobile_Op>
</format>
<args>
<arg expression="get-property('ttemplateformid')"/>
<arg expression="//sectionQuestionMapId/text()"/>
<arg expression="//QuestionId/text()"/>
<arg expression="//Rank/text()"/>
<arg expression="//answer/text()"/>
<arg expression="//remark/text()"/>
<arg expression="//Feedback/text()"/>
</args>
</payloadFactory>
<log level="full"/>
<send receive="QuestionsInsertion_Seq3">
<endpoint>
<address uri="http://localhost:9764/services/ttemplatesectiondetail_DataService/"
format="soap11"/>
</endpoint>
</send>
<log level="full"/>
</sequence>
</target>
</iterate>
i am doing well how can i know above how many arrays i got
<sequence xmlns="http://ws.apache.org/ns/synapse"
name="QuestionsInsertion_Seq3"
onError="fault">
<property name="FORCE_ERROR_ON_SOAP_FAULT"
value="true"
scope="axis2"
type="STRING"/>
<property xmlns:f="http://ws.wso2.org/dataservice"
xmlns:ns="http://org.apache.synapse/xsd"
name="ttemplatedetailid"
expression="//f:ttemplatedetailid/text()"
scope="default"
type="STRING"/>
<log>
<property xmlns:ns="http://org.apache.synapse/xsd"
name="Total"
expression="count(//QuestionId/text())"
scope="default"
type="STRING"/>
<property xmlns:f="http://ws.wso2.org/dataservice"
xmlns:ns="http://org.apache.synapse/xsd"

expression="//f:ttemplatedetailid/text()"/>
</log>
I am loging QuesionId count but i am not getting i am getting as total is 1.0 only
i need to count in proxy only or in sequence

You can not count the iteration..What you are trying now is, you are getting DS response in your receive sequence, and from the response you are trying to read a value. So, check your response, and see what you are getting from endpoint
