HTML Report generation from Dynatrace ANT Tasks

Hi,

I am having issues generating the html report using the example Dynatrace target below. 

1st target: "<DtReport dashboardname="easyTravel Database" source="live:easyTravel" createHtml="true" xmlToFile="./results/report.xml"/>" 

Once the 1st target is executed, I see the updated report.xml file and when I open the index.html or overview.html, i dont see the body of the report. Can someone try using below task and let me know how you got it working? 

2nd Target: "<DtReport dashboardname="RulesDashboard" iteratorDashboard="TransactionDashboard" source="live:GoSpace" createHtml="true" reportDir="./results"/>" 

I dont know how to exploit this target options like iteratordashboard. Can some one explain the use case of this dtreport task and how an example report would look like?

<target name="DashboardReporting">
<!-- Queries a single dashboard and puts the result out to an XML File using XSLT to transform it to HTML -->

<DtReport dashboardname="Test" source="live:GoSpace" createHtml="true" xmlToFile="./results/report.xml"/>

<!-- Creates a dashboard report for every transaction or webrequest that is on the iterator dashborad
outputs all files in the report directory
an overview page is created to navigate through all result files
-->
<DtReport dashboardname="RulesDashboard" iteratorDashboard="TransactionDashboard" source="live:GoSpace" createHtml="true" reportDir="./results"/>

<!-- Make sure that - when using Business Transactions on the Iterator or Data Dashboard to reanalyze stored sessions before running the report
Either us DtReanalyzeSession or specify the reanalyzeSession="true" property for DtReport
-->
</target>
