Create a table in iReports using XmlDataSource - jasper-reports

Question

I'm trying to create a table using XmlDataSource, but it neither printing the table structure nor showing the data. I'm using iReport 4.7.1. Kindly help.
What I have done is:
Created a new blank report
Created an xml datasource
Selected /sendDetail/results as the record node
Created a table with the selected fields
Below is the .jrxml file I'm using:
<?xml version="1.0" encoding="UTF-8"?>

Answer 1

You need to:
Change your main dataSet's queryString to:
<queryString language="xPath">
<![CDATA[/]]>
</queryString>
Replace your table's datasetRun declaration with:
<datasetRun subDataset="Dataset" uuid="33620359-7c04-4c08-9f6c-a18d9c5eb044">
<dataSourceExpression><![CDATA[((net.sf.jasperreports.engine.data.JRXmlDataSource)$P{REPORT_DATA_SOURCE}).subDataSource("/sendDetail/results")]]></dataSourceExpression>
</datasetRun>
