XML HTTP Data Source

I am trying to create a report based on an html xml data source. But am having issues with the Dataset. My html xml is:

- <ReportExample xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/Mustang.Web.Controllers">
  <DoubleExample>456.789</DoubleExample>
  <Name>Report Name</Name>
  <ProviderType>INNHF</ProviderType>
  <ReportId>3</ReportId>
  <ReportType>costprofile</ReportType>
  </ReportExample
