SSIS: XML not being inserted into table

In SSIS I have a generated XML file based on a webservice. I need to read the file to generate a dataset.
The problem that I have is that the "XML Source" is not reading the file correctly. I'm not getting any data. This fact is based on a Data Viewer that I have defined.

There is an inline schema defined in the XML, so I don't need to define a location for the XSD location.
When I click Columns in the "XML Source Editor" I see the different columns that are available.

XML Source:

<?xml version="1.0" encoding="utf-16"?>
<DataSet>
  <xs:schema id="NewDataSet" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">

        <lastupdate>19/08/2010</lastupdate>
      </Table1>
    </NewDataSet>
  </diffgr:diffgram>
</DataSet>

Any ideas on how to get the XML Source to read the XML file so that I can generate a dataset(object) out of this XML?

Input much appreciated!!
