Error: The XmlDb Query Is Invalid

Hi,

I was working on the MSDN Tutorial "Using XML Data in a Report", Lesson 2: Defining a Report Dataset for an ADO.NET DataSet from a Web Service at the follwoing link http://msdn2.microsoft.com/en-us/library/aa337489.aspx

When i run the following query, everything goes as expected (i.e. the displayed data is the extracted data from all XML elements and attributes down to the leaf node on the first XML path it finds in the dataset )

<Query>
<SoapAction>
http://tempuri.org/GetEmployeeManagers
</SoapAction>
<Method Namespace="http://tempuri.org/"
Name="GetEmployeeManagers">
</Method>
</Query>

But when i add the other section to specify the elements to be used in retrieving the data

<ElementPath IgnoreNamespaces="True">
GetEmployeeManagersResponse {}/
GetEmployeeManagersResult/diffgram{}/
Results {}/Table
</ElementPath>

the following error is dispalyed:

===================================

An error occurred while creating a data extension command.
The XmlDP query is invalid. (Microsoft Report Designer)

The XmlDP query is invalid. (Microsoft.ReportingServices.DataExtensions)

There are multiple root elements. Line 9, position 2. (System.Xml)

===================================

I would appreciate much if u helped me in this problem

Thank you,
