The reports based on XML is perfectly displayed in development Environment.
But than uploaded to Server, the following occurs:
- An error has occurred during report processing.
- An attempt has been made to use a data extension 'XML' that is not registered for this report server.
Help needed, thank you.

SQL Server Reporting Services - data extension 'XML'
TDAVISJR
Thank you for the answer!
Is there are any way to revoke this limitation
XML is a great technology, and it does not look like a "big deal" for Microsoft to let developers use XML as the DataSource for the Reporting, even in Express Edition.
Thank you very much again,
Alfred.

<
Data><
Extension Name="SQL" Type="Microsoft.ReportingServices.DataExtensions.SqlConnectionWrapper,Microsoft.ReportingServices.DataExtensions"/><
Extension Name="OLEDB" Type="Microsoft.ReportingServices.DataExtensions.OleDbConnectionWrapper,Microsoft.ReportingServices.DataExtensions"/><
Extension Name="OLEDB-MD" Type="Microsoft.ReportingServices.DataExtensions.AdoMdConnection,Microsoft.ReportingServices.DataExtensions"/><
Extension Name="ORACLE" Type="Microsoft.ReportingServices.DataExtensions.OracleClientConnectionWrapper,Microsoft.ReportingServices.DataExtensions"/><
Extension Name="ODBC" Type="Microsoft.ReportingServices.DataExtensions.OdbcConnectionWrapper,Microsoft.ReportingServices.DataExtensions"/><
Extension Name="XML" Type="Microsoft.ReportingServices.DataExtensions.XmlDPConnection,Microsoft.ReportingServices.DataExtensions"/> </Data>ToddGibbs
By default, the RSReportServer.config file of RS 2005 should contain the registration for the Xml data extension in the <Data> section:
<Extension Name="XML" Type="Microsoft.ReportingServices.DataExtensions.XmlDPConnection,Microsoft.ReportingServices.DataExtensions" />
Is it present in your case

Yes, SQL Express Advanced Edition is restricted to relational data sources. Check this link for more details: http://www.microsoft.com/sql/technologies/reporting/rsfeatures.mspx
