i. First Open Notepad and write below code till </root>:

<root>
<%begindetail%>
<%insert_data_here%>
<%enddetail%>
</root>

Now Save it as c:\sqlexamples\template.tpl

Next you open SQL Server Query Editor and type:

sp_makewebtask @outputfile = 'c:\myxmlfile.xml',
    @query = 'select * from sysobjects for xml auto',
    @templatefile = 'c:\sqlexamples\template.tpl'

The Result is a XML-File!

Happy Coding! ;)
