Generate differently formatted XML file from SQL statement

My input data looks like this:
Table: t1
Item       Offer
ab123   O1234
ab235   O3265

My goal is to build an XML file, using SQL, which looks like this:
<Items>
  <Item>
    <Style>DT130 48                 </Style>
    <SourceCodeList>
      <SourceCode>708YDRP3</SourceCode>
    </SourceCodeList>
  </Item>

Here's the code I am using in SQL:
SELECT [item] as "Style",
       (select offer as "SourceCode" from t1 t
where t.[item] = c.[item]  for xml path (''), type) as "SourceCodeList"
FROM   (select distinct [item] from t1) c
FOR XML PATH ('Item'), type, elements, Root ('Items')

Unfortunately, the code generates a file with an extra element with each record (<Item />:  
<Items>
  <Item />
  <Item>
    <Style>DT130 48                 </Style>
    <SourceCodeList>
      <SourceCode>708YDRP3</SourceCode>
    </SourceCodeList>
  </Item>

Please advise how to remove.  
Alternately -- My preference would be to build the ouptut file using SSIS.  Advice for how to do this would be appreciated!  Thanks!
