How can I output XML with different queries - sql

Question

I am struggling at outputting XML the correct way. I'm trying to generate XML document with SQL Server query, which gives my the following:
CODE USED:
SELECT Plate, tbl_veiculos.ID, Brand, Model, Origin, Color
FROM tbl_veiculos, tbl_veiculo_spec
WHERE tbl_veiculos.ID = tbl_veiculo_spec.ID AND tbl_veiculos.ID = 1
FOR XML PATH ('Vehicle'), TYPE, ROOT('VehicleList')
RESULT:
<VehicleList>
<Vehicle>
<Plate>34-23-nd</Plate>
<ID>1</ID>
<Brand>Mercedes-Benz</Brand>
<Model>A140</Model>
<Origin>Germany</Origin>
<Color>Red</Color>
</Vehicle>
</VehicleList>
Which is to a certain way what I need. The problem comes when I try to merge it with other query output. I know this doesn't explain well so I'll show you an harcoded version of what I want.
<VehicleList>
<Vehicle>
<Plate>34-23-nd</Plate>
<ID>1</ID>
<Brand>Mercedes-Benz</Brand>
<Model>A140</Model>
<SellerInfo>
<Name>Someone Special</Name>
<Street>Oxfod Court 1231</Street>
</SellerInfo>
<Origin>Germany</Origin>
<Color>Red</Color>
</Vehicle>
</VehicleList>
<SellerInfo> comes from other table.

You can use subquery as below:
SELECT Plate, tbl_veiculos.ID, Brand, Model,
(select Name, Street from sellerInfo where id = t1.id --use id to join sellerInfo table
for xml Path(''), type) as SellerInfo,
Origin, Color,
FROM tbl_veiculos t1 inner join tbl_veiculo_spec ts
on tbl_veiculos.ID = tbl_veiculo_spec.ID AND tbl_veiculos.ID = 1
FOR XML PATH ('Vehicle'), TYPE, ROOT('VehicleList')
