ok Jeff i solved problem , using "doc" was a bad mistake :) thanks for
your support ,here is the last codes
while reader.read
case reader.name
when "Brand_name"
name_from_xml = reader.read_string
Brand.create( :name => name_from_xml )
end
end
----------------------------
now i have to solve another problem :) do you know how can i get a
brand_name using filter brand_id
while reader.read
case reader.read_string
when 55
-------magic line i couldnt find :)
----------
end
end
magic line must be get brand_name value "Dell" using "55"
Sample xml code ===>> <Brand><Brand_id>55</Brand_id><Brand_name>Dell</
Brand_name></Brand>
