As I understand you need to store in xml the company list from your database.
Try this:

            while (rs.next())
            {
                Element child1 = doc.createElement("Company");
                child1.setAttributeNS(xlink, "xlink:type", rs.getString (1));
                child1.setAttributeNS(xlink, "xlink:show", "  ");
                child.appendChild(child1);   
            }

Though I don’t quite understand your sql query

select CId from company

Is company a table or some other select query?
