使用XSLD从XML转换为CSV

Question

我想知道您是否可以使用XSL导出到CSV到特定列。例如，在此示例中，某些员工缺少电子邮件，电话号码或部门。但是我希望结果是，如果缺少元素，则将其留空。

 <Employees>
   <Employee>
     <EmployeeID>1</EmployeeID>
     <EmpName>Homer Simpson</EmpName>
     <Department>IT1</Department>
     <PhNo>9111111111</PhNo>
     <Email>Homer.Simpson@gmail.com</Email>
     <Salary>99999</Salary>
   </Employee>
   <Employee>
     <EmployeeID>2</EmployeeID>
     <EmpName>John Smith</EmpName>
     <Department>IT2</Department>
     <PhNo>9222222222</PhNo>
     <Email>smith@gmail.com</Email>
     <Salary>99999</Salary>
   </Employee>
   <Employee>
     <EmployeeID>3</EmployeeID>
     <EmpName>Marge Simpson</EmpName>
     <Department>IT3</Department>
     <Salary>99999</Salary>
   </Employee>
   <Employee>
     <EmployeeID>4</EmployeeID>
     <EmpName>Bruce Wayne</EmpName>
     <Department>IT4</Department>
     <Email>batman@gmail.com</Email>
   </Employee>
 </Employees>
