我有一个像
<ns0:Employees xmlns:ns0="http://TestIndexMap.Employees">
<Employee FirstName="FirstName_0" LastName="LastName_1" dept="dept_2" empNumber="1">
<Schedules>
<Schedule Date_join="2008-01-20" Date_end="2008-01-30" />
</Schedules>
</Employee>
<Employee FirstName="FirstName_0" LastName="LastName_1" dept="dept_2" empNumber="2">
<Schedules>
<Schedule Date_join="2008-01-20" Date_end="2008-01-30" />
</Schedules>
</Employee>
<Employee FirstName="FirstName_2" LastName="LastName_1" dept="dept_2" empNumber="2">
<Schedules>
<Schedule Date_join="2007-01-21" Date_end="2007-12-30" />
</Schedules>
</Employee>
<Employee FirstName="FirstName_2" LastName="LastName_1" dept="dept_2" empNumber="2">
<Schedules>
<Schedule Date_join="2007-01-21" Date_end="2007-12-30" />
<Schedule Date_join="2008-06-20" Date_end="2008-01-30" />
</Schedules>
</Employee>
</ns0:Employees>
我想根据 firstname、last name 和 date_join 和 data_end 删除重复项。
请问,有人可以解释如何使用 XSLT 实现这一目标吗?
