使用xslt检查并替换xml中的值

Question

我需要将以下xml转换为包含条件的xsl代码，如果此人的部门标签为IT1，则该值应显示为“ bonus +”薪水标签值。请找到我尝试过的xsl代码，但条件不起作用。请帮助

xml code:
<?xml version="1.0" encoding="utf-8"?>
 <Employees>
   <Employee>
     <EmployeeID>1</EmployeeID>
     <EmpName>Tarun1 Chatterjee1</EmpName>
      <contact>
        <PhNo>9111111111</PhNo>
        <Email>tarun2.chatterjee2@gmail.com</Email>
      </contact>
      <Division>
        <Department>IT1</Department>
        <Salary>10000</Salary>
      </Division>
   </Employee>
   <Employee>
     <EmployeeID>2</EmployeeID>
     <EmpName>Tarun2 Chatterjee2</EmpName>
     <contact>
        <PhNo>9111111111</PhNo>
        <Email>tarun2.chatterjee2@gmail.com</Email>
      </contact>
      <Division>
       <Department>IT2</Department>
       <Salary>20000</Salary>
      </Division>
   </Employee>
   <Employee>
     <EmployeeID>3</EmployeeID>
     <EmpName>Tarun3 Chatterjee3</EmpName>
     <contact>
        <PhNo>9111111111</PhNo>
        <Email>tarun2.chatterjee2@gmail.com</Email>
      </contact>
      <Division>
       <Department>IT2</Department>
       <Salary>20000</Salary>
      </Division>
  </Employees>

Expected output is 
1;Tarun1 Chatterjee1;9111111111;tarun2.chatterjee2@gmail.com;bonus+10000
2;Tarun2 Chatterjee2;9111111111;tarun2.chatterjee2@gmail.com;0+20000
3;Tarun3 Chatterjee3;9111111111;tarun2.chatterjee2@gmail.com;0+20000

xsl代码：          

<xsl:template match ="/">
     <xsl:for-each select="Employees/Employee">

         <xsl:value-of select="EmployeeID" />
         <xsl:text>;</xsl:text>
