如何使用XSLT比较两个XML节点

如何解决如何使用XSLT比较两个XML节点

**我需要比较两个合并的XML，但是下面的代码不起作用。 **

XML：

<File>
 <wd:Report_Data xmlns:wd="urn:com.workday.report/CR">
   <wd:Report_Entry>
      <wd:Worker>Bal Shil (1234)</wd:Worker>
      <wd:Employee_ID>1234</wd:Employee_ID>
      <wd:User_Name>bal</wd:User_Name>
     <wd:ReportprimaryWorkEmail>bal.shil@gmail.com</wd:ReportprimaryWorkEmail>
      <wd:Security_Groups>
         <wd:Security_Group_Name>SG Group 1</wd:Security_Group_Name>
         <wd:Security_Group_Type>UBSG Group</wd:Security_Group_Type>
       <wd:Reference_ID_Type_XML_Name>Group_ID</wd:Reference_ID_Type_XML_Name>
         <wd:SG_Reference_ID>SG_Learning</wd:SG_Reference_ID>
      </wd:Security_Groups>
      <wd:Flag>0</wd:Flag>
      <wd:Company>AB</wd:Company>
   </wd:Report_Entry>
   <wd:Report_Entry>
 </wd:Report_Data>
   <wd:Report_Entry>
      <wd:Worker>Har Sneh(2345)</wd:Worker>
      <wd:Employee_ID>2345</wd:Employee_ID>
      <wd:User_Name>har</wd:User_Name>
     <wd:ReportprimaryWorkEmail>har.sneh@gmail.com</wd:ReportprimaryWorkEmail>
      <wd:Security_Groups>
         <wd:Security_Group_Name>SG Group 1</wd:Security_Group_Name>
         <wd:Security_Group_Type>UBSG Group</wd:Security_Group_Type>
         <wd:Reference_ID_Type_XML_Name>Group_ID</wd:Reference_ID_Type_XML_Name>
         <wd:SG_Reference_ID>SG_Learning</wd:SG_Reference_ID>
      </wd:Security_Groups>
       <wd:Flag>1</wd:Flag>
      <wd:Company>IT AB</wd:Company>
   </wd:Report_Entry>
 </wd:Report_Data>
 <InputFile>
     <Record>
       <primary_email_address>sun.tan@hotmail.com</primary_email_address>
       <preferred_last_name/>
       <preferred_first_name/>
     </Record>
     <Record>
       <primary_email_address>bal.shil@gmail.com</primary_email_address>
       <preferred_last_name/>
       <preferred_first_name/>
     </Record>
     <Record>
       <primary_email_address>Ami.anu@note.com</primary_email_address>
       <preferred_last_name/>
       <preferred_first_name/>
     </Record>
     <Record>
       <primary_email_address>har.sneh@gmail.com</primary_email_address>
       <preferred_last_name/>
       <preferred_first_name/>
     </Record>
 </InputFile>
</File>

我正在尝试将InputFile primary_email_address与Report_Data ReportprimaryWorkEmail进行比较，但是在XSLT以下代码始终与ReportprimaryWorkEmail的第一个Report_Data条目进行比较

XSLT

请帮助我与Report_Data的所有节点进行比较

*我需要将Report_Data节点与InputFile节点进行比较，并在以下情况下获取输出：------

场景1 [操作：添加]：如果ReportprimaryWorkEmail（在Report_Data节点中）存在InputFile节点primary_email_address，且Flag为0。||
场景2 [操作：跳过]：如果ReportprimaryWorkEmail（在Report_Data节点中）存在InputFile节点primary_email_address，且Flag为1。||
方案3 [操作：无效]：如果InputprimaryWorkEmail中不存在InputFile节点primary_email_address（在Report_Data节点中）*

所需的输出

<EmpRecord>
      <Email>sun.tan@hotmail.com</Email>
       <Operation>Invalid </Operation>
       <preferred_last_name/>
