这是你可以尝试的vbscript
Set objFS = CreateObject("Scripting.FileSystemObject")
Set objArgs = WScript.Arguments
Set d = CreateObject("Scripting.Dictionary")
Set e = CreateObject("Scripting.Dictionary")
strFile = objArgs(0)
Set objFile = objFS.OpenTextFile(strFile)
Do Until objFile.AtEndOfStream
strLine=objFile.ReadLine
s = Split(strLine," ")
subject =s(0)
score= Left(s(1),Len(s(1))-1)
studentid=s(2)
If Not d.Exists(subject) Then
d.Add subject, score
e.Add subject, studentid
Else
If score >= d.Item(subject) Then
d.Item(subject) = score
e.Item(subject) = studentid
End If
End If
Loop
j=d.Keys
For Each stritems In j
WScript.Echo "Subject:"&stritems & ", Score: "& d.Item(stritems) & "%, StudentID: " & e.Item(stritems)
Next
输出
C:\test>type file

你需要有一些集合来处理每个主题的总数,这可能会有所帮助
@echo off
set CountXX=1
set CountYY=2
set This=XX
call :Resolve Count%This%
echo %RetVal%
set This=YY
call :Resolve Count%This%
echo %RetVal%
set /a Count%This%=%RetVal% + 2
call :Resolve Count%This%
echo %RetVal%
goto :eof
:Resolve
for /f "delims== tokens=2" %%a in ('set %1') do set retval=%%a
goto :eof
