[已解决]批处理怎样提取合并多行文本？

noe

有文本内容结构类似如下：
Year: 2011
Month: 3
Version: 201103A
STUDENT
Number: 1
Gender: male
Class: A
Advance: yes
STUDENT
Number: 5
Gender: female
Class: A
Advance: yes
Special: A
STUDENT
Number: 16
Gender: male
Class: B
Advance: no
Special: 9
STUDENT
Number: 17
Gender: male
Class: A
Advance: yes
END

每个STUDENT段包含Number， Gender， Class， Advance， Special这些行。其中前面4个必有，Special这行可能没有。
现希望经过操作后，将每个STUDENT信息合并成一行，如下
Number: 1, Gender: male, Class: A, Advance: yes
Number: 5, Gender: female, Class: A, Advance: yes, Special: A
Number: 16, Gender: male, Class: B, Advance: no, Special: 9
Number: 17, Gender: male, Class: A, Advance: yes

求处理方法。能纯批处理最好，不能实现的话使用第三方命令行程序亦可。
感谢。

Hello123World

假设多行文本的文件名为test.txt，
将批处理放在和test.txt同一个文件夹。

1. @echo off
   
2. (for /f "tokens=*" %%i in (test.txt) do (
   
3.         if /i %%i==student (echo %%i) else (
   
4.                 set /p =%%i <nul
   
5.         )
   
6. ))>test1.txt
   
7. 
   
8. pause>nul

Number: 5 Gender: female Class: A Advance: yes Special: A STUDENT
Number: 16 Gender: male Class: B Advance: no Special: 9 STUDENT

输出结果与期望的略有不同，但这样的结果已经能让我满意。感谢。
