关于perl的问题
现有a文件
1
00:00:16,000 --> 00:00:19,000
When I was 10 years old,
2
00:00:19,000 --> 00:00:22,000
a cousin of mine took me on a tour of his medical school.
3
00:00:22,000 --> 00:00:24,000
And as a special treat
4
00:00:24,000 --> 00:00:26,000
he took me to the pathology lab
5
00:00:26,000 --> 00:00:28,000
and took a real human brain
6
00:00:28,000 --> 00:00:30,000
out of the jar
7
00:00:30,000 --> 00:00:32,000
and placed it in my hands.
b文件
1
00:00:16,000 --> 00:00:19,000
我十岁的时候
2
00:00:19,000 --> 00:00:22,000
我的一个表兄带我参观了他上的医学院
3
00:00:22,000 --> 00:00:24,000
作为一次特别优待
4
00:00:24,000 --> 00:00:26,000
他带我去了病理学实验室
5
00:00:26,000 --> 00:00:28,000
拿出一个真正的人脑
8
00:00:28,000 --> 00:00:30,000
从一个罐子里
9
00:00:30,000 --> 00:00:32,000
把它放在了我手里
然后将a文件以句号为分割,时间轴合并,提取出了
c文件
1
00:00:16,000 --> 00:00:22,000?1
When I was 10 years old,
a cousin of mine took me on a tour of his medical school.
2
00:00:22,000 --> 00:00:32,000
And as a special treat
he took me to the pathology lab

怎么从b文件中提取出与c文件对应的中文文本d文件呢,时间轴以英文a文件的为依据如下：
d文件
1
00:00:16,000 --> 00:00:22,000?1
我十岁的时候,
我的一个表兄带我参观了他上的医学院.
2
00:00:22,000 --> 00:00:32,000
作为一次特别优待,
他带我去了病理学实验室,
拿出一个真正的人脑,
从一个罐子里,
把它放在了我手里.
暂时先这么多分,好的话,一定会再加的,

正则表达式是 Perl 语言的一大特色,也是 Perl 程序中的一点难点,不过如果能够很好的掌握他,就可以轻易地用正则表达式来完成字符串处理的任务,当然在设计中就更能得心应手了.
