Perl脚本-使用正则表达式的文件关闭

问题描述

大家好！

我有一个文本文件太大，无法逐行处理，但是我需要进行多行匹配.我正在尝试编写脚本以将所需的部分切掉(均为第1部分)，这是到目前为止我所拥有的:

Hello all!

I have a text file that''s too large to be processed without doing it line by line, and yet I need to do multi-line matching. I''m trying to write a script to chop the parts out that I need (both Section 1''s) Here''s what I Have so far:

$insidesection = 0;
while (defined($line = <>))
{
    if($line =~ /Section.*?1/)
    {
        $insidesection = 1;
    }
    elsif($line =~ /Section.*?2)
    {
        $insidesection = 0;
    }
    if ($insidesection = 1)
    {
        print $line;
    }
}

提前谢谢！

仍然似乎不起作用.有人看到我要去哪里了吗?
