我正在尝试将 .html 文件作为一个大长字符串打开.这就是我所拥有的:
I'm trying to open an .html file as one big long string. This is what I've got:
open(FILE, 'index.html') or die "Can't read file 'filename' [$!] "; $document = <FILE>; close (FILE); print $document;导致:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN但是,我希望结果如下:
However, I want the result to look like:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "www.w3/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">这样我可以更轻松地搜索整个文档.
This way I can search the entire document more easily.
推荐答案添加:
local $/;在从文件句柄读取之前.请参阅如何我可以一次读取整个文件吗? 或
before reading from the file handle. See How can I read in an entire file all at once?, or
$ perldoc -q "entire file"参见与文件句柄相关的变量在 perldoc perlvar 和 perldoc -f local.
顺便说一句,如果你能把你的脚本放在服务器上,你就可以拥有你想要的所有模块.请参阅如何保持我的自己的模块/库目录?.
Incidentally, if you can put your script on the server, you can have all the modules you want. See How do I keep my own module/library directory?.
此外,Path::Class::File 允许您slurp 和 spew.
In addition, Path::Class::File allows you to slurp and spew.
Path::Tiny 提供了更方便的方法,例如 slurp、slurp_raw、slurp_utf8 以及他们的 spew 同行.
Path::Tiny gives even more convenience methods such as slurp, slurp_raw, slurp_utf8 as well as their spew counterparts.
