在 Perl 中，如何将整个文件读入字符串? [英] In Perl, how can I read an entire file into a string?
问题描述
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" "http://www.w3.org/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.
