上面显示的字符串是为我的供应商编写的应用程序定制的 XML 文件的一部分。我可以访问 XML 但我不知道如何解码 file.Is 节点中包含的此类字符串 有一种方法可以对其进行解码 and/or 以了解应用了哪种编码是吗?

它是 64 进制数。 在 unix 上,您可以使用 base64 解码。 在 Windows,您可能需要编写脚本。

use strict;
use warnings;
use MIME::Base64 qw ( decode_base64 );

my $stuff = <DATA>;
open( my $output, ">", "something.out" );

#print decode_base64($stuff);
foreach ( split( //, decode_base64($stuff) ) ) {
    printf( "%02x ", ord($_) );
    print "\n" if $_ eq "\n";
}

根据您提供的内容,它解码为某种二进制数据类型。我不知道 that 应该是什么文件格式。

以字节模式开头:

1f 8b 08 00

其中指的是:http://www.garykessler.net/library/file_sigs.html

表示它是一个 gzip 压缩文件。

简单的方法就是将 something.out 另存为 something.gz 并使用您拥有的任何 gzip 工具。 (你也许可以用 IO::Uncompress::Gunzip 之类的东西来 perl 它)
