...要设置一些变量，如“名称”“比特率”“大小”和“下载”，要以批量打印所有这些信息，如下所示：
1st result:
[Name] Marilyn Manson - Tainted Love ( Manson Remix) mp3
[Info] Bitrate: 256 kbps. Length: 3:21. Size: 6.13 mb.
[Download] http://rockass.free.fr/video/Marilyn Manson - Taited Love.mp3
2nd result:

[Info] NO INFO.
[Download] http://spaz.mindstab.net/djspaz_-_grow_up_and_blow_the_great_big_white_nietzche.mp3
3rd result:

我尝试过“Findstr”，“Find”，“SED”，“GREP”，“FART”，但我找不到方法（A行和字符分隔符）来做正确的事......
我唯一可以看到的就是这条线：
<!-- ================= -->
我可以像END-delimitator一样使用它，因为该行标记了MP3的下载和打印信息......
有人可以帮助我吗？

下面的批处理文件使用了您想要的数据位于“info mp3 here”行下方固定行数的事实。此外，数据是根据其在行中的位置提取的。如果某些数据不遵循此规则，则程序将需要修改。
@echo off
setlocal EnableDelayedExpansion
findstr /N /C:"info mp3 here" %1 > "%~N1.tmp"
set lastLine=-1
(for /F "usebackq delims=:" %%a in ("%~N1.tmp") do (
set /A skip=%%a-lastLine
for /L %%i in (1,1,!skip!) do set /P info=
set /P =& set /P name=
for /L %%i in (1,1,4) do set /P download=
set "name=!name:*<b>=!
for /F "delims=<" %%n in ("!name!") do echo [Name] %%n
set "info=!info:<br />= !"
set "info=!info:</div>=!"
set bitrate=
set lenght=
set size=
set value=
for %%t in (!info!) do (
if not defined value (
set value=%%t
) else (
if %%t equ kbps (
set "bitrate=Bitrate: !value! kbps. "
set value=
) else if %%t equ mb (
set "size=Size: !value! mb."
set value=
) else (
set "lenght=Lenght: !value!. "
set value=%%t
)
)
)
if defined value (
set "lenght=Lenght: !value!. "
)
set info=!bitrate!!lenght!!size!
if not defined info set info=NO INFO.
echo [Info] !info!
set "download=!download:"=$!"
for /F "tokens=4 delims=$" %%d in ("!download!") do echo [Download] %%d
set /A lastline=%%a+6
)) < %1
del "%~N1.tmp"
输出：

这是一个将解析您想要的信息的脚本。
该脚本将HTML文件的名称作为参数。
通过将“.parsed”附加到输入文件名，将输出发送到名称派生的文件。
脚本顶部的注释给出了用于在HTML文件中查找所请求信息的模式的一些解释。
使用制表符替换“TAB”的两个实例，并确保在每个制表符之前保留单个空格。
#!/bin/bash
# Parse HTML with sed, suppressing all unwanted lines
# "Info" lines all start with a number (ignoring whitespace)
# Bitrate and file size can be identified by looking for
# the unit (kbps, mb) immediately following the numeric data
# Length is identified by the colon in the middle of numeric data
# File names are delimited by <b> and </b>
# Lines with the URL all contain Download</a>
# The </a> isn't necessary, but I thought it would be safer to
# include it since one could imagine "Download" appearing in a file name
# Pipe output to Awk for reordering of the parsed lines
# and addition of "NO INFO" lines where necessary
sed -n '
/^[ TAB]*[0-9]/ {
s/^[ TAB]*/[Info] /
s/\([0-9]*:[0-9]*\)[^0-9]*/Length: \1. /
s/\([0-9\.]* .bps\)[^0-9L]*/Bitrate: \1. /
s/\([0-9\.]* .b\)[^p][^0-9LB]*/Size: \1. /
p
}
/<b>/ {
s|</b>.*||
s|.*<b>\(.*\)|[Name] \1|
p
}
\|Download</a>| {
s/^.*\(http:[^"]*\).*/[Download] \1/
p
}' $1 | awk 'BEGIN { no_info = "[INFO] NO INFO.";
info = no_info }
{ if ($1 == "[Name]") name = $0;
else if ($1 == "[Info]") info = $0;
else {
printf("%s\n%s\n%s\n\n", name, info, $0);
info = no_info
} }' > $1.parsed
exit 0
