...To set a bit of variables like "Name" "Bitrate" "Size" and "Download", To print all this information in Batch, like this:
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:

[Download] http://www.bricbrac.free.fr/Music/01___MARILYN_MANSON___ROCK_.MP3
I've tryed "Findstr","Find","SED","GREP","FART" but i can't find the way (A line and chars delimitators) to do it right...
The only i can see to make it possible is this line:
<!-- ================= -->
I can use it like a END-delimitator cause that line marks the end of mp3's to download and to print their info...
Somebody can help me?
thankyou

Answer 1

The Batch file below use the fact that the data you want is located at fixed number of lines below "info mp3 here" line. Also, the data is extracted based on its position in the line. If some data not follow this rule, the program will need a modification.
#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"
Output:

Answer 2

Here's a script that will parse the information you want.
The script takes the name of your HTML file as an argument.
Output is sent to a file with name derived by appending '.parsed' to the input file name.
Comments at the top of the script give a little explanation of the patterns being used to locate the requested information in the HTML file.
Replace the two instances of 'TAB' with tab characters and be sure that you retain the single space before each tab.
#!/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
