Capture text from changeable source (regex)

[Alir3z4]

Actually i couldn't find suitable title than this!
Okay i have a QTextBrowser which get output from QProcess and the output printed-out from "axel" downloader.
What i want to do is get just proggress text which is like [ #%]
the output is here

[  0%]   [0                                                 ] [ 275.9KB/s] [ 2h06]
[  22%] [0                                                 ] [ 276.4KB/s] [ 2h06]
[  34%] [0                                                 ] [ 276.9KB/s] [ 2h06]
[  43%] [0                                                 ] [ 278.9KB/s] [ 2h05]

[  0%]   [0                                                 ] [ 275.9KB/s] [ 2h06]
[  22%] [0                                                 ] [ 276.4KB/s] [ 2h06]
[  34%] [0                                                 ] [ 276.9KB/s] [ 2h06]
[  43%] [0                                                 ] [ 278.9KB/s] [ 2h05]

To copy to clipboard, switch view to plain text mode 

in try some regex pattern which i was failed in them.

• \\d%
• \\d{1,3}%

so if i can get the progress text then i can reach to download speed, remaining time and others i think.

i just want to show the download progress on the gui, of course i can calculate the download progress by orignal file size and downloaded size, but get help from regex seems more clever

Please read the documentation to QRegExp. As a short kick-off

QRegExp rx("\\[[ ]*([1-9]{1,2})\\%\\]");

QRegExp rx("\\[[ ]*([1-9]{1,2})\\%\\]");

To copy to clipboard, switch view to plain text mode

Despite that yours didn't smash any stone for me :|, Well thanks who move this thread to Newbie sub-forum because it remind me that don't hack stupid soft sands when you can use API
i just found axel's API.

Using the API of your downloader is surely the best way to go. As to my suggestion:

QString test = "[ 34%] [0 ] [ 276.9KB/s] [ 2h06]";
QRegExp rx("\\[[ ]*([1-9]{1,2})\\%\\]");
rx.indexIn(test);
qWarning() << rx.capturedTexts();

QString test = "[ 34%] [0 ] [ 276.9KB/s] [ 2h06]";
QRegExp rx("\\[[ ]*([1-9]{1,2})\\%\\]");
rx.indexIn(test);
qWarning() << rx.capturedTexts();

To copy to clipboard, switch view to plain text mode 

returns 34. The percentage you wanted... (At least I understand your post so.)
