Hi there, I want to use regex to parse a m3u list. Let's suppose we have this m3u item:
#EXTINF:-1, tvg-name="THE NAME" tvg-logo="THE LOGO" group-title="THE TITLE",THE ITEM
https://www.SampleSite.com


I want to extract THE NAME,THE LOGO, THE TITLE, THE ITEM, and the URL line.

What I have tried:

I've used this pattern and it can extract all parts except "THE ITEM" that follows after a comma(,)
C#
string pattern = @"\btvg-name=""([^""]+)"".tvg-logo=""([^""]+)"".group-title=""([^""]+)"".*(,?\w).\n*(https?\S+)"

Try this:
C#
\btvg-name="([^"]+)".tvg-logo="([^"]+)".group-title="([^"]+)",(.*?)\n*(https?\S+)


If you are going to work with regexes, get a copy of Expresso[^] - it's free, and it examines and generates Regular expressions.

Thanks! That works. And about Expresso[^], I've downloaded it but I can't exactly figure out how to use it.

See the "Help" menu - it covers most of it.
Just a few interesting links to help building and debugging RegEx.
Here is a link to RegEx documentation:
perlre - perldoc.perl.org[^]
Here is links to tools to help build RegEx and debug them:
.NET Regex Tester - Regex Storm[^]
Expresso Regular Expression Tool[^]
RegExr: Learn, Build, & Test RegEx[^]
Online regex tester and debugger: PHP, PCRE, Python, Golang and JavaScript[^]
This one show you the RegEx as a nice graph which is really helpful to understand what is doing a RegEx: Debuggex: Online visual regex tester. JavaScript, Python, and PCRE.[^]
This site also show the Regex in a nice graph but can't test what match the RegEx: Regexper[^]
