Short Code Regex

I've written a regex to match a short code in the format similar to:

[playername Le'Veon Bell]

Here is the regex:

\[playername\s+(?<name>[\w \-\'\’]+)\s*\]

I know the regex is struggling with the single quote in the player name. I've tested the regex here and it appears to work, but is not finding the match when I run the code from my web app.

For this example, you don't need to escape -,' symbols which are present inside the character class.

Regex rgx = new Regex(@"\[playername\s+(?<name>[\w '’-]+?)\s*\]");

Based on the information you provided I believe \[playername\s+(?<name>[^]]+?)\s*\] should work.

The only real difference is in the capture group [^]]+ which matches any character that is NOT a ]. This will effectively capture anything after [playername up until the first ]. It'll break if you have nested brackets.

You can use the following regex:

\[playername\s+(?<name>.*?)\s*\]

Without knowing more about your scenario it's kind of difficult to say for sure, but from what you've got, I'd say you should switch to something more like this?

\[playername\s+(?<name>[^\]\s]*)\s+\]

That will match anything that doesn't have a square bracket or space in it, so it seems like what you're actually trying to do. I'd personally be tempted to remove the whitespace conditions, just on the grounds that a name might have a space in it. You could always call whatever your language's version of C#'s string.Trim() is post-facto.

Note, of course, that it isn't exactly the same as what you're doing: you're limiting the characters explicitly. But it looks like you're trying to limit to any text anyway.
