Regex vs, versus, vs., v. matching in lines for C# code

Question

I need to write a regex that matches the word versus, verse, vs., v., v but v should not be jumbled in words.

@"\b((.*?)" + Regex.Unescape(xz) + @"[.,:/s]?)\b", RegexOptions.IgnoreCase))

Here I'll pass the array and test it.

Answer 1

This will get you close:

\b(?:(?:vers(?:e|us)|v)\b|vs\.|v\.)

One difficulty is in word boundaries vs. (heh) words that end in a period. See Regex using word boundary but word ends with a . (period) for other options.

Note that "verse" can also mean "poetry" so there could be false positives.
