Find words with specified first letter (Regex)

Question

I need regex to find words starting, for example, whith letters "B" or "b". In sentence Bword abword bword I need to find Bword and bword. My curresnt regex is: [Bb]\w+ (first character is space), but it doesn't find Bword.

Thanks in advance.

Answer 1

Try using following regex: (?i)\bB\w*\b

It means:

1. (?i) - turn on ignore case option
2. \b - first or last character in a word
3. B
4. \w* - Alphanumeric, any number of repetitions
5. \b - first or last character in a word

So it will find Bword and bword.
