正则表达式分割字母

Question

Using .net, what is a regular expression to split on, pulling out groups of letters?

I tried @"[a-zA-Z]*", then regex.Split... as an example, but I'm totally lost.

Thanks

Answer 1

The * doesn't require at least one character to match. Try

@"[a-zA-Z]+"

instead.

Actually, if you want the letters themselves, don't use Regex.Split , use Regex.Match or Regex.Matches . The Split version will capture what's between the strings of letters.

Answer 2

Not exactly what you asked for, but, just in case you already know the kind of caracters that might separate the words you could simply use String.Split .

Of course this is only if you there are a few specific characters separating the words, such as spaces or commas, like "word,word.word word" but not if you want to pick up groups of letters in the middle of a bunch of other stuff like in "lk234lkv234.2@#$dfff(*"

I know I'm going a bit away from the original question, but still you might find this useful
