I need to extract words that contain digits.

ex:-

Input - 3909B Witmer Road. Niagara Falls. NY 14305

Output - 3909B and 14305

Use this regex:

\w*\d\w*

The basic expression should be:

  1. (?<=^| )(?=[^ ]*\d)[^ ]+

    • OR -

  2. (\w*\d[\w\d]+)

And to use it in C#:

var matches = Regex.Matches(input, @"(\w*\d[\w\d]+)");

foreach (Match match in matches){
       var word = match.Value; 
}

...

var matches = Regex.Matches(input, @"(?<=^| )(?=[^ ]*\d)[^ ]+");

foreach (Match match in matches){
    var word = match.Value; 
}

You mean you want to extract number-ey words:

var matches = Regex.Matches(input, @"\d\w*");

foreach (Match match in matches) {
    var numWord = match.Value;    // 3909B, etc.
}

  • @Joseph: Correct. Whether the OP wants that or not is open to interpretation ;-) – Cameron Jan 26 '12 at 05:17
  • Thank you very much it works.. yeah for that we have to add +\w in the front. correct regex would be @"\w+\d+\w*" – Dan Jan 26 '12 at 05:27

This is the simplest regex I could come up with that can handle words that have a mixture of letters and digits:

(\w*\d[\w\d]+)

So this will match your desired words, plus it would match 'abc123xyz'. Try it yourself.
