word containing numericals

Question

How can I recognize a word with regex which might contain numerics in it. So I want to capture "string1", "12inches", "log4net". But not 12/11/2011 or 18? Unfortunetly \b[\p{L}\d\p{M}]+\b grabs numericals too.

This:

    Regex regexObj = new Regex(@"\b(?=\S*[a-z])\w+\b", RegexOptions.IgnoreCase);
    Match matchResults = regexObj.Match(subjectString);
    while (matchResults.Success) {
        // matched text: matchResults.Value
        // match start: matchResults.Index
        // match length: matchResults.Length
        matchResults = matchResults.NextMatch();
    } 

comes in mind.

      *           # Between zero and unlimited times, as many times as possible, giving back as needed (greedy)
   [a-z]       # Match a single character in the range between “a” and “z”

\w          # Match a single character that is a “word character” (letters, digits, etc.)
