palabra que contiene números

Question

¿Cómo puedo reconocer una palabra con expresiones regulares que podría contener números en ella? Así que quiero capturar "cadena1", "12 pulgadas", "log4net". Pero no 12/11/2011 o 18? Unfortunetly \b[\p{L}\d\p{M}]+\b agarra números también.

Answer 1

Este:

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(); 
    } 

viene a la mente.

" 
\b   # Assert position at a word boundary 
(?=   # Assert that the regex below can be matched, starting at this position (positive lookahead) 
    \S   # Match a single character that is a “non-whitespace character” 
     *   # 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.) 
    +   # Between one and unlimited times, as many times as possible, giving back as needed (greedy) 
\b   # Assert position at a word boundary 
"

¿Quieres hacer una calcomanía con letras y números en ella? Esto debería funcionar: \b(\w+\d+|\d+\w+)[\w\d]+\b.
