Regex for selecting every white space

What would look regex for selecting every white space? I've tried to do few combinations, including excluding nums, digits etc but to no avail.

\s is the best for a match to a white space character. White space here would be defined as [\t\n\f\r\p{Z}].

Try this link for C++ Regex: http://userguide.icu-project.org/strings/regexp

If the language/environment supports it, you can use the \s modifier.

In perl:

$str = "my string that has spaces"

if($str =~ m/\s/)
{
   #it has a white space character
}

If you cannot use \s directly, you can combine all the items in the list here into one character class. From that link:

If ECMAScript-compliant behavior is specified, \s is equivalent to [\f\n\r\t\v]

What about a simple

\s+

together with a match_all method or option, depending on your language?
