Actually ozo's pattern is even better... I'd just go with that :-)

Yeah, except he may not be searching <i>just </i>the number; he may be searching a string <i>for </i>these numbers...if that's the case, try this:<br />
<br />
(?&lt;!\d)5(2[5-9]|3\d|4[0-2]<wbr />)\d(?!\d)
</div>

(?<!\d)5(2[5-9]|3\d|4[0-2])\d(?!\d)

Regex

A regular expression ("regex") is a sequence of characters that define a search pattern, mainly for use in pattern matching with strings, or string matching, i.e. "find and replace"-like operations. Regular expression processors are found in several search engines, search and replace dialogs of several word processors and text editors, and in the command lines of text processing utilities, such as sed and AWK. Many programming languages provide regular expression capabilities, some built-in, for example Perl, JavaScript, Ruby, AWK, and Tcl, and others via a standard library, for example .NET languages, Java, Python and C++ (since C++11). Most other languages offer regular expressions via a library.
