RegEx for range search

ravilobo · Post by **ravilobo** » Fri May 01, 2009 3:54 pm

Is it possible to have RegEx for a range? For e.g. how to write a RegEx that searches numbers falling between 50 and 75?

In the general case, no. Regular expressions can't do arithmetic. But in your specific case it's not too hard:
\<([56][0-9]|7[0-5])\>

This assumes you are using Posix regular expression syntax:

Configure | Preferences | Editor

[X] Use POSIX regular expression syntax
