Yes, . means any single character in RegEx - except within a character class. Inside character classes the metacharacters lose their meaning (aside from a leading ^ for negation, backslash for escaping, and the ] to end the class). So you don't need to escape the . in that context. Consider this code:
<cfset s = "123.456\?" /> <cfoutput> #s#<br /> #REReplace(s, "[^0-9.]", "", "all")#<br /> #REReplace(s, "[^0-9\.]", "", "all")#<br /> #REReplace(s, "[^0-9\\.]", "", "all")#<br /> #REReplace(s, "[^0-9\\]", "", "all")#<br /> </cfoutput> It will output this: 123.456\? 123.456 123.456 123.456\ 123456\ The backslash to escape the period in the third line (your proposal) is a no-op, because the period doesn't have special meaning to escape from. cheers, barneyb On Thu, May 13, 2010 at 10:41 AM, DURETTE, STEVEN J (ATTASIAIT) <sd1...@att.com> wrote: > > Barney, > > Thanks for correcting my mistake.
