Does anyone know of a regualr expression to validate US and Canadian Postal
Codes?
I want to be able to accept ##### or #####-#### or Canadian A#A #A# that is
alpha,number,al pha number,alpha,nu mber.
I am new to regular expressions. The US 5 digit part is easy, but I get
stuck after that.
var pattern = new RegExp(/\\d{5}/)
Any ideas? Thanks everybody.

Firstly there are two ways of creating a RegExp, and your example mixes
the two up.
The first is:-
r=new RegExp("Pattern ", "Optional Switches g and i");
The second is a Regular Expression Literal
r=/Pattern/Optional Switches;
Note that with the first the Pattern must be in a string, and needs to
use escapes for backslashes \\
In terms of your requirement, I am sure others will have better
suggestions but you could try the following:-
var r=/^(\d{5}|\d{5}-\d{4}|[A-Za-z]\d[A-Za-z] \d[A-Za-z]\d)$/;
Same as:-
var r=new RegExp("^(\\d{5 }|\\d{5}-\\d{4}|[A-Za-z]\\d[A-Za-z]
\\d[A-Za-z]\\d)$");
Note that the ^ will prohibit any leading characters, and $ will
prohibit any trailing characters, the | is an alternative marker, and I
assume only one space between A#A #A#
Hope this helps.

Beautiful. Thanks for your help.

Only slightly improved:
/^(\d{5}(-\d{4})?|[a-z]\d[a-z] \d[a-z]\d)$/i
The space prevents the Canadian postal code pattern from being reduced.

Rather than using one catch-all expression, it may be better practice to
validate postcodes against the specified region.

Hi,
I am replaceing a big string using different regular expressions (see
some example at the end of the message). The problem is whenever I
apply a "replace" it makes a new copy of string and I want to avoid
that. My question here is if there is a way to pass either a memory
stream or array of "find", "replace" expressions or any other way to
avoid multiple copies of a string.
Any help will be highly appreciated

I have a regular expression (^(.+)(?=\s*).*\1 ) that results in
matches. I would like to get what the actual regular expression is.
In other words, when I apply ^(.+)(?=\s*).*\1 to " HEART (CONDUCTION
DEFECT) 37.33/2 HEART (CONDUCTION DEFECT) WITH
CATHETER 37.34/2 " the expression is "HEART (CONDUCTION DEFECT)". How
do I gain access to the expression (not the matches) at runtime?
Thanks,
