Regular Expression :: Validate US And Canadian Postal Codes?

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,alpha number,alpha,number.

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}/)

Regular Expression To Validate Township

Mar 31, 2009

I'm trying to validate data in a textbox for township (usually written as 12N or 23S for Township 12 North or Township 23 South). In Utah the townships range from 01N to 15N, and 01S to 44S. The expression "/[0-9][0-4][ns]/i" will allow 01n (or s) through 94n (or s). If I change it to "/[0-4][0-4][ns]/i" to limit it to 44n (or s), I then am not allowing for 05, 06, 07, 08, and 09. I hope the above is not too confusing. I'm just starting to work with regular expressions.

Regular Expression Validate Email Address

Jul 23, 2005

/^[a-zA-Z0-9_-]+([.][a-zA-Z0-9_-]+)*@[a-zA-Z_-]+([.][a-zA-Z0-9_-]+)*$/

I'm using this to try to validate a small subset of the valid e-mail
addresses allowed by the relevant RFC (alphanumerics, underscores, and
dashes). I've tested it and it seems to work....

Regular Expression :: Validate Numbers Separated By Period (.)

Dec 19, 2005

I need a regular expression to validate a string which consists of numbers, seprated by a period. For example: 123.456.7890.123 or

543245634.564362454.543543523.43532543

Basically, its a set of any amount of numbers, seperated by a period, ocurring any number of times. Now this is my first time dealving into regular expressions, and after reading some tutorials i came up with this:

/+((+d).)/

Would this evaluate correctly?

Regular Expression :: Validate Date-time Field In European D/m/y H:m:s Format

Jul 23, 2005

I have the following regular expression to validate a date-time field
in European or d/m/y h:m:s format.

^((((31/(0?[13578]|1[02]))|((29|30)/(0?[1,3-9]|1[0-2])))/(1[6-9]|[2-9]d)?d{2})|(29/0?2/(((1[6-9]|[2-9]d)?(0[48]|[2468][048]|[13579][26])|((16|[2468][048]|[3579][26])00))))|(0?[1-9]|1d|2[0-8])/((0?[1-9])|(1[0-2]))/((1[6-9]|[2-9]d)?d{2}))
(20|21|22|23|[0-1]?d):[0-5]?d:[0-5]?d$

I wish to ammend it so that the time or h:m:s part is validated only if
supplied (i.e. I wish to make the time part optional). At present if a
time is not supplied the validation fails. I gather that the following
part of the above expression

(20|21|22|23|[0-1]?d):[0-5]?d:[0-5]?d$

validates the time, however I don't know the syntax to make it
optional.

?: In Regular Expression

Feb 21, 2006

I have seen lot of reg. expession with ?:
For dummy eg
(((XXX)ddd)ff)

The above expression is modified as
(?:(?:(XXX)ddd)ff)

Although both the above expr. gives same result. (RegExp.match() gives
same o/p), most of the places , i have seen second option.

Yes, but different matches r shown (using RegExp.exec())

Is the second expr. most efficient or in particular scenarios?

Any comments???

Regular Expression To Get The File Name From A URL?

Feb 5, 2009

regular express to get the file name from a URL?

It has to be flexible in that the extension can be either 4, 5, or 6 chars (.php, .html, .shtml for example) and needs to cater for and whether querystring parameters exist too.

So, both

[URL]

and

[URL]

The regex should return newthread for both.

Comma Delimited Regular Expression

Dec 7, 2006

I need a regular expression that will validate a double quote comma
delimited list where the odd entries are numeric and the even are
alphabetical. Each pair must also be on a separate line. For example:

"1","Peter"
"2","Paul"
"3","Mary"

I've used the following expression to validate comma delimited lists, but
without the double quotes, numeric/alpha pairing and line return
restriction.

^([A-Za-z0-9]?)+([,]s?([A-Za-z0-9]?)+)*$

Regular Expression To Match Any Spaces

Oct 9, 2007

Normally I can write regular expressions decently well but for some
reason I am having trouble getting this to work. I am validating form
data and need to throw an error if there are ANY spaces in the field.
abc123 is fine, abc 123 is not. Any character is fine, just not a
space.

Regular Expression To Exclude Lines?

Jul 20, 2005

All I'm trying to do is delete the lines which don't contain a particular
string. Actually a filter to edit a log file. I can find and replace a thing
with null, but can't figure out how to find the lines which do not contain
the thing.

Going further, I want to generalize and use a JavaScript variable containing
the decision string, but first I need to worry about the not-within-a-line
problem.
