Title Test Details Pattern Title
Expression
^\d{9}[\d|X]$
Description
A very simple ISBN validation expression - it just checks for a 10 digit number where the last digit could also be a capital 'X'. Complete specs for ISBN available here: http://www.isbn.org/standards/home/isbn/international/html/usm4.htm. An enhancement would be to allow exactly 3 or 0 hyphens or 3 or 0 spaces, since these are also valid formats.

(http|ftp|https):\/\/[\w\-_]+(\.[\w\-_]+)+([\w\-\.,@?^=%&:/~\+#]*[\w\-\@?^=%&/~\+#])?
Description
*CORRECTED: Again thanks for all the comments below. If you want to include internal domain as well change the partial code (\.[\w-_]+)+ to (\.[\w-_]+)? See the comments below* This is the regular expression I use to add links in my email program. It also ignores those suppose-to-be commas/periods/colons at the end of the URL, like this sentence "check out http://www.yahoo.com/." (the period will be ignored) Note that it requires some modification to match ones that dont start with http.

(\[[Ii][Mm][Gg]\])(\S+?)(\[\/[Ii][Mm][Gg]\])
Description
easy when you want to allow your users to post images, but in a controlled way. I used it like this (in php): $text = preg_replace("/(\[IMG\])(\S+?)(\[\/IMG\])/is", "<a href=\"\\2\" target=\"_blank\"><IMG SRC=\"\\2\" align=\"center\" height=\"100\" border=\"0\"></a>",$text); so whenever they use [img]http://www.foo.com/bleh.jpg[/img] it will be converted to <a href="http://www.foo.com/bleh.jpg" target="_blank"><IMG SRC="http://www.foo.com/bleh.jpg" align="center" height="100" border="0"></a> so you get a 100 pixels high picture, and when they click on it it opens in a new window... (to prevent users from posting huge pictures and stuff)

Description
Incorporated other people's examples; removed extraneous parenthesis on 10/7/04. Currently the SSA site says 772 is the highest AREA number generated (http://www.ssa.gov/employer/highgroup.txt). Old expression was: (^|\s)\d{3}(-?|[\. ])\d{2}\2\d{4}($|\s|[;:,!\.\?]). Looks for either the beginning of a line or whitespace before the beginning of the social security number, then either zero or one hyphen OR one of a period or space, then uses the \3 to reference the value returned in the parenthesis that includes the -?|[\. ] (basically says if the first dash, period, or space is there, then the second one is required; and if the first dash, period, or space is not there, then the second one can't be either), and finally looks for the end of a line, whitespace, or punctuation characters after the social security number.

Secondary range required for some units. City - Proper case city name. State - State abbreviation. All caps zip - zip+4. Can't be all zeroes Abbreviations for secondary units and States are those used by the US Postal Service. http://www.usps.com/ncsc/lookups/usps_abbreviations.html Certain secondary units require a secondary range, see the above link THis RE isn't unbreakable, Probably will allow some false positives but should work for most addresses.

^DOMAIN\\\w+$
Description
In response to a question on the regex list at www.aspadvice.com, this expression should ensure that a login field's username includes a 'DOMAIN\' prefix. The latter part of the expression should probably be limited so that it only allows usernames of appropriate lengths, perhaps 3 to 20 characters (by replacing + with {3,20} for instance).

^(?!\d[1]{2}|[5]{3})([2-9]\d{2})([. -]*)\d{4}$
Description
Validates *usable* US telephone numbers (possibly Canadian and Caribbean Islands as well?) Numbers cannot beginning with zero, one, (any number)11, or 555. It will allow either a hyphen, space or period as a separator. Technically (and contrary to popular belief) most 555- numbers ARE valid numbers [see http://www.nanpa.com/nas/public/form555MasterReport.do?method=display555MasterReport ] but they are unlikely to be used by normal folks. Therefore, excluding them with this regex is useful to prevent bogus/fraudulent telephone numbers in forms. FYI, the fictitious 555- numbers used in the movies and TV are only in the range of 555-0100 through 555-0199. Not very many, huh?

Description
DateTime Validator. This RE validates both dates and/or times patterns. Days in Feb. are also validated for Leap years. Dates: in dd/mm/yyyy or d/m/yy format between 1/1/1600 - 31/12/9999. Leading zeroes are optional. Date separators can be either matching dashes(-), slashes(/) or periods(.) Times: in the hh:MM:ss AM/PM 12 hour format (12:00 AM - 11:59:59 PM) or hh:MM:ss military time format (00:00:00 - 23:59:59). The 12 hour time format: 1) may have a leading zero for the hour. 2) Minutes and seconds are optional for the 12 hour format 3) AM or PM is required and case sensitive. Military time 1) must have a leading zero for all hours less than 10. 2) Minutes are manditory. 3) seconds are optional. Datetimes: combination of the above formats. A date first then a time separated by a space. ex) dd/mm/yyyy hh:MM:ss This RE is an variation of one of my other Datetime (mm/dd/yyyy) validator already in this library http://www.regexlib.com/REDetails.aspx?regexp_id=369, so the same rules for leap year apply. All 4 digit year and all two digit years except 00, which might not be a leap year.

If that is the case for the 4-7 pattern only 0208 or 0207 could be enforced.
