View 2 Replies View RelatedRegular Expression :: Validate Date-time Field In European D/m/y H:m:s Format
Jul 23, 2005I 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.

View 2 Replies View RelatedRegular Expression To Test The Validity Of An Input Date?
Jan 6, 2011I have the following regular expression to test the validity of an input date:
([0-9][0-9]|[0-9])[s/-]([0-9][0-9]|[0-9])[s/-]([0-9][0-9][0-9][0-9]|[0-9][0-9])
It should allow 1 or two digits for the day of the month, then a separating character (" ", "/" or "-"), then 1 or two digits for the month, then 2 or 4 digits for the year.
Unfortunately it will accept anything above 2 digits for the year, which I understand why is happening but don't know how to fix!

Regular Expression To Get The File Name From A URL?
Feb 5, 2009regular 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, 2006I need a regular expression that will validate a double quote comma

restriction.

Regular Expression To Exclude Lines?
Jul 20, 2005All 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

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.
