(?=(/content/xxx/(.*)/(.*)/(.*)/(.*)/*))(?=(^(?:(?!sample1|sample2).)*).*)
This is my regex pattern to limit my visibility of templates under some path and avoid being created under specific folders.
Could anyone figure out any issue or suggest some other ways?
You may use
^/content/([^/]*)/([^/]*)/([^/]*)/(?![^/]*/(?:sample1|sample2))([^/]*)
See the regex demo
Details:
^ - start of string
/content/ - a literal substring
([^/]*)/ - 0+ chars other than / and a /
([^/]*)/([^/]*)/ - 2 previous subpatterns on end
(?![^/]*/(?:sample1|sample2)) - a negative lookahead that fails the match if there are any 0+ chars other than /, then / and either sample1 or sample2 immediately to the right of the current location
([^/]*) - 0+ chars other than /
Note that if you are not using submatches, the pattern can be shortened to
^/content/(?:[^/]*/){3}(?![^/]*/(?:sample1|sample2))[^/]*

Using Regex, I want to match any URL that includes the /it-jobs/ but must have something after the final /.
To be a match the URL must have /it-jobs/ + characters after the trailing / otherwise it should not match. Please refer to below example.
Example: www.website.com/it-jobs/ - is not a match
www.website.com/it-jobs/java-developer - is a match
www.website.com/it-jobs/php - is a match
www.website.com/it-jobs/angular-developer - is a match
You can use
/it-jobs/[^/\s]+$
To match the whole string, add .* at the pattern start:
.*/it-jobs/[^/\s]+$
See the regex demo.
Details:
.* - zero or more chars other than line break chars as many as possible
/it-jobs/ - a literal string
[^/\s]+ - any one or more chars other than / and whitespaces
$ - end of string.
I have this regular expression:
/^www\.example\.(com|co(\.(in|uk))?|net|us|me)\/?(.*)?[^\/]$/g
It matches:
www.example.com/example1/something
But doesn't match
www.example.com/example1/something/
But the problem is that, it matches: I do not want it to match:
www.example.com/example1/something/otherstuff
I just want it to stop when a slash is enountered after "something". If there is no slash after "something", it should continue matching any character, except line breaks.
I am a new learner for regex. So, I get confused easily with those characters
You may use this regex:
^www\.example\.(?:com|co(?:\.(?:in|uk))?|net|us|me)(?:\/[^\/]+){2}$
RegEx Demo
This will match following URL:
www.example.co.uk/example1/something
You can use
^www\.example\.(?:com|co(?:\.(?:in|uk))?|net|us|me)\/([^\/]+)\/([^\/]+)$
See the regex demo
The (.*)? part in your pattern matches any zero or more chars, so it won't stop even after encountering two slashes. The \/([^\/]+)\/([^\/]+) part in the new pattern will match two parts after slash, and capture each part into a separate group (in case you need to access those values).
Details:
^ - start of string
www\.example\. - www.example. string
(?:com|co(?:\.(?:in|uk))?|net|us|me) - com, co.in, co.uk, co, net, us, me strings
\/ - a / char
([^\/]+) - Group 1: one or more chars other than /
\/ - a / char
([^\/]+) - Group 2: one or more chars other than /
$ - end of string.
I have the following regex:
(^|^[^:]+:\/\/|[^\.]+\.)hello\.net
Which seems to work fors most cases such as these:
http://hello.net
https://hello.net
http://www.hello.net
https://www.hello.net
http://domain.hello.net
https://solutions.hello.net
hello.net
www.hello.net
However it still matches this which it should not:
hello.net.domain.com
You can see it here:
https://regex101.com/r/fBH112/1
I am basically trying to check if a url is part of hello.net. so hello.net and any subdomains such as sub.hello.net should all match.
it should also match hello.net/bye. So anything after hello.net is irrelevant.
You may fix your pattern by adding (?:\/.*)?$ at the end:
(^|^[^:]+:\/\/|[^.]+\.)hello\.net(?:\/.*)?$
See the regex demo. The (?:\/.*)?$ matches an optional sequence of / and any 0 or more chars and then the end of string.
You might consider a "cleaner" pattern like
^(?:\w+:\/\/)?(?:[^\/.]+\.)?hello\.net(?:\/.*)?$
See the regex demo. Details:
^ - start of string
(?:\w+:\/\/)? - an optional occurrence of 1+ word chars, and then :// char sqequence
(?:[^\/.]+\.)? - an optional occurrence of any 1 or more chars other than / and . and then .
hello\.net - hello.net
(?:\/.*)?$ - an optional occurrence of / and then any 0+ chars and then end of string
I search a regex in PHP to match a simple URL path with specific characters and not more.
My regex don't work exactly (flag 'gm' only for test. in working process please without 'g' for more exactly.):
/^\/[A-Za-z0-9-]+\/?[A-Za-z0-9-]+\/?[A-Za-z0-9-]+\/?[A-Za-z0-9-]+\/?$/gm

I have no idea it works with {n}.
Only this charset: A-Z a-z 0-9 - / and exactly no more. Please no \d for digits.
It's for a !preg_match() in PHP.
EDIT: Leading slash is a must have. Double slash and more is not allowed. Trailing slash yes or no.
It appears the URL should only be valid if there are not more than 5 slashes.
You may adjust your pattern as
^(?!(?:[^\/]*\/){5})(?:(?:\/[A-Za-z0-9-]+){1,4}\/?|\/)$
See regex demo
Details
^ - start of string
(?!(?:[^\/]*\/){5}) - a negative lookahead that fails the match if there are 5 occurrences of / chars in the string
(?: - start of the non-capturing group:
(?:\/[A-Za-z0-9-]+){1,4}\/? - 1 to 4 occurrences of a / and 1+ ASCII alphanumeric or - chars and then an optional / char
| - or
\/ - a single / char in the string
) - end of the non-capturing group
$ - end of string.
i need a check on regex, in particular:
/it/categoria/diritti-e-ugualianza
/it/categoria/diritti-e-ugualianza/
/it/categoria/diritti-e-ugualianza?i=1
/it/categoria/diritti-e-ugualianza/?i=1
must be checked in a unique rule
i try with this
/it/categoria/diritti-e-ugualianza(?:/(.*))?$
but it works only with
/it/categoria/diritti-e-ugualianza
/it/categoria/diritti-e-ugualianza/
exists a way to ignore also params?
thank you
You may replace / with a character class [/?] that matches either ? or /:
/it/categoria/diritti-e-ugualianza(?:[?/](.*))?$
^^^^
See the regex demo.
Details
/it/categoria/diritti-e-ugualianza - a literal substring
(?:[?/](.*))? - an optional group matching 1 or 0 occurrences of
[?/] - a ? or /
(.*) - Capturing group 1: any 0+ chars to the end of the line
$ - end of string.
