Can you please help me with reg ex. I cant make it :( I hate regex.
I need to match this string ${ANY_TEXT} .Exactly one "${" and exactly one closing tag "}".
Thanks a lot. :)
\$\{[^}]+\} will match it. It will match ${ABC} from ${ABC}}} as well. If you want to match complete lines, simply anchor the regular expression using ^\$\{[^}]+\}$.
A good site to learn regular expressions is http://www.regular-expressions.info/.
I suppose this covers all the texts.
/^\$\{[a-zA-Z]\}$/

Please help me with my requirement to match only specific pattern.
We have a string for example Jeorge Sally (34). my application should always pick the value that matches the pattern any name with (34).
I tried the following regex [A-z (34)]* but this is giving the different values also such as Adam siva (.
Thanks.
I believe the regex you are looking for is something like this:
^[A-z]+\s[A-z]+\s\(34\)$
This will match any first name, a space, a last name and then the 34 in brackets. Notice the brackets are escaped using a backslash.
I recommend using an online tool such as RegExr or Regex101 when you are trying to figure out where you are going wrong with your regular expressions as they provide visual aid to guide you.
I am not an expert of Regexp literally but I got a regex which is for file matching in the source of one site, but it's not matching any file.
The expression is:
"^(([a-zA-Z]:)|(\\\\{2}\\w+)\\$?)(\\\\(\\w[\\w].*))+(.jpg|.JPG|.jpeg|.JPEG)$";
Is there any expression which matches or qualifies the test of above regexp.
Please Help.
Thank You
First thing is that it is in javascript so to test it on a tester, you need to replace \\ by a single \.
I'm not sure what you are trying to achieve but here are some examples of paths that will match your regex : https://regex101.com/r/Gso9Yx/2
Hope this helps...
Try simplifying it a bit.
[\w,\s-]+(\.jpe?g|\.JPE?G)$
I am a complete regular expression idiot, just keep that in mind :)
I am trying to create a regular expression that will match link:xxxxxx where everything after link: is a wildcard.
Can i just do link:* or am I totally misguided?
link:.* should work correctly.
. matches any character, and you want to repeat it "0 to unlimited" times so you add *.
If you're new to regex, a good way to learn it is by using regex101.
For your problem, you can check out this regex101 example
(Note that I have also added the g modifier, which means that you want to select all matches, not just the first matching line)
I need to find a regular expression which will support the following format
.[A-Z-a-z]/-
Would ^(\.[A-Za-z]\/-?)+$ work fine ?
i.e
.V/-.E/-
BUT THE - IS OPTIONAL
I trield ^(\.[A-Za-z]\/-)$
but i cannot seem to find a regular expression to support the - at the end
Could someone show me where i am going wrong please.
Thanks
If you want the regex to match the string ".V/-.E/-", you could use this:
^(\.[A-Za-z]\/\-?)+$
This should be as simple as adding a ? after the -. The whole regex would be ^\.[A-Za-z]\/-?$ (don't need the parens unless you are using backreferences)
i have following regular expression but it's not working properly it takes only three values after # sign but i want it to be any number length
"/^[a-zA-Z0-9_\.\-]+\#([a-zA-Z0-9\-]+\.)+[a-zA-Z0-9]{2,4}$/"
this#thi This is validated
this#this It is not validating this expression
Can you please tell me what's the problem with the expression...
Thanks
If you want your regex to match "any number length" then why are you using {2,4}?
I think a better example of the strings you're trying to match might give others a better idea of what you want, because based on your regex it is a bit confusing what you're looking for.
Try this:
^[a-zA-Z0-9_.-]+#([a-zA-Z0-9-]+\.)+[a-zA-Z0-9]{2,4}$
The main problem is that you didn't escape the dot: \.. In regular expression the dot matches everything (mostly), making your regex quite liberal.
