Use $ anchor to mark the end of the string:
.{3,5}$
3 above is the min number of characters to match; 5 is max.

Hi this is my example 0xc1e5017fbc68aa3e56aa580708de9aa123d62d18
This is my reg ex ^0x[a-fA-F0-9]{1,40}. What I'm doing is 0x which is compulsory after that we can enter upto 40 alpha numeric digits. But not special characters. What should I do here so it will match correctly?
Your issue is that you need to assert where the string ends, or else you will match up until a special character is found, and get undesired matches.
So with your current regex and test string 0xc1!, 0xc1 would be matched, even though it is an invalid match.
How about using: ^0x[a-fA-F0-9]{1,40}$

PHP: RegEx for string with 3-9 letters and 5-50 numbers
(2 answers)
Closed 5 years ago.
I want to match a string that has the following requirements:
The string contains 5 to 10 digits. [0-9]
Contains 2 to 3 letters. [a-z]
for example
123a2bc12
s123d456
This is my regular expression. /^\d*[a-z]\d*[a-z]\d*[a-z]?\d*$/. But this can only limit the number of letters.
It isn't pretty but this should be what you're looking for:
^(?=(?:[^a-zA-Z]*[a-zA-Z]){2,3}[0-9]*$)(?=(?:[^0-9]*[0-9]){5,10}[A-Za-z]*$).*$
I think you want to this
s=re.search(r'(\w+)','123a2bc12').group(1)
print s #The output is '123a2bc12'

I need to have a regular expression to restrict the number of digits in a string which may contain alphabets or any other characters along with digits. Is this possible with regular expressions ?
The idea is to anchor beginning and end of string and allow exactly n repetitions of a digit with something else. For example, exactly 6 digits in a string:
^\D*(\d\D*){6}$
