How can I allow a dot in an URL using Regex? Any advice?
thanks

\. will allow you to match a dot. How you insert that into your regex depends on how you've created your regex.

. in a regex allows any character (except newlines, depending on the engine and its options), so you have to escape it as \.

Since you're being vague, so will I:
\.
There's the regex to allow a dot.

use the \ to escape native match chrs

here is my regex
mywebsite/|mywebsite/myweb.html
Done it :-) thanks everyone
^mywebsite\/myweb\.html|mywebsite\/$
Is this what you want as a result?
mywebsite(/m.*|/)
You could try the following, I could be more precise if you show us the regex you are actually using.
(WhateverYouAreUsing){2}
(...) is a group and {...} is a quantifier, it will take exactly two of the matches you are looking for. {1,2} will take at least one and at maximum two, in case there is only one and you still want to get a match.
Put some parentheses in your regex and escape the .:
(mywebsite/)|(mywebsite/myweb\.html)
Alternatively, for something a little more general:
(\w+/)|(\w+/\w+\.html)

I need to send SMS to my subscribers through the API, the API doesn't support fancy apostrophe, so i would like to remove that from the message before send it to the user. So i'm looking for a regular expression that should remove the fancy apostrophe and any other unsupported characters, at the same time message can have special characters.
You can use \u to allow any unicode character. If you have a limited set of unsupported characters that can be listed, then you can use character class negation by enclosing the unsupported characters in [^ and ].

I need a regular expression for CLIA number. CLIA number is combination alpbh numeric without any spaces. Now i am using this expression /^[A-Za-z0-9]{10}$/ am i using correct expression?
you can use this....
/^[a-Z]{4}[0-9]{6}$/
^ this is used to beginning of the line.
$ end of the line.
a-Z this will match the both cases.
this case will match the four alpha character and six numbers. so totally 10 alphanumbers.
Based on your example, it sounds like you want the first four characters to be "CLia" followed by 6 digits? If so, use /^CLia\d{6}$/. If not, be more specific.
If your language support POSIX classes :
/^[[:alnum:]]{10}$/

I need a regular expression which can detect 5 consecutive occurrences of any digit or character as given in below examples :
A11111C2 – INVALID
AAAAAAA21 – INVALID
12AXXXXX – INVALID
GGGG112 – VALID
You can match five consecutive characters with (.)\1\1\1\1. So .*(.)\1\1\1\1.* matches all your invalid cases.
The \1 is a backreference, so it only matches exactly what the first group (.) matched.
