This is my regex for address validation right now
^[a-z-A-Z\ \d\#\-\.\`\\\/\'\(\)]+$
Now I need to make sure the address has mandatory house number
I changed to:
^[\d*a-z-A-Z\ \d\#\-\.\`\\\/\'\(\)]+$
but it's not working.
I need to check against this address:
8952 West Auburn St
If you want a number, followed by any of these [a-z-A-Z\ \d#-.\/'()], this is what you are looking for
^\d{1}[a-z-A-Z\ \d#-.\/'()]+$
It mean, it starts with a digit, with a length of at least 1, then matches anything in the square brackets, as many characters if you want

I am new in programming. I want to implement phone number validation using javascript in my website. I want some regex with conditions below:
a digit with length of 11
it should start with 09
no any string or space in the input is accepted
e.g.
"09131234455" // is accepted
"091 05488963" // not accepted
thanks anyone can help!!
Try: ^09\d{9}$ (first '09', then 9 digits, all this surrounded with
"start of string" and "end of string" anchors).

I have a sentence example: I am just one man I', trying to capture am just on with the following regex, but it also captures I which is not what I need.
(?=I).*(?= man)
The result is: I am just one
I don't want extra capturing groups, only the full match which should be am just one.
change the first positive lookahead to a negative (?!I). This won't capture I
(?!I).*(?= one)
By saying look and match anything except I
(?=[^I ]).*(?= man)

I tried this : [fl]ady?[ing] ?[rb]ug!?
I know [fl]ad[y]?(ing)? ?[br]ug!? is an answer
Can this be solved using character sets only? Must match both.

I believe this should work for you
[fl]ad(y|ing)\s?[br]ug?
Check out http://www.regexpal.com/
Using character sets only? So, it doesn't matter what other letter combinations it matches as well? Mmm. Then
[fl]ad[giny]+[\sbrug!]+
would do. See: https://regex101.com/r/FJWJyM/1

I have a text input on my html page. When a user tries to add a new watch I want it to start with WATCH_XXXX (X's are whatever the user inputs). It has to start with WATCH_ all caps with the underscore. I've tried a lot of different ways but I keep getting the "please match the requested format" pop-up. This was the last one I tried -> required pattern="^WATCH_[a-z]". Am I even close to getting this right?
This regex ^WATCH_[a-zA-Z]+$ should work
<form>
<input required pattern="^WATCH_[a-zA-Z]+$"/>
<input type="submit"/>
</form>
Do all characters after "WATCH_" have to be letters? If not ^WATCH_.* may work better.

I'm trying to write regexp to find a string who start and ends with the same number like so :
2aldkc2 <----
4alou4 <----
edit , i forget to motion what i have tried so far :
^(\d).^([^h].*$)
but this doesn't work
Use capturing group.
^(\d).*\1$
The regex captures the first digit and match that particular line only if the last character is also the same as the one captured.
