What would be the correct way of writing a regex that states:
/ followed by any number
For example, gets fired with "/1", "/2", but not "/a" etc.
PCRE
/\/\d/
this will match any '/' followed by any single character number number.
/\/\d+/
this will match '/' followed by any set of consecutive numbers.
/^\/d+$/
this will match '/' followed by any set of consecutive numbers that are the only thing on that line.

I have string that could come in several forms
“PSM000216556880035450088|TRF”
“VNM000216556880035450088|TRF FROM MACK”
“NXG000216556880035450088”
“Transfer from josh SL000216556880035450088 to jack”
“X00000216556880035450088 0098123 TRANSFER 789121”
I need a Regex pattern that could get the string that starts with PSM, VNM, NXG, SL00 or X00.
i.e. in 1, I need “PSM000216556880035450088”. This string is the reference and it is what I need. It can be found in any position in a sentence and sometimes the reference might not be separated from the other words by a space. Sometimes a special character can be used as a separator. i…e. in 2 “VNM000216556880035450088|TRF FROM MACK”.
I will be using the Regex in my VB.NET code.
What about this with multiline flag?
((?:PSM|VNM|NXG|(SL|X)00)\d+)

I'm looking for regex-way to find if a string matches any of this pattern:
2.
1.2
3.4.5
These numbers are taken from the numbering list of Word.
If you only want to match what is above, use ^((\d\.)+\d|(\d\.))$. (Link to regex tester).
This will either match that first kind of pattern (with a digit and then a period) or the other two, which have a digit followed by a period more than 1 time, and another digit at the end.
If you also want to match patterns like 3.4., i.e., strings that may or may not end in a period, you can use ^(\d\.)+\d?$ (Link)
This matches patterns that have a digit followed by a period one or more times, and then maybe a digit after that.

Can someone tell me how to allow in Regex all a-zA-Z0-9 except 6 digits long number?
So true for:
1234567
a123456
123456P
3A237bdb8
but false for
123456
I want to
allow only letters and digits
deny 6 digit long number (like 123456) and other not letter characters like -_+,.!##$ etc.
If your regex engine supports lookahead, you can use:
^(?!\d{6}$)[a-zA-Z0-9]+$

I am looking for a regex matches any string in the following format:
string#substring -> where substring = substring of the string and string is only letters from a to d
e.g.
abcddd#cd accepted
abcddd#cccc not accepted
This regex should meet your requirements:
[a-d]*?([a-d]+)[a-d]*#\1
It matches abcddd#cd but doesn't match abcddd#cccc.
Depending on your choice of tool and how you use it, you may or may not have to anchor it with a ^ and $ at the beginning and end respectively (turning it into ^[a-d]*?([a-d]+)[a-d]*#\1$).
Experiment here.

having a hard time to find regex solution.
The value in database's field "product_id" can be in either format:
{"value":"e19f2b3e-9919-421e-a125-95fdd989459d"}
{"itemUuid":"8fe2a09e-aade-485c-b847-e83a780f1b8e"}
Need to write a regex capturing BOTH cases, so the result will be:
e19f2b3e-9919-421e-a125-95fdd989459d
8fe2a09e-aade-485c-b847-e83a780f1b8e
What I already did (in Vertica syntax) is
trim(TRAILING '"}' from regexp_substr(me.value, '[0-9].*'))
which doesn't capture the id if it starts with alphabetic character.
You can use the RegEx (?<=:").+(?="})
(?<=:") makes sure there is :" before your match
.+ matches any char at least once
(?="}) makes sure there is"} after your match
Demo.
