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.

Simple regex question. I have a string on the following format:
XYICD27A3 (MN PqrstUvw MFP E34540)
What will be the regular expression to match this string. I have tried:
(^([a-zA-Z0-9-_#&:.#$ s]+)$)
this, but it's not matching the whole string
According to your comment, I corrected your regex like this:
[a-zA-Z0-9\s]+\([a-zA-Z0-9_#&:.# -]+\)

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+)

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

Today I attemped several time to build regular expression to validate a set of double number with semi-colon delimeted following example data below:
Should match:
123.1234567890
123.1234567890;123.1234567890;123.1234567890
Should not match:
123.1234567890;
123.1234567890;123.1234567890;123.1234567890;
If you have any idea, Could you please help me ?
Thank you very much
You can try this:
(\d+\.\d+;)*\d+\.\d+(?![\d;])
to match the whole 123.1234567890;123.1234567890;123.1234567890
\d+\.\d+(?![\d;])
to match just the last.

I'm looking for the regular expression to find failures in a log file.
The format is "Failures: " following the number of error, a digit not zero
Thanks!
You can use this:
"Failures:\s+[1-9]\d*"
this would be what you are looking for:
Failures:\s*[1-9]\d*
btw, you may want to know that in character class, the not notation is ^, not !.
E.g. [^a-zA-Z] means not letters.
