I believe my validation is correct however it is not working.
My regular expression pattern is
ValidationExpression= "(I|II|III|IV)[DEF]?"
Basically, the user should put any of the first options then with optional D, E or F
Valid text Example: IIIC
Thank you
I don't know much about regex, but I did a quick bit of googling and came up with this:

It explains how it works at the side :)

I am trying to find an expression that can be used extract a string after a specific number of characters.
E.g
FR_EN_BR_Student_Exact
FR_EN_NB_Student_Exact
I would want a pattern that can take all characters past the second underscore ( not including the underscore.
Would appreciate any ideas!

I want to select the second 'M' in the following string using regex.
So, the M after T.
P3Y6M4DT12H30M5S
Sometimes the string looks like one of these:
PT12H30M5S
PT12H30M5.234523S
I've tried multiple expressions and searched for a similar case but couldn't find anything.
Could someone help me build an expression to select the M after T so I can use it in my regex replace function?
(?!.+T.+)(M)
Selects everything until the first T and then selects everything until the first M and captures it.

I'd like to setup auto download of some Anime using an RSS feed, but only 720p versions. The format never changes and it always looks like below.
[Blahblah] Blahepisode - 12 [720p].mkv
Here is the regex I have come up with but cannot get to work properly.
/.\+[720p]+/g
Any help would be appreciated!
Assuming you have lines that look like your example, it will be mached with the following Regex:
.+(?:\[720p\].mkv)
It maches one or more chacacters at start, followed by '[720p].mkv'.
Note that the Square brackets are escaped to '\[' and '\]', otherwise they have special meaning.
if you only need '[720p]' then you can use:
\[720p\]

I have developed some regex in regexr where it works as expected, but when I use it in Go it seems to be mismatching strings.
(\+|-)?(((\d{1,3}[, ])(\d{3}[ ,])*\d{3})|\d+)( ?[\.,] ?(\d{3}[, ])*\d+)?
For example in regexr the following input does not match:
1.12,4.64
But in Go it does match.
^(\+|-)?(((\d{1,3}[, ])(\d{3}[ ,])*\d{3})|\d+)( ?[\.,] ?(\d{3}[, ])*\d+)?$
Try with anchors.^$ will disable partial matching.See demo.
