I have a list that could look sort of like
("!Goal 27' Edward Nketiah"),
("!Goal 33' 46' Pierre Emerick-Aubameyang"),
("!Sub Nicolas Pepe"),
("Jordan Pickford"),
and I'm looking to match either !Sub or !Goal 33' 46' or !Goal 27'
Right now I'm using the regex (!\w+\s) which will match !Goal and !Sub, but I want to be able to get the timestamps too. Is there an easy way to do that? There is no limit on the number of timestamps there could be.
As I mentioned in my comment, you can use the following regex to accomplish this:
(!\w+(?:\s\d+')*)
Explanation:
(!\w+(?:\s\d+')*) capture the following
! matches this character literally
\w+ matches one or more word characters
(?:\s\d+')* match the following non-capture group zero or more times
\s match a whitespace character
\d+ matches one or more digits
' match this character literally
Additionally, the first capture group isn't necessary - you can remove it to simply match:
!\w+(?:\s\d+')*
If you need each timestamp, you can use !\w+(\s\d+')* and split capture group 1 on the space character.
If your input always follows the format "bang text blank digits apostrophe blank digits apostrophe etc", then it should be as simple as:
!\w+(?:\s\d+')*
Explanation:
! matches an exclamation mark
\w+ matches 1 or more word-characters (letters, underscores)
(?:…) is a non-capturing group
\s matches a single whitespace character
\d+ matches one or more digits
' matches the apostrophe character
* repeatedly matches the group 0 or more times
this :
(!\w+(?:\s\d+')*)
will capture :
"!Goal 27'"
"!Goal 33' 46'"
"!Sub"

For example I want to match three values, required text, optional times and id, and the format of id is [id=100000], how can I match data correctly when text contains spaces.
my reg: (?<text>[\s\S]+) (?<times>\d+)? (\[id=(?<id>\d+)])?
example source text: hello world 1 [id=10000]
In this example, all of source text are matched in text
The problem with your pattern is that matches any whitespace and non whitespace one and unlimited times, which captures everything without getting the other desired capture groups. Also, with a little help with the positive lookahead and alternate (|) , we can make the last 2 capture groups desired optional.
The final pattern (?<text>[a-zA-Z ]+)(?=$|(?<times>\d+)? \[id=(?<id>\d+)])
Group text will match any letter and spaces.
The lookahead avoid consuming characters and we should match either the string ended, or have a number and [id=number]
Said that, regex101 with further explanation and some examples
You could use:
:\s*(?<text>[^][:]+?)\s*(?<times>\d+)? \[id=(?<id>\d+)]
Explanation
: Match literally
\s* Match optional whitespace chars
(?<text> Group text
[^][:]+? match 1+ occurrences of any char except [ ] :
) Close group text
\s* Match optional whitespace chars
(?<times>\d+)? Group times, match 1+ digits
\[id= Match [id=
(?<id>\d+) Group id, match 1+ digirs
] Match literally

}
I want to capture exactly arn:aws:ec2:us-east-1:123:security-group/sg-123abc in this example. Generically, I want to capture the value of Id regardless of placement. My current solution is /Details={.*Id=(.*\w)/, but this only works if it's the last object in the data. How can I take into account the following potential scenario:
Id=arn:aws:ec2:us-east-1:123:security-group/sg-123abc, Thing=123abc}]
You have a pattern with 2 times .* which will first match till the end of the line/string (depending on if the dot matches a newline) and it will backtrack to match the last occurrence where this part of the pattern Id=(.*\w) can match.
If you want to use a capture group, you can make the format and the allowed characters a bit more specific:
\bId=(\w+(?:[:\/-]\w+)+)
The pattern in parts
\b A word boundary to prevent a partial word match
Id= Match literally
( Capture group 1
\w+ Match 1+ word chars
(?:[:\/-]\w+)+ Repeat 1+ times either : / - and 1+ word chars
) Close group 1
Regex demo
Or if you know that it starts with Id=arn:
\bId=(arn:[\w:\/-]+)
Regex demo
Note that you don't have to escape the \/ only when the delimiters of the regex are forward slashes, but there is no language tagged.
You can use look-behind to check that there is the Id= prefix, and then match anything that is not a space, comma or closing brace:
(?<=\bId=)[^,}\s]*
I want to pull the second string in a commma delimited list where the first value is numeric and the second is alpha.
I'm using \d[^,]+(?=,) to pull the numeric value in the first field and just need help with pulling the second value from the "Name" column.
Here's part of a sample file that I'm trying to extract data from:
Address Number,Name,Employee Master Exist(Y/N),Auto-Deposit Exists(Y/N),Supplier Master Exists(Y/N),Supplier Master Created,ACH Account Exists(Y/N),ACH Account Created,ACH Same as Auto-deposit(Y/N)
//line break here is for clarity and does not exist in file//
4398,Presley Elvis Aaron,Y,N,Y,N,Y,N,N
10154,Shepard Alan Barrett,Y,Y,Y,N,Y,N,N
You could make use of a capturing group if you want to match the second string by first matching 1+ digits and a comma.
Then capture in a group matching 1+ chars a-zA-Z and match the trailing comma.
^\d+,([a-zA-Z]+(?: [a-zA-Z]+)*),
^ Start of string
\d+, Match 1+ digits and a comma (Or use (\d+), if the digits should also be a group)
( Capture group 1
[a-zA-Z]+ Match 1+ chars a-zA-Z
(?: [a-zA-Z]+)* Repeat matching the same as previous preceded by a space
), Close capturing group and match trailing comma
Regex demo
To get a bit broader match you could use this pattern to match at least a single char a-zA-Z
\d+,([a-zA-Z ]*[a-zA-Z][a-zA-Z ]*),
Regex demo
Note that this part in your pattern \d[^,]+ matches not only digits, but 1 digit followed by 1+ times any char except a comma which would for example also match 4a$ .
You could try this regex:
^\d+,([^,]+),
This will look for lines:
starting with one or more digits
followed by a comma
capture anything that is not a comma
followed by a comma
See it at Regex 101
If not all lines contain a name, then change the + to a *:
^\d+,([^,]*),
See alternative regex
The words' length could be 2 or 6-10 and could be separated by space or comma. The word only include alphabet, not case sensitive.
Here is the groups of words that should be matched:
RE,re,rereRE
Not matching groups:
RE,rere,rel
RE,RERE
Here is the pattern that I have tried
((([a-zA-Z]{2})|([a-zA-Z]{6,10}))(,|\s+)?)
But unfortunately this pattern can match string like this: RE,RERE
Look like the word boundary has not been set.
You could match chars a-z either 2 or 6 - 10 times using an alternation
Then repeat that pattern 0+ times preceded by a comma or a space [ ,].
^(?:[A-Za-z]{6,10}|[A-Za-z]{2})(?:[, ](?:[A-Za-z]{6,10}|[A-Za-z]{2}))*$
Explanation
^ Start of string
(?:[A-Za-z]{6,10}|[A-Za-z]{2}) Match chars a-z 6 -10 or 2 times
(?: Non capturing group
[, ](?:[A-Za-z]{6,10}|[A-Za-z]{2}) Match comma or space and repeat previous pattern
)* Close non capturing group and repeat 0+ times
$ End of string
Regex demo
If lookarounds are supported, you might also assert what is directly on the left and on the right is not a non whitespace character \S.
(?<!\S)(?:[A-Za-z]{6,10}|[A-Za-z]{2})(?:[ ,](?:[A-Za-z]{6,10}|[A-Za-z]{2}))*(?!\S)
Regex demo
([a-zA-Z]{2}(,|\s)|[a-zA-Z]{6,10}|(,|\s))
This one will get only the words who have 2 letter, or between 6 and 10
\b,?([a-zA-Z]{6,10}|[a-zA-Z]{2}),?\b
You can use this
^(?!.*\b[a-z]{4}\b)(?:(?:[a-z]{2}|[a-z]{6,10})(?:,|[ ]+)?)+$
Regex Demo
This regex will match your first case, but neither of your two other cases:
^((([a-zA-Z]{2})|([a-zA-Z]{6,10}))(,|[ ]+|$))+$
I'm making the assumption here that each line should be a single match.
Here it is in action.
I have a string like a Taxi:[(h19){h12}], HeavyTruck :[(h19){h12}] wherein I want to keep information before the ":" that is a taxi or heavy truck . can somebody help me with this?
This will capture a single word if it's followed by :[ allowing spaces before and after :.
[A-Za-z]+(?=\s*:\s*\[)
You'll need to set regex global flag to capture all occurrences.
I think this will do the trick in your case: (?=\s)*\w+(?=\s*:)
Explanation:
(?=\s)* - Searches for 0 or more spaces at the begging of the word without including them in the selection .
\w+ - Selects one or more word characters.
(?=\s*:) - Searches for 0 or more white spaces after the word followed by a column without including them in the selection.
To match the information in your provided data before the : you could try [A-Za-z]+(?= ?:) which matches upper or lowercase characters one or more times and uses a positive lookahead to assert that what follows is an optional whitespace and a :.
If the pattern after the colon should match, your could try: [A-Za-z]+(?= ?:\[\(h\d+\){h\d+}])
Explanation
Match one or more upper or lowercase characters [A-Za-z]+
A positive lookahead (?: which asserts that what follows
An optional white space ?
Is a colon with the pattern after the colon using \d+ to match one or more digits (if you want to match a valid time you could update this with a pattern that matches your time format) :\[\(h\d+\){h\d+}]
Close the positive lookahead )
