I have received a very long file. It has 1000+ lines of SQL code. Each line start with line number.
14 PROCEDURE sp_processRuleset(pop_id IN NUMBER);
15
16 -- clear procedure for preview mode to clean crom_population_member_temp table and global variables
17 PROCEDURE sp_commit; -- 28-Oct-09 J.Luo
18
19 -- The rule Set string for the Derived Population Member Preview
20 -- The preview mode will set gv_context_ruleSet by setContext_ruleSet,
21 -- sp_processRuleset uses gv_context_ruleSet to build derived population instead of getting rules from crom_rule_set table
22 gv_context_ruleSet VARCHAR2(32767) := NULL; -- 27-Oct-09 J.Luo
23 -- The population Role Id for the Derived Population Member Preview
I want to remove only line numbers using NotePad++ Find+Replace functionality. Is there any regex available to get this done ?
This using regex is the easiest way.
Other handy way (scrolling a 1K lines is not much IMO) could be :
Block Selection using ALT key and dragging your mouse, like following:
You can use this regex:
^\d+
Working demo
Open Replace window with CTRL+H and run Replace All with these settings:
Find what: ^\s*\d+
Replace with: (empty)
Search mode: Regular expression
Notes:
\s can also be [[:space:]] or [ \t]
\d can also be [[:digit:]] or [0-9]
If the new edit is correct, the pattern \s* that matches the leading space may not be needed.
You can use this one if you have colon after numbers
^\d+:

I have a filename like this:
0296005_PH3843C5_SEQ_6210_QTY_BILLING_D_DEV_0000000000000183.PS.
I needed to break down the name into groups which are separated by a underscore. Which I did like this:
(.*?)_(.*?)_(.*?)_(.*?)_(.*?)_(.*?)_(.*?)_(.*?)_(.*?)(\d{16})(.*)
So far so go.
Now I need to extract characters from one of the group for example in group 2 I need the first 3 and 8 decimal ( keep mind they could be characters too ).
So I had try something like this :
(.*?)_([38]{2})(.*?) _(.*?)_(.*?)_(.*?)_(.*?)_(.*?)_(.*?)_(.*?)(\d{16})(.*)
It didn’t work but if I do this:
(.*?)_([PH]{2})(.*?) _(.*?)_(.*?)_(.*?)_(.*?)_(.*?)_(.*?)_(.*?)(\d{16})(.*)
It will pull the PH into a group but not the 38 ? So I’m lost at this point.
Any help would be great
Try the below Regex to match any first 3 char/decimal and one decimal
(.?)_([A-Z0-9]{3}[0-9]{1})(.?)(.*?)(.?)_(.?)(.*?)(.?)_(.?)
Try the below Regex to match any first 3 char/decimal and one decimal/char
(.?)_([A-Z0-9]{3}[A-Z0-9]{1})(.?)(.*?)(.?)_(.?)(.*?)(.?)_(.?)
It will match any 3 letters/digits followed by 1 letter/digit.
If your first two letter is a constant like "PH" then try the below
(.?)_([PH]+[0-9A-Z]{2})(.?)(.*?)(.?)_(.?)(.*?)(.?)_(.?)
I am assuming that you are trying to match group2 starting with numbers. If that is the case then you have change the source string such as
0296005_383843C5_SEQ_6210_QTY_BILLING_D_DEV_0000000000000183.PS.
It works, check it out at https://regex101.com/r/zem3vt/1
Using [^_]* performs much better in your case than .*? since it doesn't backtrack. So changing your original regex from:
(.*?)_(.*?)_(.*?)_(.*?)_(.*?)_(.*?)_(.*?)_(.*?)_(.*?)(\d{16})(.*)
to:
([^_]*)_([^_]*)_([^_]*)_([^_]*)_([^_]*)_([^_]*)_([^_]*)_([^_]*)_(.*?)(\d{16})(.*)
reduces the number of steps from 114 to 42 for your given string.
The best method might be to actually split your string on _ and then test the second element to see if it contains 38. Since you haven't specified a language, I can't help to show how in your language, but most languages employ a contains or indexOf method that can be used to determine whether or not a substring exists in a string.
Using regex alone, however, this can be accomplished using the following regular expression.
See regex in use here
Ensuring 38 exists in the second part:
([^_]*)_([^_]*38[^_]*)_([^_]*)_([^_]*)_([^_]*)_([^_]*)_([^_]*)_([^_]*)_(.*?)(\d{16})(.*)
Capturing the 38 in the second part:
([^_]*)_([^_]*)(38)([^_]*)_([^_]*)_([^_]*)_([^_]*)_([^_]*)_([^_]*)_([^_]*)_(.*?)(\d{16})(.*)
I am trying to use Regex to parse a series of strings to extract one or more text dates that may be in multiple formats. The strings will look something like the following:
24 Aug 2016: nno-emvirt010a/b; 16 Aug 2016 nnt-emvirt010a/b nnd-emvirt010a/b COSI-1.6.5
24.16 nno-emvirt010a/b nnt-emvirt010a/b nnd-emvirt010a/b EI.01.02.03\
9/23/16: COSI-1.6.5 Logs updated at /vobs/COTS/1.6.5/files/Status_2016-07-27.log, Status_2016-07-28.log, Status_2016-08-05.log, Status_2016-08-08.log
I am not concerned about validating the individual date fields; just extracting the date string. The part I am unable to figure out is how to not match on number sequences that match the pattern but aren’t dates (‘1.6.5’ in ex. (1) and 01.02.03 in ex. (2)) and dates that are part of a file name (2016-07-27 in ex. (3)). In each of these exception cases in my input data, the initial numbers are preceded by either a period(.), underscore (_) or dash (-), but I cannot determine how to use this to edit the pattern syntax to not match these strings.
The pattern I have that partially works is below. It will only ignore the non date matches if it starts with 1 digit as in example 1.
/[^_\.\(\/]\d{1,4}[/\-\.\s*]([1-9]|0[1-9]|[12][0-9]|3[01]|[a-z]{3})[/\-\.\s*]\d{1,4}/ig`
I am not sure about vba check if this works . seems they have given so much options : https://www.safaribooksonline.com/library/view/regular-expressions-cookbook/9781449327453/ch04s04.html
^(?:(1[0-2]|0?[1-9])/(3[01]|[12][0-9]|0?[1-9])|↵
(3[01]|[12][0-9]|0?[1-9])/(1[0-2]|0?[1-9]))/(?:[0-9]{2})?[0-9]{2}$
^(?:
# m/d or mm/dd
(1[0-2]|0?[1-9])/(3[01]|[12][0-9]|0?[1-9])
|
# d/m or dd/mm
(3[01]|[12][0-9]|0?[1-9])/(1[0-2]|0?[1-9])
)
# /yy or /yyyy
/(?:[0-9]{2})?[0-9]{2}$
According to the test strings you've presented, you can use the following regex
See this regex in use here
(?<=[^a-zA-Z\d.]|^)((?:\d{1,2}\s*[A-Z][a-z]{2}\s*\d+)|(?:(?:\d{1,2}\/){2}\d+)|(?:\d+(?:-\d{2}){2})|\d{2}\.\d{2})(?=[^a-zA-Z\d.])
This regex ensures that specific date formats are met and are preceded by nothing (beginning of the string) or by a non-word character (specifically a-z, A-Z, 0-9) or dot .. The date formats that will be matched are:
24 Aug 2016
24.16
9/23/16
The regex could be further manipulated to ensure numbers are in the proper range according to days/month, etc., however, I don't feel that is really necessary.
Edits
Edit 1
Since VBA doesn't support lookbehinds, you can use the following. The date is in capture group 1.
(?:[^a-zA-Z\d.]|^)((?:\d{1,2}\s*[A-Z][a-z]{2}\s*\d+)|(?:(?:\d{1,2}\/){2}\d+)|(?:\d+(?:-\d{2}){2})|\d{2}\.\d{2})(?=[^a-zA-Z\d.])
Edit 2
As per bulbus's comment below
(?:[^\w.]|^)((?:\d{1,2}\s*[A-Z][a-z]{2}\s*\d{2,4})|(?:(?:\d{1,2}\/){2}\d{2,4})|(?:\d{2,4}(?:-\d{2}){2})|\d{2}\.\d{2})
Took liberty to edit that a bit.
replaced [^a-zA-Z\d.] with [^\w.], comes with added advantage of excluding dates with _2016-07-28.log
Due to 1 removed trailing condition (?=[^a-zA-Z\d.]).
Forced year digits from \d+ to \d{2,4}
Edit 3
Due to added conditions of the regex, I've made the following edits (to improve upon both previous edits). As per the OP:
The edited pattern above works in all but 2 cases:
it does not find dates with the year first (ex. 2016/07/11)
if the date is contained within parenthesis in the string, it returns the left parenthesis as part of the date (ex. match = (8/20/2016)
Can you provide the edit to fix these?
In the below regexes, I've changed years to \d+ in order for it to work on any year greater than or equal to 0.
See the code in use here
(?:[^\w.]|^)((?:\d{1,2}\s+[A-Z][a-z]{2}\s+\d+)|(?:(?:\d{1,2}\/){2}\d+)|(?:\d+(?:\/\d{1,2}){2})|(?:\d+(?:-\d{2}){2})|\d{2}\.\d+)
This regex adds the possibility of dates in the XXXX/XX/XX format where the date may appear first.
The reason you are getting ( as a match before the regex is the nature of the Full Match. You need to, instead, grab the value of the first capture group and not the whole regex result. See this answer on how to grab submatches from a regex pattern in VBA.
Also, note that any additional date formats you need to catch need to be explicitly set in the regex. Currently, the regex supports the following date formats:
\d{1,2}\s+[A-Z][a-z]{2}\s+\d+
12 Apr 17
12 Apr 2017
(?:\d{1,2}\/){2}\d+
1/4/17
01/04/17
1/4/2017
01/04/2017
\d+(?:\/\d{1,2}){2}
17/04/01
2017/4/1
2017/04/01
17/4/1
\d+(?:-\d{2}){2}
17-04-01
2017-04-01
\d{2}\.\d+ - Although I'm not sure what this date format is even used for and how it could be considered efficient if it's missing month
24.16
I want to get all text that does not start with 1,2,12,34.
I wrote
^((?!1|2|12|34).)*$
(^ asserts position at start of a line)
as in:
https://regex101.com/r/gI6sN8/14
Problems
It also doesn't select text that has 1 or 2 in the middle ("AB 1 CD").
It also doesn't select 13 (because it starts with 1)
How can I restrict it
Looks like you want this:
^(?!(1|2|12|34)\s).*
https://regex101.com/r/gI6sN8/16
As mentioned in comment, you need word boundary and correct parenthesis position
^(?!(?:1|2|12|34)\b)(.*)$
Regex Demo
You can also use \D
^(?!(?:1|2|12|34)\D)(.*)$
In your regex
^((?!1|2|12|34).)*$
you are finding whether any of the above alternative 1|2|12|34 is correct at every position. That's why it's not matching AB 1 CD
This works
^(?!(?:12?|2|34)(?!\d)).+$
https://regex101.com/r/gI6sN8/19
A valid boundary between the numbers you don't want it to
start with and the character after it appears to be any non-digit.
I'm trying to select every occurrence of 4 leading spaces on each line of a file to replace them with 2 spaces in order to reformat. The Find All regex I ended up using was:
^ {4}|(?<=^ {4}) {4}|(?<=^ {8}) {4}|(?<=^ {12}) {4}|(?<=^ {16}) {4}
I've made a demo here showing exactly how I expect it to highlight the file.
Is there a better way of achieving this? Note I want Sublime Text to individually select each group of 4 spaces, I don't want each line containing leading white-space to be all in one selection.
^(?:( ) )(?:( ) )?(?:( ) )?(?:( ) )? replace with \1\2\3\4
Is functionally equivalent and doesn't require lookbehind.
It requires about 9% of the effort for the regex engine as well (702 vs 7680 steps).
How can I write this as a regular expression?
tabspaceSTRINGtabspace
My data looks like this:

I want to get

34562 30
12313 30
1232131 30
\t*\t doesn't work.
try the following regular expression
\t.+\t
The problem there is your definition of String...
If you use something like the suggested above, it'll match
tabspaceSTRINGtabspacetabspace
You get the picture. This might be acceptable, if not, you need to limit your "STRING" definition, like:
\t\w+\t
or:
\t[a-zA-Z]+\t
What characters are allowed in your string?
\t\w+\t
\w would allow letters, digits and the underscore (depending on your regex engine ASCII or Unicode)
See it here on Regexr, a good platform to test regular expressions.
Your "regex" \t*\t would match 0 or more tabs and then one tab. The * is a quantifier meaning 0 or more and is referring to the character or group before (here to your \t)
If your whitespace are not tabs, try this
\s+.+\s+30
\s is a whitespace character (space, tab, newline (not important for Notepad++)).
If you are not sure about the strings you are looking for except that they are separated by tabs it is a good approach to describe such a string as everything but a tab: (^\t*)
[^\t]*\t([^\t]*)\t[^\t]*
