I am scanning a QR code and need a script to replace the commas with a ( \t)
My results are:
820-20171-002, ,Nov 24, 2020,,,13,283.40,,Mike Shmow
My problem is - I don't want a comma after the date. Right now I have the following - which does work to replace commas with a tab.
decodeResults[0].content.replace(/,/g, "\t");
I am trying to replace the /,/g with an expression to replace all commas except for the 3rd occurrence.
Use
.replace(/(?<!\b[a-zA-Z]{3}\s+\d{1,2}(?=,\s*\d{4})),/g, '\t')

I am new to Regex and I am unable to extract hyponym-hypernym pairs in the form of a list or tuple.
I tried using this pattern but I get no matches
(NP_[\w.]*(, NP_[\w.]*)*,? (and)? other NP_[\w.]*)
I have the following annotated sentences for 'and other' pattern:
NP_kimmel faces NP_dui , NP_fleeing or NP_evading_police , and other NP_possible_charges .
The NP_network has asked NP_big_bang_theory_co-creator_bill prady to mastermind the NP_revival , which would see the NP_return of NP_kermit the NP_frog , NP_miss_piggy , NP_fozzie_bear and other NP_old_favorites .
I want to extract a list such as :
[NP_dui,NP_fleeing or NP_evading_police, NP_possible_charges]
OR
(NP_dui,NP_possible_charges)
(NP_fleeing or NP_evading_police,NP_possible_charges)
Similarly for the sentence 2:
[NP_kermit the NP_frog , NP_miss_piggy , NP_fozzie_bear, NP_old_favorites]
or Similar tuples.
Any help would be appreciated.
Use
NP_[\w.]*(?:\s*(?:,|\bor\b|,?\s*and(?:\s+other)?\b)\s*NP_[\w.]*)+
This extracts strings with your matches. Next, extract expected ents with NP_[\w.]*.
Python code:
import re
test_strs = ["NP_kimmel faces NP_dui , NP_fleeing or NP_evading_police , and other NP_possible_charges.",
"The NP_network has asked NP_big_bang_theory_co-creator_bill prady to mastermind the NP_revival , which would see the NP_return of NP_kermit the NP_frog , NP_miss_piggy , NP_fozzie_bear and other NP_old_favorites ."]
p = r'NP_[\w.]*(?:\s*(?:,|\bor\b|,?\s*and(?:\s+other)?\b)\s*NP_[\w.]*)+'
for test_str in test_strs:
matches = []
for match in re.findall(p, test_str):
matches.extend(re.findall(r'NP_[\w.]*\b', match))
print(matches)
Results:
['NP_dui', 'NP_fleeing', 'NP_evading_police', 'NP_possible_charges']
['NP_frog', 'NP_miss_piggy', 'NP_fozzie_bear', 'NP_old_favorites']

I have a regex for grabbing text on email for french number which is like this :
(?:(?:\+|00)33|0)\s*[1-9](?:[\s.-]*\d{2}){4}
Which work pretty well but if there is no phone number on an email it will grab part of the id of a Facebook page www.facebook.com/leboncoin-1565**0575204105**27 and then I have people trying to ring that nuumber :X
In case it's not clear and don't want it, I tried negative lookahead and behind but without any success
See problem at regex101.
Note that the phone number could be anywhere not necessary at the beginning of a line.
Use
(?:(?:\+|\b00)33|\b0)\s*[1-9](?:[\s.-]*\d{2}){4}\b
See regex proof.

I'm starving to understand the logic of regex let's say I got this string
1 SM-TEST S/M-BLEU, 25.00 EA 96.00
private void Window_Loaded(object sender, RoutedEventArgs e)
{
var test = ReadPdfFile("C:\\Users\\mducharme\\Desktop\\PO # 70882.pdf");
var result = Regex.Split(test, "\r\n|\r|\n");
foreach (var lines in result)
{
if (Regex.IsMatch(lines, #"^\d\s"))
{
string line = lines.ToString();
string pattern = #"^(\S+\s+\S+).*?,(?=\s*\d+\.\d+\b)";
string replacement = "$1";
string result2 = Regex.Replace(line, pattern, replacement);
System.Diagnostics.Debug.WriteLine(result2);
}
}
}
Each lines show a different value like the first one and so on
2 SM-BLABLA S-M-YELLOW, 50.00 EA 96.00...
In the end I want to show up in my MessageBox for the first value only
1 SM-TEST 25.00 EA 96.00
but the regex doesn't seems to do it's job compared to regex101 website code.
Thank you,
Use
^(\d+\s+(?:(?!\d+\.\d+\s+[xX]\s+\d+\.\d+)[A-Z0-9-])+).*?(?=\s\d+\.\d+\s)
See regex proof. Replace with $1.

Hi everyone I'm trying to select the content in between the second and third comma using regex
This is my content
INSERT INTO table (column1, column2, column3) VALUES ('Alejandro', 'dislike', '', 20, 'otro nombre')
INSERT INTO table (column1, column2, column3) VALUES ('Jando', 'like', '', 30, 'wtf')
As you can see between second and third comma are just single quotes '' and I want to selected them using regex because I need to modify like 5000 lines in sublime text 3, I hope you can help me, I tried with no success ,(.*){2} I know I'm wrong, I have no experience with regex
Note: No all time will be single quotes ''

Correct code:
"key1=val1;key2=val2;key3=val3" -- Correct as each pair is having ";" at the end except the last pair
Incorrect code:
"key1=val1;key2=val2; key3=val3;" -- Invalid as last pair is having ";" at the end
"key1=val1;;;key2=val2;;;key3=val3" -- Invalid as there are multiple ";" in the middle
I got the regex below from some old link in stackoverflow, but it is not working in the above case:
^(?:\s*\w+\s*=\s*[^;]*;)+$
You might use
^\w+\s*=\s*\w+(?:;\s*\w+\s*=\s*\w+)*$
Explanation
^ Start of string
\w+\s*=\s*\w+ Match 1+ word chars, = and 1+ word chars with optional whitespace chars
(?: Non capture group
;\s*\w+\s*=\s*\w+ Match ; and the same patter as mentioned above
)* Close the group and repeat 0+ times
$ End of string

With the doubled backslashes
^\\w+\\s*=\\s*\\w+(?:;\\s*\\w+\\s*=\\s*\\w+)*$

I find things like this much easier without regex. For eample with JavaScript:
function isValid(string) {
return string.split(/;/).map(e => e.split(/=/)).every(e => e.length === 2);
}
