Regex: why is numeric capturing after negative lookahead not working?

Asked 2022-Mar-15 at 02:09

(.)(?!\1)\1

I think this should match any character [c], followed by any character that is not [c], then followed by [c] again.

like 'aba', 'xyx'

But online regexr validator is telling me im wrong. Where is the issue?

Thanks in advance.

ANSWER

Answered 2022-Mar-15 at 02:08

You were correctly checking if the second character isn't the same as the first (group), but you forgot to allow a match on the second character otherwise.

(.)(?!\1).\1

If you want to also want the matches to be 3 characters only,

(?=.{3}$)(.)(?!\1).\1

QUESTION

How do I "not" select first character in a regex pattern?

Asked 2021-Dec-25 at 10:38

I am a RegEx beginner and trying to identify the endings of different statements in sms. See screenshot below.

How can I avoid selecting the next letter following by a full-stop that indicates ending of a statement.

Note that some statements have <.> while some have <.>

Regex used: r"\. ?[\D]"

Sample SMS: - I want to select just the full-stop and space if any.

What you're looking for is a look-ahead group. Whether you make that a positive look-ahead and use the negated character set \D or a negative look-ahead with the character set \d doesn't really matter- I'll outline both below:

QUESTION

Match "After" if it doesn't have an an -ing word after it

Asked 2021-Oct-23 at 07:37

I want to match After if there isn't an -ing word after it (and before a comma). So there shouldn't be an -ing word between After and the comma.

Desired match (bold):

After sitting down, he began to talk.

After finally sitting down, he began to talk.

After he sat down, he began to talk.

I thought this regex would do it:

ANSWER

Answered 2021-Oct-23 at 06:12

Try this regex

Matches only sentence from After and a comma, where there's no word with -ing after the wo

Just a lazy quantifier to the .+ (which instead of \w+in your regex) does the trick

\bAfter (?!.+?ing).*?,

(And also a lazy quantifier after the second .*, just in case if there's 2 commas in the same sentence)

ANSWER

Answered 2021-Oct-19 at 15:24

This pattern ^.*\[.*(?!\]).*$ matches [ and the directly following .* will match the rest of the line.

Then at the end of the line it will assert not ] directly to the right, which is true because it already is at the end of the line. Then the .* is optional and it can assert the end of the string.

So it will match any whole line that has at least a single [

If you want to match pairs of opening till closing square brackets [...] and not allow any brackets inside it, or single brackets outside of it and matching at least a single pair, you can repeat 1 or more times matching pairs surrounded by optional chars other than square brackets.

Regex: Match multiple timestamps in a string

Asked 2021-Oct-15 at 06:29

I have a text file that line by line details a timestamp at the very start, and may contain other timestamps in between. The first timestamp is always enclosed in [], and the ones in the middle of the line are always enclosed in <>. The goal is to create a regex pattern that can create groups for the timestamp and the text that follows it. I'm pretty new to regex, and I'm having a hard time with it. The text would look like this:

ANSWER

Answered 2021-Oct-15 at 06:29

Going with pure regexp splitting I'd use the following. The regexp matches < or [ followed by your number pattern, then > or ] for the timestamp. For the content it takes everything until the first < and [ occurres.

RegEx: Get multiline LDAP entry

Asked 2021-Sep-29 at 14:55

I'm trying to capture an entire LDAP entry from dn:.+ to the entry's last line, but stopping at last line before next entry, e.g., \n#entry-id: 8266. My trial and error using egrep is getting absolutely nowhere. NOTE: I'm using exported ldif files where the data resides, fwiw.

Closest I've come is with egrep "dn: cn=name,ou=People,dc=example,dc=com.+.|\n*.+\n" but no output on terminal. I've tested the actual regex on regexr.com. I understand that is a completey different env.

egrep uses extended regexp (equivalent to grep -E). Prefer grep -P (perl regexp) instead.
The -z flag makes your regex multiline:
