How to replace a line, which has a specific text, with the content of a specific line?



  • You are right, however if you copy back what shows on your post it probably won’t work. I think the quotes have been nobbled by the markdown interpreter. We have all suffered from this issue and one way to resolve it is to put special characters around the code so the interpreter does NOT alter the characters at all.

    In the same way as you provided your 2nd example and I provided my regex, these can prevent the problem. Just inserting the code as you would text (as you did above) has (according to my test) affected the code.

    But good on you for trying it out. I got my code and removed the 2 (\d+) bits as I stated and then used your \1\4\5\4\7 and got the answer for when your file does NOT include line numbers.

  • It can be like that?

    ^(((.+)\R){5})(\d+)(.+\R)(?s)(.+)(?-s)^(..)(.+“name”: “noname”.+\R)(?s)(.+)
    \1\4\5\6\7\5\9

    Here I learn from the best.

    You are welcome to submit your proposed solution but I strongly suggest you need to insert those regexes within special codes so the markdown interpreter (the window you type the response in) does not adjust any characters that you type.

    You will note that my regex was in red text. This can be achieved by using the ` (grave accent character) around the regex. This key is generally top left on a full US keyboard, on the same key as the tilde character (~).
    The OP supplied their updated version without the (\d+) groups just as text, much like you and it was affected.

    Mine:
    (?-s)^(((.+)?\R){5})(\d+)(.+\R)(?s)(.+?)(?-s)^((\d+).+"name": "noname".+\R)(?s)(.+)
    Theirs:
    (?-s)^(((.+)?\R){5})(.+\R)(?s)(.+?)(?-s)^(.+“name”: “noname”.+\R)(?s)(.+)
    

    Look closely at the quotes in each regex, notice any difference? This is one of many changes that can occur if you don’t add the codes around text you do NOT want altered.

    Also, once typing a response in the window, you have other commands available. You should see a </> button above the window, select this first when entering code text, note this is what I did above rather than use the grave character. It is also useful for when inserting example text so that others may copy the data “unchanged”.

  • Nobody uses such quotation marks here

    “name”: “noname”

    `red`
    

    red
    Red doesn’t work everywhere



  • @Pan-Jan

    It seems that you feel offended when someone gives you an well-intentioned advice.
    Why is that?
    If I copy your regex solution, I get, for example “name” instead of "name" and thus your solution is corrupted.
    If, as @TerryR recommends, you wrap your solution in ` or use a code tag, this will not happen.
    What is the problem here?



  • @Ekopalypse
    Don’t overdo it.
    I don’t feel offended at all.
    This is due to the short texts, but it is best to translate them.

    Only such quotation marks are correct

    "name": "noname"
    

    If I copy

    First, that’s false. It is perfectly reasonable for a question to include literal curly-quotes / smart-quotes in the question and/or answer.

    But moving on to your general thought, which seems to be “people usually don’t have text with curly quotes, so everyone – whether the person asking the question or the person answering – should somehow know that they need to mentally convert curly quotes into ASCII quotes”:

    let’s try out a couple scenarios. There will be three people in these scenarios: @QuestionAsker, @NoRedAnswer, and @YesRedAnswer.

    -----

    scenario 1, with @NoRedAnswer

    @QuestionAsker says:

    I have text, and want to strip out anything that’s inside quotes with no spaces:

    This will remove quotes: "NoSpaces"
    This will keep quotes: "This has spaces"
    

    After running search-and-replace, I want

    This will remove quotes: NoSpaces
    This will keep quotes: "This has spaces"
    

    @NoRedAnswer replies:

    Use the search term “(\w*)” and replace with $1

    @QuestionAsker says:

    Sorry, that didn’t work. I tried both (\w*) like you said, and tried “(\w*)”, but neither of them changed my text any.

    The @QuestionAsker didn’t understand the answer, because @NoRedAnswer didn’t format the answer using the forum’s formatting tools. This caused confusion and delay.

    scenario 2: same circumstance, but @YesRedAnswer

    @QuestionAsker says:

    I have text, and want to strip out anything that’s inside quotes with no spaces:

    This will remove quotes: "NoSpaces"
    This will keep quotes: "This has spaces"
    

    After running search-and-replace, I want

    This will remove quotes: NoSpaces
    This will keep quotes: "This has spaces"
    

    @YesRedAnswer replies:

    Use the search term "(\w*)" and replace with $1, with Search Mode set to regular expression

    @QuestionAsker says:

    Great, @YesRedAnswer! That worked on the first try! Thanks for your help. ++@YesRedAnswer

    -----

    As you should be able to see, the answer that did use red text for the regular expression was much more helpful, even though both people who answered came up with the same working regex.

    In the end, it’s your choice how to answer (or ask) questions in this forum. But you can choose to (1) make it easier for the others to understand you, or you can choose to (2) skip the red text and black text boxes, and make the person you’re helping (or the person you’re asking) try to figure out what you really meant, and probably get it wrong. We are just advising that you use style (1) rather than (2).



  • Got it … don’t put patterns in quotation marks

    Only such quotation marks are correct “”
    If necessary, use only such quotation marks “”

    But there is something I don’t understand.
    Maybe it’s the translation’s fault.

    “in quotation marks”

    I get it this way … you should remove the quotes:

    "ABC"
    

    and will be:

    ""

    Unfortunately, you completely misunderstood. It appears the language barrier is too big.

    I will say it one more time. I will try to use short sentences. Hopefully your translator will understand.

    • Put regex inside ` marks to make them red. This makes regex display as literal characters for the forum, without being edited.
    • My example had quote marks as part of the regex, which is valid.
    • Always use the quote marks you mean.
