Paste a new line of code after every instance of an existing line



  • That’s pretty much it…

    I have a line that is:
    <span>old text here</span>

    And I want to paste a new line:
    <span>old text here</span>

    After each occurrence of the old line.



  • @berrmirt ,

    Your example shows adding the same text after each occurrence of the old. I am not sure that it what you meant.

    Assuming for the moment that your original text is:

    <span>old text here</span>
    <span>something else</span>
    <span>old text here</span>
    <span>something else</span>
    <span>old text here</span>
    <span>something else</span>
    <span>old text here</span>
    <span>something else</span>
    <span>old text here</span>
    <span>something else</span>
    

    If you use

    • find = <span>old text here</span>(\R)
    • replace = $0<span>new text here</span>$1
    • search mode = regular expression

    it will become:

    <span>old text here</span>
    <span>new text here</span>
    <span>something else</span>
    <span>old text here</span>
    <span>new text here</span>
    <span>something else</span>
    <span>old text here</span>
    <span>new text here</span>
    <span>something else</span>
    <span>old text here</span>
    <span>new text here</span>
    <span>something else</span>
    <span>old text here</span>
    <span>new text here</span>
    <span>something else</span>
    

    Is that what you wanted?

    explanation:

    • in the find, most is literal text, except (\R), which says “match any newline (CR, LF, or CRLF), and save that end-of-line-type into$1`”
    • in the replace:
      • $0 = the whole matched line from FIND, including newline
      • then the new plaintext
      • $1 = make a copy of the newline matched, so that this new line will match the same EOL-type as the matched line

    FYI: if you have further regex (search-and-replaceneeds, study this FAQ and the documentation it points to. Before asking a new regex question, understand that for future requests, many of us will expect you to show what data you have (exactly), what data you want (exactly), what regex you already tried (to show that you’re showing effort), why you thought that regex would work (to prove it wasn’t just something randomly typed), and what data you’re getting with an explanation of why that result is wrong. When you show that effort, you’ll see us bend over backward to get things working for you. If you need help formatting the data so that the forum doesn’t mangle it (so that it shows “exactly”, as I said earlier), see this help-with-markdown post, where @Scott-Sumner gives a great summary of how to use Markdown for this forum’s needs.
    Please note that for all “regex” queries – or queries where you want help “matching” or “marking” or “bookmarking” a certain pattern, which amounts to the same thing – it is best if you are explicit about what needs to match, and what shouldn’t match, and have multiple examples of both in your example dataset. Often, what shouldn’t match helps define the regular expression as much or more than what should match.



  • Thank you, sir, that’s exactly what I was looking for!

    Also, I appreciate the detailed explanation, it was very helpful.

    Further, I was able to use your link to determine that I needed to add "(\t\t\t) to my replace expression to align the ‘new’ line with the old code line.
