regex: find two different strings on two consecutive lines

[Vasile Caraus]

hello. I have this kind of strings, on two consecutive lines. Before and after string, on every line, should be empty:

     <p>&nbsp;</p>  
    <p class="text_obisnuit">

So, I need to find all those 2 consecutive lines, and replace it with:

     <br><br>  
    <p class="text_obisnuit">

it would have been a simple search and replace if those strings had been positions in the same place, but may be disturbed by spaces before and after. This is why I need a regex.

My solution, is not too good :(

SEARCH: \S\s(?s)(<p>&nbsp;</p>)\S\s|\n\r|\S\s(?s)(<p class="text_obisnuit">)\S\s
REPLACE BY: <br><br>\n\2

so am I correct to assume that you want to change the tags AND
delete the spaces as well?
If so, what about this (\h*<p>&nbsp;</p>)\h*\R\h*(<p class="text_obisnuit">) ?

[Vasile Caraus]

yes, Eko, your regex is great !! I write it here again with the replace:

SEARCH: (\h*<p>&nbsp;</p>)\h*\R\h*(<p class="text_obisnuit">)
REPLACE BY: <br><br>\n\2

Thank you very much

Hello, @vasile-caraus, @eko-palypse and All,

Here is, below, a similar regex S/R, with a look-ahead structure, which, also, preserves the indentation of the two lines, involved !

So assuming the sample text, below :

    <p>&nbsp;</p>  
    <p class="text_obisnuit">

        <p>&nbsp;</p>  
            <p class="text_OTHER_1">

<p>&nbsp;</p>  
      <p class="text_obisnuit">

  <p>&nbsp;</p>  
<p class="text_OTHER_2">

        <p>&nbsp;</p>  
    <p class="text_obisnuit">

If we use :

SEARCH (\h*)<p>&nbsp;</p>(?=\h*\R\h*<p class="text_obisnuit">)

REPLACE \1<br><br>

the above text becomes :

    <br><br>  
    <p class="text_obisnuit">

        <p>&nbsp;</p>  
            <p class="text_OTHER_1">

<br><br>  
      <p class="text_obisnuit">

  <p>&nbsp;</p>  
<p class="text_OTHER_2">

        <br><br>  
    <p class="text_obisnuit">

---

With the previous regex S/R, we would have obtained :

<br><br>
<p class="text_obisnuit">

        <p>&nbsp;</p>  
            <p class="text_OTHER_1">

<br><br>
<p class="text_obisnuit">

  <p>&nbsp;</p>  
<p class="text_OTHER_2">

<br><br>
<p class="text_obisnuit">

Note, also, that this new regex S/R works, whatever the line endings ( \r\n for me and \n for you )

Best regards,
