This is exactly how the code appears in the editor (on different lines)
First i would use the main Beautify (tulip icon) to try and get all the files more 'normal' (there can be non-visible differences)
I do these as 2 separate S&R (because they are. The Right page and the Left page in a print book. )
Code:
<p class="calibre3"><i class="calibre1">Red Sky At Morning\s</i>\s*\d+</p>
I included (Guessed) the missing Opening P tag, change it as needed.
I used a s* (zero or more spaces) in some places where it appears a space MIGHT be in some cases
The second (other side) is similar
Code:
<p class="calibre3">\d+\s+<i class="calibre1">Melissa Good</i></p>
If this was code from an OCR, this S&R will almost never get all cases. Each of those will need to be recoded (common error) or hand deleted
