i wanted to tweak the layout of a short story (a library book loan- unlocked just for read-once layout tweaking)
It was using a lot constructs like this for spacing.
<p class"something"> </p>
(where the the gap seemed to be a simple space)
but I could not get the regex engine to find any of those lines no matter how I tweaked the options
It could find the 1st part ok, the bit before the "space" i.e. it could find
<p class"something">
but that was all. & useless as every line in the story starts like that!
maybe it was some weird "space" character, but when I opened with sigil instead , pasted in the offending line & hit replace all , it zapped them , no problems.
so is it a bug or is it a character issue ?
as it is an unconverted retail epub loan, I would not expect any weird characters to be in it
NB I did what i usually do in such cases, I coped & pasted the offending line into the regex find box, so any strange character should have copied over.
I think it more likely to be a bug in book editor regex
