I have not mastered how to do multi-line regex yet with the current engine.
I want to strip all but one layer of all blockquote nestings e.g,
go from 2 or more level deep like this
<blockquote class="a">
<blockquote class="a">
<blockquote class="a">
<p class="text">some text here</p>
</blockquote>
</blockquote>
</blockquote>
and reduce it to
<blockquote class="a">
<p class="text">some text here</p>
</blockquote>
i figure that the regex only needs to shrink 2 layers to 1, then if it is run multiple times it will progressively strip layers until only single layers remain.
assume also that I can by inspection insert the appropriate class names into the regex
I tried find
<blockquote class="calibre11">\s*<blockquote class="calibre11">(.*)</blockquote>\s*</blockquote>
with a suitable replace all, but it did not fully automate.( it seemed to only do one instance, evenwhen I said replace all) ; also I was not sure if I needed to tick any options e.g. Dotall
