I generally use regular expression search and replace...
To take your example (replaced your weird characters with the quotes for readability):
Code:
<div style="margin-top: 6"/>
<div style="text-indent: 1em"><font size="3">"What I was going to ask your boss, Charley, is if there is some good reason you can't go to Buenos Aires right now."</font></div>
<div style="margin-top: 6"/>
in my style:
.emptyLine { margin-top: 6em; }
p { text-indent: 1em; font-size: normal; }
<div style="margin-top: 6" /> would be replaced with <div class="emptyLine" />
<div style="text-indent: 1em"><font size="3"> would be replaced with <p>
</font></div> would be replaced by </p>
I generally start with headers and other exceptions (there are less headers than paragraphs, generally
). Then I create an epub out of it, check it, fix any errors and repeat the checking process until it's clean.
