Re: Automating an atypical search & replace

I'm reformatting some HTML files containing chapters of the KJV Bible.
My source follows the practice of italicizing some words.
I find italics distracting.
 
These occurrences are consistently of the form

I wish to delete "<span class='add'>" and *ASSOCIATED* "</span>".
Obviously it would not be wise to fully automate the action.
I wish to find all occurrences of <span
class='add'>arbitrary_text</span> an manually confirm the edit.
 
In general, is it feasible?

Yes, sure.

Some remarks...
I would use Regular Expressions (RE) for that task.
If <span> sections can be nested in your HTML source then you
cannot do that with plain RE processors.
Since you want to inspect each <span> pattern individually it's
not clear what you mean by "automate" (which I'd interpret as
running a batch job to do the process).
Actually you seem to want a sequential find + replace-or-skip.

In Vim I'd search for the "<span ..." pattern and then delete
to the next "</span>" pattern. (Assuming no nested <span>.)
Rinse repeat.
That could be (for example) the commands [case 1]

  /<span class='add'>
  d/<\/span>df>

If there's no other <...> inside the span-sections you could
simplify that to [case 2]

  /<span class='add'>
  d2f>

with the opportunity to repeat those search+delete commands
by simply typing  n.  for every match, like  n.n.n.n.  or if
you want to skip some like, e.g.,   n.nnnn.n.nnn.n

With  n  you get to the next span pattern and  .  repeats the
last command.

In [case 1] the repeat isn't possible since we have two delete
operations  d/<\/span>  and  df>  , but here you can define
macros to trigger the command by a keystroke or just use the
recording function to repeat the once recorded commands.

Sounds complicated? - Maybe. - But if we know your exact data
format we can provide the best command sequence for Vim for
most easy use.

Can KDE's Kate do it?

Don't know.
