OK, with help from Roland Küffner and Christopher Stone, I've been able to
create the script I need. More on that in a bit.
There have been a number of suggestions that using find/replace with grep
should work. That only works well if there are no nested spans (with inner
spans that I want to keep ... i.e. spans with class attributes as opposed to
span elements with no attributes). And matching beginning and closing tags is
difficult in a nested element scenario. So, a script seems like the safest
approach.
So here is what I did. First, I started with the script from Roland that
selected the outer tags of a balanced tag selection. I'll repeat that original
script here:
tell application "BBEdit"
if (balance tags) then
set x to characterOffset of selection
set y to x + (length of selection)
inside tag start range (x - 2) end range (x - 2)
set tagLength to (end_offset of tag of result) - (start_offset
of tag of result)
set x to x - tagLength - 1
inside tag start range (y + 1) end range (y + 1)
set tagLength to (end_offset of tag of result) - (start_offset
of tag of result)
set y to y + tagLength
select characters x thru y of window 1
else
beep -- script beeps if it could not create an initial balance
end if
end tell
Then I modified it to remove the outer tags:
tell application "BBEdit"
if (balance tags) then
set x to characterOffset of selection
set y to x + (length of selection)
inside tag start range (x - 2) end range (x - 2)
set tagLength to (end_offset of tag of result) - (start_offset
of tag of result)
set xOpen to x - tagLength - 1
set lenOpen to tagLength
set yOpen to xOpen + lenOpen
inside tag start range (y + 1) end range (y + 1)
set tagLength to (end_offset of tag of result) - (start_offset
of tag of result)
set xClose to y
set lenClose to tagLength
set yClose to xClose + lenClose
-- set insertion point before character xClose
tell window 1 to select (characters xClose thru yClose)
tell window 1 to delete selection
tell window 1 to select (characters xOpen thru yOpen)
tell window 1 to delete selection
else
beep -- script beeps if it could not create an initial balance
end if
end tell
Then I made it specific to a <span> element:
tell application "BBEdit"
set origInsPt to characterOffset of selection
if (balance tags) then
set x to characterOffset of selection
set y to x + (length of selection)
inside tag start range (x - 2) end range (x - 2)
set t to tag of result
if ("span" is equal to name of t) then
set tagLength to (end_offset of t) - (start_offset of t)
set xOpen to x - tagLength - 1
set lenOpen to tagLength
set yOpen to xOpen + lenOpen
inside tag start range (y + 1) end range (y + 1)
set tagLength to (end_offset of tag of result) -
(start_offset of tag of result)
set xClose to y
set lenClose to tagLength
set yClose to xClose + lenClose
-- set insertion point before character xClose
tell window 1 to select (characters xClose thru yClose)
tell window 1 to delete selection
tell window 1 to select (characters xOpen thru yOpen)
tell window 1 to delete selection
else
tell window 1 to select (insertion point before
character origInsPt)
beep -- script beeps if it outer element is not <span/>
end if
else
beep -- script beeps if it could not create an initial balance
end if
end tell
Then I used a script from Chris to create the wrapper code to find an empty
span element and do some processing with it; I added a loop that repeated until
there were no more empty <span> elements remaining:
tell application "BBEdit"
set keepGoing to true
repeat while keepGoing = true
tell text of window 1
set fndRsltStart to find "<span>" options ¬
{search mode:grep, case sensitive:false,
starting at top:true} with selecting match
end tell
set keepGoing to found of fndRsltStart
if keepGoing = true then
set z to characterOffset of selection
tell window 1 to select insertion point before
character (z + 2)
if (balance tags) then
set x to characterOffset of selection
set y to x + (length of selection)
inside tag start range (x - 2) end range (x - 2)
set t to tag of result
if ("span" is equal to name of t) then
set tagLength to (end_offset of t) -
(start_offset of t)
set xOpen to x - tagLength - 1
set lenOpen to tagLength
set yOpen to xOpen + lenOpen
inside tag start range (y + 1) end
range (y + 1)
set tagLength to (end_offset of tag of
result) - (start_offset of tag of result)
set xClose to y
set lenClose to tagLength
set yClose to xClose + lenClose
-- now remove the closing and opening
element tags
tell window 1 to select (characters
xClose thru yClose)
tell window 1 to delete selection
tell window 1 to select (characters
xOpen thru yOpen)
tell window 1 to delete selection
else
tell window 1 to select (insertion
point before character origInsPt)
end if
end if
end if
end repeat
end tell
That is it!! I assigned a shortcut key to that script and am ripping through
the nearly 100 files that need to be cleaned up. Very cool.
Now, there could be more to be done here. I probably need an "on error" handler
(Chris had one, but I didn't keep it). And I might need to be referencing the
current document with something other than "window 1" ... or maybe check that
window 1 is actually a text window. And I might want a "beep" if the script did
no work.
I'll probably add some of that clean up later (I anticipate need this script
quite a bit). For now, I'm quite happy -- lots of tedium avoided.
Thanks to everyone who contributed suggestions. All were appreciated.
Awesome response folks!
