My test on a 200-page document with one object per page, where the object on every third page had a key inserted showed that the first snippet ran more twice as fast as the second (about 3 seconds to 7 or eight seconds -- still both usably fast):
#1:
tell application "Adobe InDesign CS2"
tell active document
set allPageItems to all page items
set keyRefs to {}
tell all page items
set keyList to extract label key "SOME_KEY"
end tell
repeat with i from 1 to (count items of keyList)
if item i of keyList is not "" then
copy item i of allPageItems to end of keyRefs
end if
end repeat
return keyRefs
end tell
end tell
#2:
tell application "Adobe InDesign CS2"
tell active document
set itemList to {}
set itemCount to count items of all page items
set pageItems to all page items
repeat with i from 1 to itemCount
tell item i of pageItems
set extractedLabel to extract label key "SOME_KEY"
try
if extractedLabel is not "" then
set end of itemList to object reference
end if
end try
end tell
end repeat
return itemList
end tell
end tell
