Aha! Of course. I should have thought of that. Mark pointed out the same
thing. (And yes, my brief test had the metadata in the third paragraph.)
I'll try his handler when I get back to my Mac. If my guess is correct, the
search won't take any measurable time at all and the primary delay will be
loading the htmltext into a variable.
You guys are great.

the styledArray does not include the returns at the end of a line. You have
to add them if you address chars/codeUnits of the whole text. Initializing
tTotalChars with -1 lets you add 1 to tTotalChars in each iterations of the
outer repeat loop. -1 because the first line is not has no preceding return.
Also add 1 to calculate tStartChar otherwise you point to the last char of
preceding run.
put -1 into tTotalChars -- note -1
put 0 into tStartChar
repeat with i = 1 to the number of elements in tDataA
add 1 to tTotalChars -- account for returns
put tDataA[i]["runs"] into tRunsA
-- note add 1
put tTotalChars - len(tRunA["text"]) +1 into tStartChar -- mark char 1 of
target
Additionally in your implementation if the target run with the metadata you
look for is the last run of the array nothing is returned.
Kind regards
Bernd
