RE: number of occurrences in a string.
It would have to do the search more than twice, it woudl have to do every possible case combination of either the string or the RE. I suspect that internally it just does a LOWER or UPPER on both the RE and the string. -Original Message- From: Philip Arnold [mailto:[EMAIL PROTECTED] Sent: Friday, October 17, 2003 8:15 AM To: CF-Talk Subject: RE: number of occurrences in a string.

RE: number of occurrences in a string.
\b only on cfmx. As I said before, the array created will give you the number of subexpressions (2: the entire regexp and the subexpr (beg)) of the first match. In cf you need a loop. Try putting 3 beg's in your string.

RE: number of occurrences in a string.
I always assumed it said, match A or a, not search twice. I guess it depends on what is happening at the lowest level. I've never seen any recommendations in the past to not use findNoCase or reFindNocase (or etc). [Todays Threads] [This Message] [Subscription] [Fast Unsubscribe] [User Settings]

Nope, I stand corrected, you still need to loop. But \b may be better than [^a-z]+. [Todays Threads] [This Message] [Subscription] [Fast Unsubscribe] [User Settings]

RE: number of occurrences in a string.
the for loop isn't right: 1. if it doesn't find a match, it continues looping 2. if there is a match, start will become greater than the string length 3. the word is not escaped for special chars in regexp 4. when the new start position is set, it isn't set to the right place (should be +Len(word)+2, but this isn't a problem, it is just not efficient). Look at the code I posted, I think it will be more efficient. Maybe the 4th attribute of REFindNoCase can be dropped and the length to add can be calculated from the original word before escaping. -Oorspronkelijk bericht- Van: Raymond Camden [mailto:[EMAIL PROTECTED] Verzonden: vr 17/10/2003 15:52 Aan: CF-Talk CC: Onderwerp: RE: number of occurrences in a string.

I was doing _javascript_ when I posted this. Obviously the first element in the array has index 1 in CF. So replace [0] by [1] in my code.

Does anybody have answer for this .When I use cflib function wordinstance()
sometimes CPU usage will max out ,it reaches its max to 100%. It takes a
good amount of time to open the page. This is the only function which give
me correct results. My concern is when the site will generate good traffic
it will choke the server. I am not sure why. Any help or suggestions are

RE: number of occurrences in a string.
What you are returning here is the number if subexpressions of the first matching word (will always be 2), NOT the wordcount. To count the number of words, you NEED to loop. Also, you will need to escape the word for regular expressions (escape chars like \$^([ and so on). Finally, you probably want to do a REFindNoCase.
Look at CountIt (http://www.cflib.org/udf.cfm?ID=304) on cflib.org, but use REFindNoCase instead of FindNoCase with the regexp in the code. There is an escape function for RegExp on cflib too.

RE: number of occurrences in a string.
> Will this work in CF5.0 ?
*Now* he says... No, it's MX only. But I _think_ this should do it
(and work on MX too):
function wordcount(word, line) {
var wordarray = refind("[^[:alpha:]](#word#)[^[:alpha:]]", line, 1,
TRUE)>
if (NOT wordarray.len[1]) { return 0; }
return arraylen(wordarray.len);
}
No promises on it working though - only MX here so can't test it.
