Counting characters in an output

[rosn459]

I have an output that contains hyphens. I could have an instance of one hyphen or more than one.

EX:
AK-AL-AB
MO-MS
KS

How would I count the number of hyphens in my output? I know what I want to do once I get the correct number of hyphens.

how about using ListLen like so:

<cfoutput>
<cfset stringToSearch = "ab-cd-ef">
<cfset numofoccurances = ListLen(#stringToSearch#, '-')>
#Variables.numofoccurances#
</cfoutput>

will output 3, not the number of hyphens but the number of abbreviations.

Good Job NorthStar, that's the best way to do it..

But as has been discussed in thread232-833069 there's some issue with the above code when delimiters repeat..

If you want to count hyphens and you can be certain you'll never have two or more hyphens in a row, you'll be fine.

But if you can't be certain of that.. Here's your number of hyphens

<cfset hyphnum=len(string)-len(replace(string,"-","","ALL"))>
