Repetitive white spaces in string

[d.acha]

I want to prevent if visitor type more than 1 white space between two words.
For example (I will use underscore "_" instead of white space " " here,
because You cannot see repetitive white spaces, only in source):
let's say, the string visitor will type in the input form field is:
"macromedia___coldfusion_mx_____7"
I want to replace all needless white spaces (or underscores here) and I want
to get following string "macromedia_coldfusion_mx_7" - between two words I want
to have only one white space

have you any ideas?
regards,
d.acha

Use REReplace

#reReplace(testString,"\s+"," ","All")#

This a regular expression replace.
The first param is the string that the extra white space is to be stripped
from.
The second param is a regular expression which you are looking to replace.
The regular expression "\s+" means one or more white space characters.
The third param is the string that you will be putting in place of the
previous.
The fourth param is optional, "All" indicates that you would like to replace
all instances of the reg expression. The default for this param is "One" which
will replace only the first occurance.

The code below will allow you to see it in action.
<cfset testString = "my cold fusion server">
<pre>
#testString#
#reReplace(testString,"\s+"," ","All")#
</pre>

Best of Luck,

thanks nancy,

that's that!

Additionally, I have surrounded Your code with one Trim function and I have
exactly what I have meant.
Trim(reReplace(testString,"\s+"," ","All"))
Bye the way, You have exactly typed what I have asked, but I need that Trim
more.

Thanks a lot
