another way is to use this custom tag: StripWhiteSpace.cfm

I'm not sure who originally wrote it, but it works well.
If you place it in the same directory as the calling template you can call it
like this:
<CF_StripWhitespace StrengthMode="maximum">
<!--- your code goes here --->
</CF_StripWhitespace>
