Answer 3

Is there any way to fix this?

There's nothing to fix - the HTML is perfectly valid and functional.

If your issue is the size of request, use gzip encoding.

If your issue is reading the source for debugging/etc, use developer tools such as Firebug/etc.

However, general things you should be doing to improve maintainability (which at the same time also reduces whitespace output) are:

1) Move anything that isn't display logic out of your views.

2) Convert display logic to functions and custom tags as appropriate, which both make it easier to prevent/control output.

To prevent unwanted content being output, you can:

• Wrap the entire section in cfsilent, to ensure nothing gets output.

• Enable enablecfoutputonly attribute of cfsetting then only use cfoutput around things you want to be output.

• Always set output=false on component and function tags.

• When you want to selectively output some text, wrap non-tag non-output segments in CFML comments <!---...---> (e.g. useful for preventing newline output in custom tags)

(I never bother with cfprocessingdirective, everything mentioned above solves the issues better.)
