man, i was outputting a TAB file and i kept manually removing whitespace until i got fed up with it and found this article. the first option under server settings solved this for me. now the output tab-delimeted file has no whitespace generated from code. thanks again.

@mark I haven’t tried the servlet filter on ColdFusion 9, but perhaps the JAR file conflicts with later versions of libraries used within ColdFusion.

Why do I get an error when trying this? I’m using CF9. I get something like the application is not configured to run your request.

will reset the content loaded by a page to blank… I usually put at the top of my onRequestStart() in application.cfm. Just for those who don't have the ATM to mess with a servlet install and need a quick fix.

Oops, for 1) I meant for my entire app

Of all the CF methods you mention, I have found the following best practice to be most useful:
1) for my entire app (put it in application.cfc onRequest() or at the top of every page or something).
2) ALWAYS wrap my output in a cfoutput tag.
This has simplified my development a lot and I have no white space issues any longer. The separation of concerns (code, output) has helped simplify my file structure; it is very clear where html output is happening and where it is not. I simply use a cfloop inside a cfoutput if I want to output a query. It also avoids the unpleasant issue of white-space trimmers mucking with my page and causing it to break (which happens rarely, but when it does can be a pain to fix).

To remove empty lines from an xml:

ReReplace(xml, “[\s]+[#Chr(13)##Chr(10)#]+”, “#Chr(10)#”, “ALL”)

Nice. Works like a charm.

Thanks!

Thanks, for the info saved me about a trimmed about a 1/6th off the download. I was going to go in manually and try to use the traditional methods you mentioned but this is much easier.

Thanks!
