Extra white-space after page proccess

Question

I am trying to suppress white-spaces after the page is
processed.
Usually it doesn't bother me, but it does bother javascript.
Explanation:
1. I am sending an xmlhttp request to coldfusion to process.
2. Coldfusion runs a stored procedure on an oracle database
that returns the results as XML.
3. Coldfusion returns the XML back to the client:
<cfoutput>#XmlParse(ajaxXML)#</cfoutput>.
4. The client (Javascript) runs the function that handle the
data and returns an error because: "
xml declaration not at start of external entity".
I have tried using cfsetting with the attribute:
enablecfoutputonly="yes", but still the result is the same.
Any idea or lead in the right direction would be greatly
appreciated.

Answer 1

The XML that the DB returns, looks like this:
<?xml version="1.0"?>
<rowset>
<row>
<column_name>value</column_name>
<column_name>value</column_name>
</row>
</rowset>
After playing with code for a while now, I believe that the
problem is not with the returned XML.
The page that runs the SP is the page that call the SP. What
means that the white-spaces are the code that the Coldfusion engine
has already processed (although, the condition that checks whether
the form variable that Ajax request, exist. Is the first thing on
the page). to my understanding, the returned XML should be at the
top of the page.
I hope that I was clear enough.
Thank you.
