In your example code, you don't need any of the CFOUTPUT tags except the last one. CFXML lets you build an XML document object in memory. That said, I don't know if that'll affect your whitespace output. In my experience, I usually find it's easier just to get rid of whitespace at design time if I care about it, which I might in the case of XML. > And one more question: what exactly is returned to me if I omit the > toString conversion on the last line (toString(userXML)) ?

FMS uses ActionScript 1 still? Yikes! Anyway, CFXML creates an XML document object in memory. You can't just output one of those as a string; when you do, you get the funky syntax you saw. That is basically telling you that there's an object of type coldfusion.xml.XmlNodeList at a certain location in memory.
