I think it is nice.

Dear CFDUMP, why don’t you HtmlEditFormat() your output!?

Today I finally tried using <cfxml> for the first time.  However, when I tried using an element from the xml, it always have an empty space in front. Hmm…

<cfoutput>’#value#’</cfoutput>

At first I thought it is some CF quirks, so I tried

<cfprocessingdirective suppressWhiteSpace=”true”>

but the white space is still there somehow…

Then I tried putting a Trim() around the value, but the white space still there!!! What!?

Finally, I highlight the non-removable space, right-click, “view selection source” in Firefox, and THERE IT IS!

‘<myElement>xxx</myElement>’

Lesson learned.  I needed to reference myElement.XmlText to get ‘xxx’.

If <cfdump> does a HtmlEditFormat() for the browser output… I guess I’ll have nothing to blog about today.  :)
