coldfusion - structDelete doesn't affect the shallow copy? -

I was playing around error because I tried to create an error using a large XML document object.

  & lt; Cfset XMLByRef = variables.parsedXML.XMLRootElement.XMLChildElement & gt; & Lt; Cfset structDelete (variables.parsedXML, "XMLRootElement") & gt; & Lt; Cfset startxML shortlove = getTickCount () & gt; & Lt; Cfloop = "1" from = "#arrayLen (variables.XMLByRef) #" index = "variables.i" & gt; & Lt; Cfoutput & gt; # Variables.XMLByRef [variable. I] .id.xmltext # & lt; / Cfoutput & gt; & Lt; Br / & gt; & Lt; / Cfloop & gt; & Lt; Cfset stopXML short loop = matching () & gt;  

I hope to get an error because I removed the structure that I was referring to.

From LiveDocs:

variable assignment - creates an additional reference, or alias for the structure. Any change in data uses a variable name changes the structure that you access using other variable names. This technique is useful when you want to add a local variable to another location or otherwise want to change the scope without any variables, instead of

  & lt; Cfdump var = "#variables #" & gt; ;  

Shows nothing in the structure, with the value of XMLRootElement just parsedXML.xmlRoot.xmlName. I too

Structure Claire for both.

Can someone understand my flawed logic? Thank you.
