The basic answer to your question is no. You can't 'reach into' a tag
and grab a variable. However, it sounds to me like you are saying that
you need a way for the custom tag to return a dynamic variable name.
A good example of why this is needed: Imagine a custom tag that returns
a variable to caller scope called Result. If you wanted to do this:
<cf_tag x=1>
<cf_tag x=2>
You would 'lose' the Result variable when you called cf_tag the second
time.
There is an easy way around this. Simply tell the tag to return a
dynamic variable name. Add an attribute to your custom tag called r_Var
(or whatever you want). Then, at the end of your tag, do:
<cfset "caller.#attributes.r_Var#" = whatever>
Or
<cfset setVariable("caller.#attributes.r_Var#",whatever)>
Then you can do:
<cf_tag x=1 r_Var="result1">
<cf_tag x=2 r_Var="result2">
<cfoutput>#result1# and #result2#</cfoutput>
If you use cfparam for r_Var, you can even add validation that a valid
variable name was passed - just use type="variableName"
