This will not be possible. Basically, I have a Hashtable of objects
that each have a property that is an XML string. I want to iterate
over the Hastable's values and pass the XML string from each object to
a custom tag I have to render the XML with an XSL template.

Hmm, this seems like it could end up being a problem for many
people. I just looked at the code. I am not sure what clearBody() does
(I'm new to Struts), but if I understand you correctly, are you saying
that Custom tags, when invoked inside the iterate tag, may or may not
behave properly? I would think that tags should always behave in a
"context free" way just like any code in any language does. In Java,
you would barf if you saw a function that behaved differently based on
the the state of the caller. Imaging if suddenly Object.toString()
broke because you are calling it inside of a method that "did not
intend Object.toString() to be called withing its context". In this
case, I implemented my Tag after the iterate tag was implemented and
so MAYBE I can find a workaround. However, there might be many tags
out there that work perfectly but may break if used inside the iterate
tag.
Do you think there is a way for the struts team to fix this or am I
missing something and you do not think this is a bug.
thanks for you reply
