  The program who push the data must provide the information about the
end of the data to the parser. You cannot guess that from the parser state
nor the XML data, that information must come from some context outside the
document. If you don't have that inforamtion availbale in your system you
are building it's a serious design flaw, basically it was designed without
understanding XML.

Well, I'm certainly not an XML expert, but here is what I've read from
the specs:


[1]     document           ::=          prolog element Misc*

        Misc       ::=          Comment | PI | S

      [Definition: There is exactly one element, called the root, or document
element, no part of which appears in the content of any other element.] For all
other elements, if the start-tag is in the content of another element, the
end-tag is in the content of the same element. More simply stated, the
elements, delimited by start- and end-tags, nest properly within each other.


So, if there is exactly one root element and if the client does not send
any Misc, I guess that detecting the end of the root element should
indicate that I received the whole request, right? Would redefining
endElementSAXFunc for such a purpose do the trick?
Or, what am I not understanding?
