Summary: 1.95.2 Reuses Buffer if isFinal != 0
Initial Comment:
In expat 1.95.2 (the latest version for which a
FreeBSD package is available), calling
XML_ParseBuffer() or XML_Parse() with isFinal != 0
causes the previously-parsed buffer to be parsed,
at least partially, again. For example, say that I'm
sending it chunks of 1024 bytes at a time, and the
last root tag of my XML file is <test>. Let's say
that the last buffer chunk I sent it was as follows:
--
<nodeN>value</nodeN>
<data/>
</test>
--
The next time I call XML_ParseBuffer() or XML_Parse
(), I get the full complement of startElement,
endElement, and characterData events for
<nodeN>. This occurs after I've received the
<test> endElement event. Moreover, the error
occurs whether I send len = 0 to XML_Parse*() or if I
actually send data to it.
Is this a known bug? Is it fixed in a newer version?
I couldn't find any references to it on the bug list,
open or closed; nor in the CVS log for xmlparser.c.

In that case please post a small example that can
produce the behaviour you have reported.

Same thing occurs with the current CVS. This even
occurs when I actually send XML_Parse*() some text to
process. And to make things worse, XML_Parse()
returns false since it's trying to parse text past the close
tag of my root element, but the error code is set to 0.

Please retest with 1.95.3 or the current CVS.
Also, we are planning to release 1.95.4 today,
so if this is a bug, let's find out ASAP.
