<p> This page describes some of the changes which should be expected
|
|
|
|
|
in Expat 3. These are intended as notes made by the developers as
|
|
|
|
|
things get thought through; these can change at any time. This is
|
|
|
|
|
<em>not</em> a projected feature list for Expat 3; to learn about the
|
|
|
|
|
target features, please read the <cite><a href="roadmap.html">Expat
|
|
|
|
|
Development Roadmap</a></cite>. The changes described here are much
|
|
|
|
|
more focused on the details of Expat 3, and no attempt has been made
|
|
|
|
|
to balance the description of small changes with major new feature
|
|
|
|
|
development. </p>
|
|
|
|
|
|
|
|
|
|
<p> This list is not complete; we'll add to this as we think of things
|
|
|
|
|
and have time to write about them. </p>

|
|
|
<li> Support for XML 1.1 and the corresponding namespaces updates. </li>
|
|
|
|
|
|
2005-01-28 22:24:21 -05:00
|
|
|
<li> The signature of the <code>XML_ParserReset()</code> method will
|
|
|
|
|
grow an additional argument allowing specification of what should be
|
2005-01-28 22:26:56 -05:00
|
|
|
reset. See <a href=
|
|
|
|
|

|
|
|
|
|
>bug report 1109116: <em>Optimize implementation of
|
|
|
|
|
XML_ParserReset</em></a> for more information. </li>
|

|
|
|
|
2003-10-23 01:24:11 -04:00
|
|
|
<li> All structural event callback functions will return an
|
|
|
|
|
<code>XML_Status</code> value that the parser will check. This will
|
|
|
|
|
allow an application to stop or suspend processing without having to
|
2005-01-31 09:52:55 -05:00
|
|
|
call <code>XML_StopParser</code>, which will therefore become obsolete. </li>
|
|
|
|
|
|
|
|
|
|
<li> The memory management function signatures will gain an additional
|
|
|
|
|
userData-like parameter, so that memory usage can be associated
|
|
|
|
|
with a context, allowing usage of memory pools and tracking of memory
|
|
|
|
|
usage per parser. The latter could be used to prevent the so-called
|
|
|
|
|
"million laughs" DoS attack. </li>
|
|
|
|
|
|
|
|
|
|
<li> Change how qualified names are reported. Instead of passing one
|
|
|
|
|
string where the name parts are separated by a special character, we
|
|
|
|
|
are going to use <code>QName</code> structs with members for local name,
|
|
|
|
|
namespace URI and prefix. This will apply to element names and attribute
|
|
|
|
|
names passed to <code>XML_StartElementHandler</code> and
|
|
|
|
|
<code>XML_EndElementHandler</code>. </li>
|
|
|
|
|
|
|
|
|
|
<li> We will try to add a way of setting additional encodings
|
|
|
|
|
by name, using the existing framework built around
|
|
|
|
|
<code>XML_UnknownEncodingHandler</code>. </li>
|
|
|
|
|
|
|
|
|
|
<li> Create different link symbols for different XML_Char sizes.
|
|
|
|
|
This would make it possible for different shared libraries making up an
|
|
|
|
|
application on linux, to link against expat shared libraries that have
|
|
|
|
|
been compiled with different definitions for XML_Char.</li>
