<documentation title="Closure XML">
<h1>Closure XML Parser</h1>
<p>An XML parser written in Common Lisp.</p>
<p>
Closure XML was written
by <a href="http://www.stud.uni-karlsruhe.de/~unk6/">Gilbert
Baumann</a> as part of the Closure web browser and is now
maintained by
<a href="mailto:david@lichteblau.com">David Lichteblau</a>.
It is licensed under Lisp-LGPL.
</p>
<p>
CXML implements a <a
href="http://www.w3.org/TR/REC-xml-names/">namespace-aware</a>,
validating <a
href="http://www.w3.org/TR/2000/REC-xml-20001006">XML 1.0</a>
parser as well as the <a
href="http://www.w3.org/TR/DOM-Level-2-Core/">DOM Level 2 Core</a>
interfaces. Two parser interfaces are offered, one SAX-like, the
other similar to StAX.

<ul class="nomargin">
<li>
Support for user-specified output encodings
using <a href="http://common-lisp.net/project/babel/">Babel</a>.
</li>
<li>
More support for input encodings, thanks to Pierre Mai.
</li>
<li>
Lisps using full 21 bit code points as characters are now fully
supported (including SBCL and Clozure CL) addition to the
existing support for 16 bit characters using UTF-16 (including
Allegro and LispWorks). The feature <tt>rune-is-utf-16</tt> is
now set on 16 bit Lisps. Make sure to update and
recompile both cxml and closure-common when upgrading.
</li>
<li>
New sink slot sink-omit-xml-declaration-p; functions cxml:unescaped
and sax:unescaped.
</li>
<li>
Added XPath support to the XMLS compatibility model.
</li>
<li>
Fixed various DTD serialization bugs. Fixed xmls compatibility
bugs. Fixed variable names in with-source. Fixed klacks-error
export. Consistently use strings as base URIs. Fixed PARSE for
non-file-streams. Added support for the UTF-8 "BOM", thanks to
Ivan Shvedunov.

Runes have been moved into a <b>separate project</b>,

as <b>separate tarballs</b> in the download directory. Please

<p class="nomargin"><tt>rel-2007-10-21</tt></p>
<ul class="nomargin">
<li>
Moved runes into a separate project.
</li>
<li>
Incompatible SAX changes: Added new classes
sax:abstract-handler, sax:content-handler, sax:default-handler.
Implementations of SAX handlers should now subclass one of
these classes.
</li>
<li>
fixed make-source :buffering nil, thanks to Magnus Henoch for
the report
</li>
<li>
fixed time and space usage in cases where entity references
follow each other (thanks to Ivan Shvedunov for the report)
</li>
<li>
In the DOM builder, grow a buffer for string normalization
exponentially, fixing a long-standing speed issue.
</li>
</ul>
<p class="nomargin"><tt>rel-2007-08-05</tt></p>
<ul class="nomargin">
<li>Various DTD serialization fixes</li>
<li>UTF-8 fix, thanks to Francis Leboutte</li>
</ul>
<p class="nomargin"><tt>rel-2007-07-07</tt></p>
<ul class="nomargin">
<li>
Fixed build on non-Unicode lisps. Fixed parsing on
non-Unicode lisps. Fixed Unicode detection on OpenMCL.
</li>
<li>New function <tt>cxml:parse</tt>.</li>
<li>Serialization no longer defaults to canonical form.</li>
<li>Fixed octet array argument to make-source.</li>
<li>
XMLS compatibility is not <i>bug-for-bug</i>-compatible with
XMLS any more. There is now a mode using pairs of local name
and namespace URI, and a second mode using qualified names
only. The old behaviour using pairs of prefix and local names
was removed. (Thanks to Douglas Crosher.)
</li>
<li>
SCL support (thanks to Douglas Crosher). Includes support for
implementations where URIs are valid namestrings, and a mode
where normal streams are used instead of xstreams and ystreams
(albeit both SCL-specific at this point).
</li>
<li>new convenience serialization function cxml:doctype. Various
DTD serialization fixes.</li>

<p class="nomargin"><tt>rel-2007-05-26</tt></p>
<ul class="nomargin">
<li>cxml.asd has been split up into <tt>cxml.asd</tt> for the
XML parser and <tt>runes.asd</tt> for the runes package, in
preparation of a complete split of the two systems. Future CXML
releases will use separate tarballs for <tt>runes</tt>
and <tt>cxml</tt>.</li>
<li>xml:base support (SAX and Klacks only, not yet used in DOM).
See documentation <a href="sax.html#saxparser">here</a> and <a
href="klacks.html#locator">here</a>.</li>
<li>New class <tt>broadcast-handler</tt> as a generalization
of the older <tt>sax-proxy</tt>.</li>
<li>New class <tt>tapping-source</tt>, a klacks source that
relays events from an upstream klacks source unchanged, while also
emitting them as SAX events to a user-specified handler at the
same time.</li>
<li>Changed attributes to carry an lname even when occurring
without a namespace. Added new functions attribute*,
unparse-attribute, and macro with-element*, with-namespace* to
the SAX generation wrapper API.</li>
<li>Klacks improvements: Incompatibly changed
klacks:find-element and find-event to consider the current event
as a result. Added klacks-error, klacks:expect, klacks:skip,
klacks:expecting-element. Fixed serialize-event to generate
start-prefix-mapping and end-prefix-mapping events. New function
map-current-namespace-declarations.</li>
