<p>This programmers manual describes Mini-XML version 2.4, a small
|
2007-04-26 22:21:37 +00:00
|
|
|
XML parsing library that you can use to read and write XML data
|
|
|
|
|
files in your C and C++ applications.</p>
|
2004-05-02 16:04:40 +00:00
|
|
|
|
|
|
|
|
<p>Mini-XML was initially developed for the <a
|
2007-04-26 22:21:37 +00:00
|
|
|
href='http://gutenprint.sf.net/'>Gutenprint</a> project to replace
|
|
|
|
|
the rather large and unwieldy <tt>libxml2</tt> library with
|
|
|
|
|
something substantially smaller and easier-to-use. It all began one
|
|
|
|
|
morning in June of 2003 when Robert posted the following sentence to
|
|
|
|
|
the developer's list:</p>
|
2004-05-02 16:04:40 +00:00
|
|
|
|
2007-04-26 22:21:37 +00:00
|
|
|
<blockquote><em>It's bad enough that we require libxml2, but rolling
|
2004-05-02 16:04:40 +00:00
|
|
|
our own XML parser is a bit more than we can
|
2007-04-26 22:21:37 +00:00
|
|
|
handle.</em></blockquote>
|
2004-05-02 16:04:40 +00:00
|
|
|
|
|
|
|
|
<p>I then replied with:</p>
|
|
|
|
|
|
2007-04-26 22:21:37 +00:00
|
|
|
<blockquote><em>Given the limited scope of what you use in XML, it
|
|
|
|
|
should be trivial to code a mini-XML API in a few hundred lines of
|
|
|
|
|
code.</em></blockquote>
|
2004-05-02 16:04:40 +00:00
|
|
|
|
|
|
|
|
<p>I took my own challenge and coded furiously for two days to
|
|
|
|
|
produced the initial public release of Mini-XML, total lines of
|
2007-04-18 19:25:26 +00:00
|
|
|
code: 696. Robert promptly integrated Mini-XML into Gutenprint
|
2004-05-02 16:04:40 +00:00
|
|
|
and removed libxml2.</p>
|
|
|
|
|
|
|
|
|
|
<p>Thanks to lots of feedback and support from various
|
|
|
|
|
developers, Mini-XML has evolved since then to provide a more
|
2007-04-18 19:25:26 +00:00
|
|
|
complete XML implementation and now stands at a whopping 3,441
|
2004-05-21 12:34:26 +00:00
|
|
|
lines of code, compared to 103,893 lines of code for libxml2
|
2007-04-18 19:25:26 +00:00
|
|
|
version 2.6.9.</p>
|
|
|
|
|
|
|
|
|
|
<p>Aside from Gutenprint, Mini-XML is used for the
