This programmers manual describes Mini-XML version 2.0, a small XML parsing library that you can use to read and write XML and XML-like data files in your application without requiring large non-standard libraries. Mini-XML only requires an ANSI C compatible compiler (GCC works, as do most vendors' ANSI C compilers) and a "make" program.
Mini-XML provides the following functionality:
Mini-XML doesn't do validation or other types of processing on the data based upon schema files or other sources of definition information, nor does it support character entities other than those required by the XML specification.
The Mini-XML library is copyright 2003-2004 by Michael Sweet.

Mini-XML was initially developed for the Gimp-Print project to replace the rather large and unwieldy libxml2 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:
It's bad enough that we require libxml2, but rolling our own XML parser is a bit more than we can handle.
I then replied with:
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.
I took my own challenge and coded furiously for two days to produced the initial public release of Mini-XML, total lines of code: 696. Robert promptly integrated Mini-XML into Gimp-Print and removed libxml2.
Thanks to lots of feedback and support from various developers, Mini-XML has evolved since then to provide a more complete XML implementation and now stands at a whopping 2,713 lines of code, compared to 103,893 lines of code for libxml2 version 2.6.9. Aside from Gimp-Print, Mini-XML is used for the following projects/software applications:
Please email me (mxml @ easysw . com) if you would like your project added or removed from this list, or if you have any comments/quotes you would like me to publish about your experiences with Mini-XML.
