IBM developerWorks: Making application programming easy with GNOME libraries, Part 3

Last month, George showed you how to build a genealogy
program with the GNOME libraries. This month he expands the
application by making it possible to load and save data using the
libxml library, a set of routines and structures for manipulating
an XML tree in memory.

“Having built a functioning genealogy application in last
month’s GNOMEnclature column, we still need to add a way to load
and save the application’s data. This is a two-part process: we
need to include file dialogs in the GUI, and use the libxml to read
and save the file. We will be extending the application developed
in the previous installment.”

“Let’s first concentrate on the actual loading and saving. For
this we will use libxml. Libxml is actually a set of routines and
structures for manipulating an XML tree in memory. You can load or
save this tree to file with one call (xmlParseFile and
xmlSaveFile). There are several ways we can use the library for our
purposes….”
