This is the old XML parsing library provided in the GNOME framework. XML is a standard to build tag based structured documents. The internal document representation is as close as possible to the DOM interfaces. The interfaces of the XML library are by principle low level, there is nearly zero abstraction. Some features are: - C++ support - Updated code to follow more recent specs, added compatibility flag - Error handling, use a dedicated, overridable error handling function. - Support for CDATA. - Keep track of line numbers for better error reporting. - Support for PI (SAX one).
