| |
- Autotools-based build system for the UNIX/Linux/Mac OS X platforms
- Project files for VC++ 9
- Support for the ICU transcoder in VC++ 7.1, 8, and 9 project files
- libcurl-based net accessor
- Support for XInclude in DOM
- Support for both XPath 1 and XPath 2 models in the DOM XPath interface
- Support for the XML Schema subset of XPath 1 in DOM
- Conformance to the final DOM Level 3 interface specification
- Ability to provide custom DOM memory manager as well as tune the global DOM heap parameters
- All public and widely used interfaces as well as a large
portion of the implementation were converted to be 64-bit safe.
- Various XML Schema fixes including the fix for the large
maxOccurs and minOccurs bug as well as for the changed ##other
interpretation
- Reviewed and cleaned up diagnostics messages
- Optimizations for SAX/SAX2 and DOM parsing as well as XML Schema

Xerces-C++ 3.0.0 is a major release and includes
a number of application-breaking interface changes compared to
Xerces-C++ 2 series.
The following sub-sections provide an overview of the public API
changes between Xerces-C++ 2 series and this release.
| |
- XMLGrammarPoolImpl implementation has been moved to
framework/ and is now publicly accessible
- DOM XPath interfaces now support XPath 2 model
- A number of DOM interfaces (DOMLSInput, DOMLSOuput,
DOMLSParser, DOMLSSerializer, DOMConfiguration, etc.)
were added as part of the the final DOM Level 3
specification conformance work
|
| |
A large number of public APIs have been modified. Consult
individual interface documentation for details. The following
list gives an overview of major changes:
- Several DOM interfaces have been adjusted to conform to the final
DOM Level 3 specification
- DOM XPath interfaces have been adjusted to support both XPath 1
and XPath 2
- Many public interfaces that used int/long types to represent
memory-related sizes, counts, indexes, etc., have been modified
to use the 64-bit safe XMLSize_t type instead
