| Cumulative history of software changes |
| The following sections list the changes in each release since Xalan-C++ version 0.40.0.
| Changes for Xalan-C++ version 1.9 |
| Major updates since version 1.8 include: Pluggable Memory Management. This feature allows applications to maintain precise control over memory allocations. This will allow users, with knowledge of their application's characteristics, to provide a more efficient allocation method than the general purpose procedures provided by the system. for more information on how to use this feature, please see the Pluggable Memory Management section of the Programming page. Improved stability on the execution of large stylesheets and XML documents. Because the current implementation relies on function recursion, certain stylesheets/input documents may cause the program stack to overflow and cause the application to fail. It also may inhibit executing stylesheets that are heavily dependent on recursive functions. This feature will prevent these types of failure. Provided a global option to pool all text node strings. This feature allows developers to set a flag to determine if a parsed source tree will pool the values of all of the text nodes in the XML document. By doing so, this can result in a significant reduction in memory usage, particularly if there are a lot of repeated values in text nodes. Please see the class descriptions for XalanSourceTreeDocument, XalanDefaultParsedSource, and XalanTransformer in the API Reference section for more information. Added support for Microsoft Studio .NET V7.1. Project files for Microsoft Studio .NET V7.1 have been provided under the directory xml-xalan\c\Projects\Win32\VC7.1. Upgrade from Xerces-C 2.5 to Xerces-C 2.6.
| Changes for Xalan-C++ version 1.8 |
| Major updates since version 1.7 include: Upgrade from Xerces-C 2.4 to Xerces-C 2.5. Provide build support for Cygwin and HP-UX 11.00 on Itanium. Although binary distributions are not provided for the Cygwin environment and HP-UX 11.00 on Itanium platform, the build configuration files provided in the source distribution can be used to build on these platforms. Project files for supporting Microsoft Visual Studio .NET. Although a binary distribution for the Microsoft Visual Studio .NET is not provided in this release, Visual Studio solution files are provided in the Windows source distribution for those who choose to build on this platform. Please see "Step for doing a Windows Build with Visual Studio .NET" for details. Additional changes to Xerces Deprecated DOM support. This is another step towards phasing out the support for Xerces Deprecated DOM. Users are encouraged to modify their applications to interface with the new Xerces DOM support. For more information on the effects of these changes to your build environment, please see "Steps for doing a Build with Xerces Deprecated DOM Support" Implemented optimizations to significantly improve the throughput of the ICU-enabled "format-number" function. Changes in the XML Serializer. The serializer will no longer put a newline after the xml header tag unless indent="yes". See bugzilla 24304 and 28386.
| Changes for Xalan-C++ version 1.7 |
| Major updates since version 1.6 include: Message Localization Support. This feature enables Xalan-C++ to issue diagnostic messages in languages other than the default language (English). In order to utilize this feature, the user must provide a version of the Xalan-C++ message catalog that has been translated in their language of choice. For more information on how to exploit this feature, please see Steps for doing a Build with Message Localization Support. Build, packaging, and installation improvements. Changes to the Xalan-C++ makefiles now allow for a more flexible build, packaging, and install process. Each step in a typical build process can be invoked by specifying the appropriate target, for example to build the executable, and/or samples, or install the build at user-specified location. For more information on building Xalan-C++, please see Steps for doing a Unix build . Deprecated DOM Support. The XercesBridge classes have been marked deprecated and moved into an exclusive directory within the xalanc/XercesParserLiaison directory called 'Deprecated'. If your application is dependent on these classes to interface with the deprecated Xerces DOM you must alter your include directive with the 'Deprecated' directory. For example: `#include "xalanc/XercesParserLiaison/XercesDocumentBridge.hpp"` should be changed to: `#include "xalanc/XercesParserLiaison/Deprecated/XercesDocumentBridge.hpp"` Upgrade from Xerces-C 2.3 to Xerces-C 2.4. Porting of ThreadSafe example to UNIX platform. Implementation of EXSLT string extension functions encode-uri() and decode-uri(). Implementation of EXSLT dynamic extension function evaluate(). Implementation of EXSLT date-time extension function date-time().
| Changes for Xalan-C++ version 1.6 |
| Major updates since version 1.5 include: Directory "sane include" reorganization. A new sub-directory called 'xalanc' has been added to the src directory (for source distribution packages) and include directory (for binary distribution packages). New source files which include Xalan headers will need to be modified to include the 'xalanc' prefix in the header path. For example: `#include <XPath/XObject.hpp>` will need to be changed to `#include <xalanc/XPath/XObject.hpp>` For Windows users, all project files have been modified to reflect this change. For UNIX users, please see Steps for doing a UNIX build for migration considerations.
| Changes for Xalan-C++ version 1.5 |
| Major updates since version 1.4 include: For Windows, Xalan-C++ is now packaged as a single DLL. The project files to build separate DLLs are now deprecated and will not be maintained. Support for Xerces-C++ DOMNode classes. New sample TransformToXercesDOM that illustrates how to perform a transform resulting in a Xerces-C++ DOMDocument Usage of the Xerces-C++ C++ namespace and creation of Xalan-C++ namespace.
| Changes for Xalan-C++ version 1.4 |
| Major updates since version 1.3 include: The Xalan-C++ distributions no longer include the Xerces-C++ headers and libraries. Accordingly, you must download the appropriate Xerces-C++ distribution (see Downloading what you need. 64-bit build for HP-11; untested 64-bit support for Solaris and AIX. New Linux platform and compiler: Redhat 7.2 with gcc 3.1. STLport is no longer required on any of our supported platforms. Alpha support for a number of EXSLT functions. ParsedSourceWrappers, a sample that illustrates how to perform transformations with input in the form of a pre-built XalanDOM or XalanSourceTree.
| Changes for Xalan-C++ version 1.3 |
| Major updates since version 1.2 include: A new and simplified command-line utility: the Xalan executable New XPath samples exploiting the XPathEvaluator C API and illustrating serialization of an XPath result set: SimpleXPathCAPI and SerializeNodeSet A new wrapper class that lets you pass in a Xerces DOM as input for a transformation Bug fixes. Changed XPathException to XalanXPathException because of a clash with a new Xerces class of the same name.
| Changes for Xalan-C++ version 1.2 |
| Major updates since version 1.1 include: Introduction of a library of extension functions Support for pre-parsed source documents and pre-compiled stylesheets in XalanTransformer and the C API. Support for stylesheet params in XalanTransformer and the C API Support for extension functions in XalanTransformer Performance enhancements
| Changes for Xalan-C++ version 1.1 |
| In addition to adding to the list of platforms on which Xalan-C++ builds, our focus for this release has been on bug fixes, performance enhancements, and providing a simplified C++ and C API for performing standard transformations. Major updates since version 1.0 include: Added HP-UX 11 build. Added Solaris build. Greatly improved performance. Improved conformance to the XSLT specification. Simplified the C++ API and provided a C API for performing standard transformations with the XalanTransformer class and associated header files. Added sample illustrating use of XalanTransformer and the new C++ API: XalanTransform. Added sample illustrating use of XalanTransformer, the new C API, and how to run Xalan-C++ and perform transformations on an Apache Web server: ApacheModuleXSLT. Added the StreamTransform sample. Eliminated dependencies on non-public Xerces headers; accordingly can now build with the Xerces distribution. Fixed namespace mapping and inheritance problems. Fixed failure of <copy-of ...> to include CRLFs (if any) in the result. Fixed bug sorting in reverse document order based on position. Fixed <xsl:number> bug with use of letter-value="traditional" for "classical" Greek numbering. Fixed use of <xsl:fallback> within a top-level extension function. Fixed HTML output method bug. The <HEAD> element was not including a <META> tag with the encoding. Fixed bug using key() in match patterns to find descendants. Fixed bug using the id() function in complex match patterns. Fixed problem outputting multiple single-character CDATA sections. Fixed problem outputting whitespace characters. Fixed problem transforming from a stream on UNIX platforms. Fixed a bug with the document() function, which was generating a syntax error if called in the following manner: document(string,/). Fixed named templates bug accepting global parameter when called with a parameter of the same name that the named template does not recognize.
