This chapter contains these topics:
Note:Use the new unified C++ API in
xml.hppfor new XDK applications. The old C++ API in
oraxml.hppis deprecated and supported only for backward compatibility, but will not be enhanced. It will be removed in a future release.
XSLT for C++ is provided with Oracle Database. Sample files are located at
readme.html in the root directory of the software archive contains release specific information including bug fixes and API additions.
See Also:"XVM Processor"
This is the namespace for XSLT compilers and transformers.
XslException Interface - Root interface for all XSLT-related exceptions.
Transformer Interface -Basic XSLT processor. This interface can be used to invoke all XSLT processors.
CompTransformer Interface - Extended XSLT processor. This interface can be used only with processors that create intermediate binary bytecode (currently XVM-based processor only).
Compiler Interface - XSLT compiler. It is used for compilers that compile XSLT into binary bytecode.

There are two inputs to
The XML document
The stylesheet to be applied to the XML document
Any XSLT processor is initiated by calling the tools factory to create a particular XSLT transformer or compiler.
The stylesheet is supplied to any transformer by calling
setXSL() member functions.
The XML instance document is supplied as a parameter to the transform member functions.
The resultant document (XML, HTML, VML, and so on) is typically sent to an application for further processing. The document is sent as a DOM tree or as a sequence of SAX events. SAX events are produced if a SAX event handler is provided by the user.
The application terminates the XSLT processors by invoking their destructors.
XSLT for C++ can be invoked in two ways:
By invoking the executable on the command line
By writing C++ code and using the supplied APIs
XSLT for C++ can be called as an executable by invoking
XSLT for C++ can also be invoked by writing code to use the supplied APIs. The code must be compiled using the headers in the
public subdirectory and linked against the libraries in the
lib subdirectory. Please see the
xdk/demo/cpp/new for full details of how to build your program.
$ORACLE_HOME/xdk/demo/cpp/parser/ directory contains several XML applications to illustrate how to use the XSLT for C++.
Table 26-1 lists the sample files.
