31 Using the XPath Processor for C++
An explanation is given of how to use the XPath processor for C++.
Note:
Use the unified C++ application programming interface (API) in xml.hpp
for Oracle XML Developer's Kit (XDK) applications. The older, nonunified C++ API in oraxml.hpp
is deprecated and supported only for backward compatibility. It will be removed in a future release.
XPath Interfaces
The XPath interfaces are described.
Processor
Interface—basic XPath processor interface to which any XPath processor must conform.
CompProcessor
Interface—extended XPath processor that adds an ability to use XPath expressions precompiled into an internal binary representation. In this release this interface represents Oracle virtual machine interface.
Compiler
Interface—XPath compiler into binary representation.
NodeSetRef
Interface—defines references to node sets when they are returned by the XPath expression evaluation.
XPathException
Interface—exceptions for XPath compilers and processors.
XPathObject
Interface—interface for XPath 1.0 objects.
