C++ Language Binding for DOM Level 2

[Back to Readme] [Go to C++ Language Binding for DOM Level 3]
This document contains the complete Apache Recommended C++ Language binding for the Document Object Model Level 2.0 Core, and for the Document Object Model Level 2.0 Traversal and Range.  Both are W3C Recommendation of November 13, 2000.

The definitions are divided into Core, Traversal, and Range. The headers are also available in Xerces-C++ distribution.

Note:

  1. Constructor and Destructors are implementation specific
  2. String is represented by "XMLCh*" which is a pointer to unsigned 16 bit type holding utf-16 values, null terminated.
  3. XMLSize_t is an implementation-dependent unsigned integral type
  4. C++ Memory Management:
    1. A member method "release()" is added for releasing any "orphaned" resources that were created through createXXXX factory method.
    2. Memory for any returned object e.g.
      • DOMNodeList* getChildNodes()
      • DOMNodeList* getElementsByTagName()
      • NamedNodeMap* getEntities()
      • ... etc.
      • are owned by implementation
