Oracle XML Class Generator 18.104.22.168.0 Production (C++)
July 17, 2000
Updated to match internal changes in the XML parser, otherwise no changes.
Oracle XML Class Generator 22.214.171.124.0 Production (C++)
External DTD parsing: The Class Generator can now parse an
external DTD directly without requiring a complete (dummy) document.
This uses a new feature of the Oracle XML Parser version 2.0.1, the
xmlparsedtd API. The provided command-line program xmlcg
has a new '-d' option to use it, see below.
Oracle XML Class Generator 126.96.36.199.0 Production (C++)
The XML Class Generator takes a Document Type Definition (DTD) and
generates classes for each defined element. Those classes are then used
in a C++ program to construct XML documents conforming to the DTD.
Supported operating systems are Solaris 2.6, Linux 2.2, HPUX 11.0 and
NT 4 (Service Pack 3 and above).
Input is an XML document containing a DTD, or an external DTD. The document
body itself is ignored; only the DTD is relevant, though the document must
conform to the DTD. The underlying XML parser only accepts file names for the
document and associated external entities. In future releases, URIs for
additional protocols will be accepted.
The following input file encodings are supported: UTF-8, UTF-16,
US-ASCII, ISO-10646-UCS-2, ISO-8859-1, ISO-8859-2, ISO-8859-3, ISO-8859-4,
ISO-8859-5, ISO-8859-6, ISO-8859-7, ISO-8859-8, ISO-8859-9, EUC-JP, SHIFT_JIS,
BIG5, GB2312, KOI8-R, EBCDIC-CP-US, EBCDIC-CP-CA, EBCDIC-CP-NL, EBCDIC-CP-WT,
EBCDIC-CP-DK, EBCDIC-CP-NO, EBCDIC-CP-FI, EBCDIC-CP-SE, EBCDIC-CP-IT,
EBCDIC-CP-ES, EBCDIC-CP-GB, EBCDIC-CP-FR, EBCDIC-CP-HE, EBCDIC-CP-BE,
EBCDIC-CP-CH, EBCDIC-CP-ROECE, EBCDIC-CP-YU, and EBCDIC-CP-IS.
In addition, any character set specified in Appendix A, Character Sets,
of the Oracle National Language Support Guide may be used.
In order to be able to use these encodings, you must have the
ORACLE_HOME environment variable set and pointing to the location
of your Oracle installation. In addition, the environment variables
ORA_NLS, ORA_NLS32, and ORA_NLS33 must be set
to point to the location of the NLS data files. On Unix systems, this is
usually $ORACLE_HOME/ocommon/nls/admin/data. On Windows NT,
this is usually $ORACLE_HOME/nlsrtl/admin/nlsdata.
The default encoding is UTF-8. It is recommended that you set
the default encoding explicitly if using only single byte character sets
(such as US-ASCII or any of the ISO-8859 character sets) for performance
up to twice as fast as with multibyte character sets such as UTF-8.
Output is a pair of C++ source files, .cpp and .h, named after the DTD.
Constructors are provided for each class (element) that allow an object to
be created in two different ways: initially empty, then adding the children
or data after the initial creation, or created with the initial full set of
children or initial data. A method is provided for #PCDATA (and Mixed)
elements to set the data and, when appropriate, set an element's attributes.

Relevant XML Standards
The following files and directories are found in this release:
The following libraries are included:
|bin/||Standalone Class Generator "xmlcg"
|lib/||XML and support libraries
|mesg/||Error message files (including cause/action
information in the .msg). Currently English only.
|libxml8.a||XML Parser/XSL Processor
|libxmlg8.a||XML Class Generator
|libxmlc8.a||Compatibility library needed to
link with Oracle 8.1.5
|libnls8.a||National Language Support
The standalone parser may be called as an executable by invoking
xmlcg [flags] <XML document or External DTD>
where the optional flags are as follows:
|-d name||DTD - Input is an external
DTD with the given name
|-o directory||Output - Output directory
for generated files (default is current directory)
|-e encoding||Encoding - Default input
|-h||Help - show this usage help
|-v||Version - show the Class Generator version
Error Message Languages
An error message file is provided in the mesg/ subdirectory.
Currently, the only message file is in English although message files
for other languages may be supplied in future releases. You should set
the environment variable ORA_XML_MESG to point to the
absolute path of the mesg/ subdirectory. Alternately,
if you have an $ORACLE_HOME installed, you may copy the contents
of the mesg/ subdirectory to the $ORACLE_HOME/oracore/mesg
