feature from more recent versions anyway, and the former is compatible with more servers. Added debug traces. Fixes G718-020 git-svn-id: svn+ssh://svn.eu.adacore.com/Dev/trunk/xmlada@113673 936e1b1b-40f2-da11-902a-00137254ae57

New features in version 3.0 (Development version)
|
|
===========================
|
|
|
|
WARNING: the version number of XML/Ada was bumper to 3.x because the API
|
|
has changed slightly in several packages, providing reference-counted types
|
|
and thus automatic memory management. This was necessary to fix some meory
|
|
leaks that couldn't be fix as easily otherwise.
|
|
|
|
Input_Sources:
|
|
- G718-020 http input now uses http 1.0 instead of http 1.1, since the
|
|
latter is not always properly understood by servers, and we do not need
|
|
new features from newer versions anyway
|
|
|
|
Schema validation:
|
|
- G404-019 fixed handling of use='required' in schemas
|
|
- G425-003 schema-date_time.ads now contains subprograms to convert to
|
|
standard Ada time representation
|
|
- G510-017 API change: ref-counted grammar
|
|
The XML_Grammar type is now reference-counted, and memory management is
|
|
taken care of automatically. This is a change of API, since the Free
|
|
subprogram no longer exists and doesn't need to be called by the user in
|
|
any case.
|
|
|
|
SAX:
|
|
- API change: sax.locators is now ref-counted
|
|
The types in Sax.Locators are now reference-counted, and memory management
|
|
is taken care of automatically. This affects the primitive operation
|
|
Set_Document_Locator of the SAX parser.
|
|
Unfortunately, the memory leaks could not easily be resolved without
|
|
breaking the API here. The changes are minor, but might affect user code,
|
|
removing all needs for calling Ref/Unref
|
|
|
|
DOM:
|
|
- FA12-014, G508-017 DOM.Core.Write: new subprogram
|
|
It outputs a Node, based on Ada95 streams.
|
|
This provides additional capabilities over DOM.Core.Print, for instance
|
|
output to sockets or memory without going through a file on disk.
|
|
See also the new example dom/tests/tostring.adb
|
|
- G522-006 Support for pretty-printing in the output
|
|
When a DOM tree is output, an extra parameter was added to Write to
|
|
control the pretty-printing (ie special handling of whitespaces and
|
|
newline character to hopefully make the output more readable to humans)
|
|
|
|
New features in version 2.3
|
|
===========================
|
|
|
|
Schema validation:
|
|
- Add support for parsing several .xsd files before parsing an XML file.
|
|
This was possible before but might have resulted in errors about multiply
|
|
defined elements and types
|
|
- Attribute's value normalization is now done based on the value of their
|
|
whitespace facet.
|
|
|
|
New features in version 2.2
|
|
===========================
|
|
|
|
Unicode:
|
|
- Properties of characters are now stored in tables, instead of computed
|
|
through tests. This is more efficient
|
|
- Support for new encodings: "ascii" and "utf8"
|
|
|
|
SAX parser:
|
|
- We now pass the newer version of the XML Conformance Testsuite
|
|
- Better compatibility with valgrind: no error message is issued by valgrind.
|
|
There were false warnings, but might make it harder to use valgrind on
|
|
your own application.
|
|
|
|
DOM:
|
|
- DOM.Core.Documents.Get_Element_By_Id is now implemented
|
|
- Partial port to DOM 3.0
|
|
|
|
Schema validation:
|
|
- Added support for base64Binary type
|
|
|
|
New features in version 2.1
|
|
===========================
|
|
|
|
Unicode:
|
|
- E930-022 Added support for windows-1252 encoding
|
|
|
|
SAX parser:
|
|
- E912-011 No longer use an exception internally to report the end of stream
|
|
|
|
DOM:
|
|
- DOM.Core.Nodes.Print now uses the <../> syntax to represent empty nodes
|
|
- EB02-005 DOM.Core.Nodes.Print now prints the namespace declarations
|
|
|
|
Schema validation:
|
|
- E802-003 Added support for time-related types, like dateTime, time, date,..
|
|
- Added support for totalDigits and fractionDigits facets for integer types
|
|
- Added support for all missing simple types: anyURI, hexBinary, double, ...
|
|
- Improve support for arbitrary precision types like decimal and integer
|
|
- Add support for using an attributeGroup reference when defining a local
|
|
type for an element
|
|
|
|
Documentation:
|
|
- More code examples
|
|
- Describe the syntax to use for XML Schemas
|
|
|
|
New features in version 2.0
|
|

|
|
|
- Initial support for schema validation is now provided.
|
|
|
|
- Documentation is now provided in PDF format
|
|
|
|
- Enhanced documentation; examples of use are now provided
|
|
|
|
- D507-011: Dom.Core.Nodes.Print can now output real newline characters
|
|
|
|

|
|
or encoding scheme
|
|
|
|

a document
|
|
|
|
- D714-002: Comments are now properly stored in the DOM tree
|
|
|
|

|
|
|
|

|
|
|

on how to get the context of an entity expansion if you want even better
|
|
locations.
|
|
|
|
- CB14-002 Add support for SAX's Entity_Resolver

|
|

|
|
|
|
- Better integration with GtkAda: A special SAX reader is provided that can
|
