As per https://peps.python.org/pep-0394/, the python binary can be one
of the following options:
- Python 2
- Python 3
- Not exist
All of the scripts in libxml2 use 'python', which may not exist.
As Python 2 reached EOL on the 1st January 2020, it's safe to move the
scripts to use python3 explicitly.
* parser.c: one more IsEmptyElement crazyness, that time in
external parsed entities if substitution is asked.
* python/tests/reader3.py: added a specific test.
Daniel
* xmlreader.c: seriously changed the way data are pushed to
the underlying parser, go by block of 512 bytes instead of
tryng to detect tag boundaries at that level. Changed the
way empty element are detected and tagged.
* python/tests/reader.py python/tests/reader2.py
python/tests/reader3.py: small changes mostly due to context
reporting being different and DTD node being reported. Some
errors previously undetected are now caught and fixed.
* doc/xmlreader.html: flagged last section as TODO
Daniel
* xmlreader.c python/tests/reader2.py: fixed another validity
checking in external parsed entities raised by Stéphane Bidoul
and added a specific regression test.
* python/tests/reader3.py: cleanup
Daniel
* xmlreader.c include/libxml/xmlreader.h doc/libxml2-api.xml:
extended the XmlTextReader API a bit, addding accessors for
the current doc and node, and an entity substitution mode for
the parser.
* python/libxml.py python/libxml2class.txt: related updates
* python/tests/Makefile.am python/tests/reader.py
python/tests/reader2.py python/tests/reader3.py: updated a bit
the old tests and added a new one to test the entities handling
