USAGE
# put this file (drv_libxml2.py) in PYTHONPATH
import xml.sax
reader = xml.sax.make_parser(["drv_libxml2"])
# ...and the rest is standard python sax.
CAVEATS
- Lexical handlers are supported, except for start/endEntity
(waiting for XmlReader.ResolveEntity) and start/endDTD
- Error callbacks are not exactly synchronous, they tend
to be invoked before the corresponding content callback,
because the underlying reader interface parses
data by chunks of 512 bytes
TODO
- search for TODO
- some ErrorHandler events (warning)
- some ContentHandler events (setDocumentLocator, skippedEntity)
- EntityResolver (using libxml2.?)
- DTDHandler (if/when libxml2 exposes such node types)
- DeclHandler (if/when libxml2 exposes such node types)
- property_xml_string?
- feature_string_interning?
- Incremental parser
- additional performance tuning:
- one might cache callbacks to avoid some name lookups
- one might implement a smarter way to pass attributes to startElement
(some kind of lazy evaluation?)
- there might be room for improvement in start/endPrefixMapping
- other?
