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? u Stéphane Bidoul <sbi@skynet.be>z0.3� N� �utf8� c C s | d kr |
