Ah, I didn't realise I had a problem with escaping. I'm hesitant to
hack the parser when it is working correctly, but if I'm not escaping
data correctly on output then that must be fixed. The class
ElementWriter defines the following replacements for characters.
xmlEncoding.put(new Character('<'), "<");
xmlEncoding.put(new Character('>'), ">");
xmlEncoding.put(new Character('"'), """);
xmlEncoding.put(new Character('\''), "'");
xmlEncoding.put(new Character('&'), "&");
xmlEncoding.put(new Character('\n'), "
xmlEncoding.put(new Character('\r'), "
xmlEncoding.put(new Character('\t'), "	");
Perhaps this list should be extended. That's a fairly straightforward
Does anybody know of a library suitable generating output xml in a
streamy fashion? Perhaps I shouldn't be rolling my own like this.
