Thanks for these remarks. They confirm what I suspected, but was unsure of,
namely that it seems strange to be passing something other than a byte
stream to parser.parse.

Thanks for taking this seriously.

P.S. I love the new unicode plans. They are going to cause some pain at
first for everyone (Python team and developers), but in the long run they
are going to be a big plus for Python.

Python 3.0 distincts more clearly between unicode strings (called
"str"<br>
in 3.0) and bytes strings (called "bytes" in 3.0). The most
important<br>
point being that there is no more any implicit conversion between the<br>
two: you must explicitly use .encode() or .decode().<br>
<br>
Files opened in binary ("rb") mode returns byte strings, but files<br>
opened in text ("r") mode return unicode strings, which means you
can't<br>
give a text file to 3.0 library expecting a binary file, or vice-versa.<br>
<br>
What is more worrying is that XML, until decoded, should be considered a<br>
byte stream, so sax.parser should accept binary files rather than text<br>
files. I took a look at test_sax and indeed it considers XML as text<br>
rather than bytes :-(</blockquote><div><br>Thanks for these remarks. They
