Eli Bendersky <eli...@gmail.com> added the comment: Both the Python ET and _elementtree use expat, but reach its parsing function in a different path when given a file-like object (StringIO, BytesIO).
Python ET reads the stream itself and passes the data to pyexpat's Parse method, which uses PyArg_ParseTuple to decode it. The latter turns a string into bytes when required, so the parsing of str streams is handled transparently. For _elementtree, on the other hand, ET directly calls the internal XMLParser._parse, which uses its own (C) loop to read from the stream. When it sees that it hasn't read bytes (but a string) it stops and falls back on parsing an empty document. The fix will have to be in the latter loop, probably just converting the read string to bytes before moving on. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue14246> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
