I'm using xml.sax with unicode
strings of XML as input, originally entered in from a web form. On my local machine (python 2.5, using the default xmlreader expat, running through app engine), it works fine. However, the exact same code and input
strings on production app engine servers fail with "not well-formed". For example, it happens with the code below:
from xml import sax
class MyHandler(sax.ContentHandler):
pass
handler = MyHandler()
# Both of these unicode
strings return 'not well-formed'
# on app engine, but work locally
xml.parseString(u"<a>b</a>",handler)
xml.parseString(u"<!DOCTYPE a[<!ELEMENT a (#PCDATA)> ]><a>b</a>",handler)
# Both of these work, but output unicode
xml.parseString("<a>b</a>",handler)
xml.parseString("<!DOCTYPE a[<!ELEMENT a (#PCDATA)> ]><a>b</a>",handler)
resulting in the error:
File "<string>", line 1, in <module>
File "/base/python_dist/lib/python2.5/xml/sax/__init__.py", line 49, in parseString
parser.parse(inpsrc)

SAXParseException: <unknown>:1:1: not well-formed (invalid token)
Any reason why app engine's parser, which also uses python2.5 and expat, would fail when inputting unicode?
