Hi i'm doing the following:

def start_element(name, attrs):
print 'Start element:', name, attrs
def end_element(name):
print 'End element:', name
def char_data(data):
print 'Character data:', repr(data)

class SimpleServer(LineReceiver): # Using Twisted

def connectionMade(self):
print 'Connection from: ', self.transport.client

def connectionLost(self, reason):
print self.transport.client, 'Disconnected'

def dataReceived(self, line):
"""Here the XML Parser"""

p = xml.parsers.expat.ParserCreate()

p.StartElementHandler = start_element
p.EndElementHandler = end_element
p.CharacterDataHandler = char_data
p.Parse(line, 1)

I got the following error
--- <exception caught here> ---
File "/usr/lib/python2.6/site-packages/Twisted-10.0.0-py2.6-linux-
x86_64.egg/twisted/internet/selectreactor.py", line 146, in

why = getattr(selectable, method)()
File "/usr/lib/python2.6/site-packages/Twisted-10.0.0-py2.6-linux-

File "stdiodemo.py", line 419, in dataReceived
p.Parse(line, 1)
xml.parsers.expat.ExpatError: syntax error: line 1, column 0

The XML Message is coming in the form of:

Please give me some hints

Does Expat get this line as well? If so, that's the reason why you get
an error at line 1, column 0.

Yes but how can i fix it, how to "ignore" the headers and parse only
the XML?
Thanks

The headers are followed by exactly one empty line, so you you simply
could remove lines up until including this empty line and then hand over
the data to the parser.

Consider reading the answers you got in the last thread that you opened
with exactly this question.
