Hello to all! I want to parse a log file with the following format for example: TIMESTAMPEOperation FileName Bytes 12/Jan/2010:16:04:59 +0200 EXISTS sample3.3gp 37151 12/Jan/2010:16:04:59 +0200 EXISTSsample3.3gp 37151 12/Jan/2010:16:04:59 +0200 EXISTSsample3.3gp 37151 12/Jan/2010:16:04:59 +0200 EXISTSsample3.3gp 37151 12/Jan/2010:16:04:59 +0200 EXISTSsample3.3gp 37151 12/Jan/2010:16:05:05 +0200 DELETE sample3.3gp 37151 How can i count the operations for a month(e.g total of 40 Operations, 30 exists, 10 delete?) Any tips? Thanks in advance Antonis -- http://mail.python.org/mailman/listinfo/python-list

Text file to XML representation
Hello, I would like to make a program that takes a text file with the following representation: outlook = sunny | humidity <= 70: yes (2.0) | humidity > 70: no (3.0) outlook = overcast: yes (4.0) outlook = rainy | windy = TRUE: no (2.0) | windy = FALSE: yes (3.0) and convert it to xml file for example: Is there a way to do it?

Comparing file last access date
Hi to all, what i want is to search a folder, and if the last access date of the files in that folder is greater than, lets say 7 days, those files deleted. (Somekind of a file cleaner script) I had problems with converting now = today = datetime.date.today() and stats = os.stat(file) lastAccessDate = time.localtime(stats[7]) into matching formats so that if (now - lastAccessDate) > 7: delete the file what i do wrong Thanks in advance Antonis -- http://mail.python.org/mailman/listinfo/python-list

Apparently the server i'm trying to connect accepts only POST
connections. So xmlrpclib is useless.
I think I need the httplib library module.
Any hints?

Ok i found it. I sent the xml by hand with httplib module.
i use the last example of http://docs.python.org/library/httplib.html
and it worked.

cmd app and xml
Hi there,
i'm writing a console app using the cmd library. I also use
xml.dom.minidom to parse an xml file that i get as a response to an
HTTP Post request.
with
data = response.read()
i get the xml response from the server.
i then feed the parser with that data.
myDoc = parse(data)
but it doesn't work.
To make it work i open an xml file and the save the data to that file.
myDoc = parse('test.xml')
that worked.
But i don't want to use the local xml file?
What am i doing wrong?
Thanks in advance

Thank you all so much!!!
And it's not for a homework.
Just trying to find out the style DOM, SAX, ElementTree etc. that fits

asyncore loop and cmdloop problem
Hi to all,
i'm creating a command line application using asyncore and cmd. At
if __name__ == '__main__':
import socket
args = sys.argv[1:]
if not args:
print "Usage: %s querystring" % sys.argv[0]
sys.exit(0)
address = ('localhost', 0) # let the kernel give us a port
server = EchoServer(address)
ip, port = server.address # find out what port we were given
asyncore.loop()
CmdClass().cmdloop()
what i want is that the above commands asyncore.loop() and
CmdClass().cmdloop()
running at the same time. Meaning that while the application is in cmd
mode
with the cmdloop(), it is still able to listen for incoming messages?
What should i do?
thanks in advance

Is there a way that i can find that version of cmd?

Sockets and xml problem
Hi in the following code
class MyClientHandler(SocketServer.BaseRequestHandler):
def handle(self):
print self.client_address, now( )
time.sleep(5)
while True:
xmltxt = self.request.recv(1024)<--is this ok -
enough?
if not xmltxt: break
doc = minidom.parseString(data)
<--- it also fails for parse(data)
rootNode = doc.documentElement
level = 0
walk(rootNode, outFile, level)
<---just a function to print the xml
self.request.send('Echo=>%s at %s' % (data, now( )))
rootNode = doc.documentElement
level = 0
walk(rootNode, outFile, level)
self.request.send('Echo=>%s at %s' % (data, now( )))
self.request.close( )
# make a threaded server, listen/handle clients forever
myaddr = (myHost, myPort)
server = SocketServer.ThreadingTCPServer(myaddr, MyClientHandler)
server.serve_forever( )
I want to send XML messages from my client. The server sends back the
XML it receives but
the parser exits with error codes.
What am i doing wrong.
Thanks in advance

Threads with Cmd and socket server combination
hi, I have implement a command line app using Python's cmd library module and it works fine. I 've also create a simple threaded socket server. How can i merge the two ones, so that the console app, is also a listening server? How can i achieve that with threads? I'm trying for days and i can't make it work! I know it can be done with Twisted but i want to understand how thread works. The console: class BM(CmdBase): """Simple custom command processor""" def do_acmd(self): pass if __name__ == '__main__': BM().cmdloop() and the Server: class MyClientHandler(SocketServer.BaseRequestHandler): def handle(self): pass server = SocketServer.ThreadingTCPServer(myaddr, MyClientHandler) server.serve_forever( ) Thanks in advance Threads can be so difficult A.K. -- http://mail.python.org/mailman/listinfo/python-list

Well i did this:
SortedServers = []
for session in sessions:
for IP in session.getElementsByTagName("ipAddress"):
for iphn in session.getElementsByTagName("hostName"):
tempTuple = session.getAttribute("id"),
session.getAttribute("type"), iphn.childNodes[0].data,
IP.childNodes[0].data, session.getAttribute("status")
SortedServers.append(tempTuple)
Sorted = sorted(SortedServers, key=lambda id: SortedServers[0])
for item in Sorted:
print item
but the list is still unsorted and with u' in front of each item
(u'4', u'Server', u'aika74', u'ip', u'OFFLINE')
(u'29', u'Server', u'ando', u'ip2', u'OFFLINE')
How do i remove the u'

parsing different xml messages
Hello, I receive the following different Xml Messages from a socket: http://test.com/pt";> 5a62ded 101 Angie online Some IP http://test.com/pt";> Server server-1 is going down for redeploy! Which is the best way to make a distinction between them so that every time my app receives the one or the other, parse them correctly? Thanks Antonis K. -- http://mail.python.org/mailman/listinfo/python-list

I can't control the sending side. The app i'm writing just accepts incoming xml messages. Like the ones above. When i receive a message I parse it and print the information. I know how to parse both xml messages. What i want is to distinguish them so that i can trigger the appropriate parsing method. A.K. -- http://mail.python.org/mailman/listinfo/python-list
