Accessing "sub elements" with xml.sax ?

Hi, I'm trying to use xml.sax (from xml.sax.handler import ContentHandler) to processes the following data: I've figured out how to access the attributes in "row" - but I want to also access the "analytics" child element. I've tried: class YahooHandler(ContentHandler): ccountNum) def

Python code for 2.5 and 2.4?

I was given code that was written for python 2.5, and uses simple functions like 'all' which are not present in 2.4 I want to make the code 2.4 compatible. What is the best way to do this? If I define function 'all', then won't I break 2.5 compatability? Thanks, Joseph -- http://mail.python.or

H! I'm searching for a simple bin2chr("01110011") function that can convert all my 8bit data to a chr so I can use something like this: def bin(i): l = ['', '0001', '0010', '0011', '0100', '0101', '0110', '0111', '1000', '1001', '1010', '1011', '1100', '1101', '1110', '']
