need guidance on XML parsing

[matrixebiz]

Hello, looking for some help to modify this code/script;

1 import datetime 
2 
 
3 CHANNELS = {} 
4 
 
5 #################################################################################################### 
6 def initchannels(xmlguide): 
7 	channels = {} 
8 	for key in xmlguide: 
9 		channel = {} 
10 		channels[0] = channel 
11 
 
12 	CHANNELS = channels 
13 
 
14 
 
15 def format_time(timestamp): 
16 	return datetime.datetime.strptime(timestamp[:12], "%Y%m%d%H%M%S") 
17 
 
18 
 
19 #################################################################################################### 
20 def epgguide(channelID, currentTime): 
21 	epgInfo = 'No EPG Info Available' 
22 	#Log("currenttime ---------------- " + str(currentTime)) 
23 	try: 
24 		for channel in CHANNELS: 
25 			if channel.id in channelID: 
26 				for prog in channel: 
27 					if int(currentTime) > int(format_time(prog.key['start'])) and int(currentTime)+120 < int(format_time(prog.key['stop'])): 
28 						epgInfo = epgInfo + ' | ' + prog + '[ ' + format_time(key['start']) + ' - ' + format_time(key['stop']) + ' ]' 
29 	except: 
30 		pass 
31 	return epgInfo

I just need it to be able to read the attached guide.xml to parse the info.
Thank you

I would like it to;

a) Init function [def initchannels(xmlguide)] that parses the 'guide.xml' at the start when Refreshing Channel Listing is called
b) Get Channel content based on current time [def epgguide(channelID, currentTime)]

Thank you

That looks like python, I'd take a look at some of the python xml parsers. sax is probably a good start since you want to parse the whole XML on init.

Ok, I'll check with some Python programmers. Thx
