This a small file, so it should take more that a few minutes. Hmmm? Here is my code: url = 'http://download.publicradio.org/podcast/minnesota/news/programs/ 2009/09/10/grammar_20090910_64.mp3' file = 'C:\\Documents and Settings\\Compaq_Owner\\Desktop\ \GramGrate.mp3' import urllib.request b4 = urllib.request.urlretrieve(url, file) at this point, the cursor just sits and blinks forever. Any ideas? I really appreciate this guys. -- http://mail.python.org/mailman/listinfo/python-list

Essentially, what I am trying to learn by just reading articles on the web is how to access info on the web using Python, i.e. weather data, podcasts, etc... I have never done it before in any language. So, I am trying to do something that I've never done before with a language I barely know. Can be very frustrating. :( Thanks for all the help! -- http://mail.python.org/mailman/listinfo/python-list

I will play around with this. I am using Python 3.1, but I can't figure out why I can't use xml.dom.minidom.

How can I get this xml file and use the toprettyxml() method. Or something, so I can parse it. I don't have any books and the documentation for Python kind of sucks. I am a complete noob to Python and internet programming. (I'm sure that is obvious :) ) Thanks! Charlie Wrong? You didn't specify your OS environment, you didn't show the error message (and traceback), you posted an apparently unrelated question in the same thread (there's no XML inside a mp3 file). xml.dom.minidom.parse() takes a filename or a 'file' object as its first argument. You gave it a URL, so it complained. You can fix that either by using urllib.urlopen() or by separately copying the data to a local file and using its filename here. In general, I'd recommend against testing new code live against the internet, since errors can occur from the vagaries of the internet as well as from bugs in your code. Sometimes it's hard to tell the difference when the symptoms change each time you run. So I'd download the xml data that you want to test with to a local file, and test out your parsing logic against that copy. In fact, first testing will probably be against a simplified version of that copy. How do you download the file? Well, if you're using Firefox, you can browse to that page, and do View->Source. Then copy/paste that text into a text editor, and save it locally. Something similar probably works in other browsers, maybe even IE. Or you can use urlretrieve, as suggested earlier in this thread. But I'd make that a separate script, so that you can separate the bugs in downloading from the bugs in parsing. After everything mostly works, you can think about combining them.

Re: Podcast catcher in Python
C shouldn't be very hard. You just get the url of the file you want to connect to, then just use the normal connect sequence and read the file and print it out to the UNIX shell, then at the unix shell, just pipe it to an MP3. Or you could just do it with FILE *.

No, he's referring to the `xml.etree.elementtree` standard module: http://docs.python.org/library/xml.etree.elementtree.html#module-xml.etree.ElementTree Although since you're dealing with feeds, you might be able to use Universal Feed Parser, which is specifically for RSS/Atom: http://www.feedparser.org/ Cheers, Chris -- http://blog.rebertia.com -- http://mail.python.org/mailman/listinfo/python-list

Something like eTree will help immensely in this part. You'll also have to keep track of what you've already downloaded. I'd recommend taking a look at the RSS XML yourself, so you know what it is you have to parse out, and where to find it. From there, it should be fairly easy to come up with the proper query to pull it automatically out of the XML. As a kindness to the provider, I would recommend a fairly lengthy sleep between GETs, particularly if you want to scrape their back catalog. Unfortunately, I no longer have the script I created to do just such a thing in the past, but the process is rather straightforward, once you know where to look. ~G -- http://mail.python.org/mailman/listinfo/python-list
Re: Podcast catcher in Python
Also, if anyone could recommend some books that cover this type of programming, I would greatly appreciate it. Thanks! -- http://mail.python.org/mailman/listinfo/python-list
Podcast catcher in Python
Hi all, I would like to code a simple podcast catcher in Python merely as an exercise in internet programming. I am a CS student and new to Python, but understand Java fairly well. I understand how to connect to a server with urlopen, but then I don't understand how to download the mp3, or whatever, podcast? Do I need to somehow parse the XML document? I really don't know. Any ideas? Thanks! Chuck -- http://mail.python.org/mailman/listinfo/python-list
