Hi everyone,
I have another question I'm hoping someone would be kind enough to answer. I
am new to parsing XML (not to mention much of Python itself) and I am trying
to parse an XML file. The file I am trying to parse is this one:
http://ws.audioscrobbler.com/2.0/user/bryansmith/topalbums.xml.
So far, I have written up a class for parsing this file in my attempts to
present to the user a list of top albums on their last.fm profile. If you
note, the artist name and album name are both signified by the <name> tag
which makes my job harder. If the tag names were different, I wouldn't have
a problem. Listed below is the class I have written to parse the file. My
question then is this: is there a way I can say something like "if tag_name
== album name tag then....elif tag_name == artist name tag....". I hope this
is clear.
As it stands right now, if I parse this file and print the results, this is
what I get (understandably) if I try to print out in the following fashion -
album (playcount): Vheissu (332), Thrice (289), The Artist in the Ambulance
(286), Thrice (210) and so on. Thrice is the artist name. I want to be able
to differentiate between the "artist" name tag and the "album" name tag.
Class as it stands right now:
class GetTopAlbums(ContentHandler):
in_album_tag = False
in_playcount_tag = False
def __init__(self, album, playcount):
ContentHandler.__init__(self)
self.album = album
self.playcount = playcount
self.data = []
def startElement(self, tag_name, attr):
if tag_name == "name":
self.in_album_tag = True
elif tag_name == "playcount":
self.in_playcount_tag = True
def endElement(self, tag_name):
if tag_name == "name":
content = "".join(self.data)
self.data = []
self.album.append(content)
self.in_album_tag = False
elif tag_name == "playcount":
content = "".join(self.data)
self.data = []
self.playcount.append(content)
self.in_playcount_tag = False
def characters(self, string):
if self.in_album_tag == True:
self.data.append(string)
elif self.in_playcount_tag == True:
self.data.append(string)
Thanks in advance!
Bryan
