The following snippet does what you want:
>>>
from sgmllib import SGMLParser
class MyParser(SGMLParser):
def __init__(self):
SGMLParser.__init__(self)
self.tagcount = {}
self.links = set()
# Tag count handling
# ------------------
def handle_starttag(self,tag,method,args):
self.tagcount[tag] = self.tagcount.get(tag,0) + 1
method(args)
def unknown_starttag(self,tag,args):
self.tagcount[tag] = self.tagcount.get(tag,0) + 1
# Argument handling
# -----------------
def start_a(self,args):
self.links.update([value for name, value in args if name == "href"])
parser = MyParser()
parser.feed(file("test.html").read()) # Insert your data source here...
parser.close()
print parser.tagcount
print parser.links
>>>
See the documentation for sgmllib for more info on handle_starttag (whose
logic might just as well have been implemented in start_a, but if you want
argument handling for more tags, it's best to keep it at this one central
place) and unknown_starttag.
