I want to parse downloaded RSS with lxml, but I don't know how to handle with UnicodeDecodeError?
request = urllib2.Request('http://wiadomosci.onet.pl/kraj/rss.xml')
response = urllib2.urlopen(request)
response = response.read()
encd = chardet.detect(response)['encoding']
parser = etree.XMLParser(ns_clean=True,recover=True,encoding=encd)
tree = etree.parse(response, parser)
But I get an error:
tree = etree.parse(response, parser)

You should probably only be trying to define the character encoding as a last resort, since it's clear what the encoding is based on the XML prolog (if not by the HTTP headers.) Anyway, it's unnecessary to pass the encoding to etree.XMLParser unless you want to override the encoding; so get rid of the encoding parameter and it should work.
Edit: okay, the problem actually seems to be with lxml. The following works, for whatever reason:
parser = etree.XMLParser(ns_clean=True, recover=True)
etree.parse('http://wiadomosci.onet.pl/kraj/rss.xml', parser)
