Question

hi all I’m trying to extract the “META” description from a webpage using libxml for python. When it encounters UTF chars it seems to choke and display garbage chars. However when getting the data via a regex I get the unicode chars just fine. Am I doing something wrong with libxml?

thanks

''' test encoding issues with utf8 '''

from lxml.html import fromstring
from lxml.html.clean import Cleaner
import urllib2
import re

url = 'http://www.youtube.com/watch?v=LE-JN7_rxtE'
page = urllib2.urlopen(url).read()


xmldoc = fromstring(page)
desc = xmldoc.xpath('/html/head/meta[@name="description"]/@content')
meta_description = desc[0].strip()

print "**** LIBXML TEST ****\n" 
print meta_description


print "**** REGEX TEST ******"
reg = re.compile(r'<meta name="description" content="(.*)">')
for desc in reg.findall(page):
  print desc

OUTPUTS:

**** LIBXML TEST ****

Does this help?

xmldoc = fromstring(page.decode('utf-8'))
