I am trying to parse with the etree.HTML () file the text encoded as UTF-8 without success.
→ python Python 2.7.1 (r271:86832, Jun 16 2011, 16:59:05) [GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> from lxml import etree >>> import requests >>> headers = {'User-Agent': "Opera/9.80 (Macintosh; Intel Mac OS X 10.8.0) Presto/2.12.363 Version/12.50"} >>> r = requests.get("http://www.rakuten.co.jp/", headers=headers) >>> r.status_code 200 >>> r.headers {'x-cache': 'MISS from www.rakuten.co.jp', 'transfer-encoding': 'chunked', 'set-cookie': 'wPzd=lng%3DNA%3Acnt%3DCA; expires=Tue, 13-Aug-2013 16:51:38 GMT; path=/; domain=www.rakuten.co.jp', 'server': 'Apache', 'pragma': 'no-cache', 'cache-control': 'private', 'date': 'Mon, 13 Aug 2012 16:51:38 GMT', 'content-type': 'text/html; charset=EUC-JP'} >>> responsetext = r.text
So far so good. The text of the answer is good, and this is a Unicode string. Now, if I try to get a list of CSS URIs. No problems.
>>> tree = etree.HTML(responsetext) >>> csspathlist = tree.xpath('//link[@rel="stylesheet"]/@href') >>> csspathlist ['http://a.ichiba.jp.rakuten-static.com/com/inc/home/20080930/opt/css/normal/common.css?v=1207111500', 'http://a.ichiba.jp.rakuten-static.com/com/inc/home/20080930/opt/css/normal/layout.css?v=1207111500', 'http://a.ichiba.jp.rakuten-static.com/com/inc/home/20080930/opt/css/normal/sidecolumn.css?v=1207111500', 'http://a.ichiba.jp.rakuten-static.com/com/inc/home/20080930/beta/css/liquid/api.css?v=1207111500', '/com/inc/home/20080930/beta/css/liquid/myrakuten_dpgs.css', 'http://a.ichiba.jp.rakuten-static.com/com/inc/home/20080930/opt/css/normal/leftcolumn.css?v=1207111500', 'http://a.ichiba.jp.rakuten-static.com/com/inc/home/20080930/opt/css/normal/header.css?v=1207111500', '/com/inc/home/20080930/opt/css/normal/footer.css', 'http://a.ichiba.jp.rakuten-static.com/com/inc/home/20080930/beta/css/liquid/ipad.css', 'http://a.ichiba.jp.rakuten-static.com/com/inc/home/20080930/opt/css/normal/genre.css?v=1207111500', 'http://a.ichiba.jp.rakuten-static.com/com/inc/home/20080930/opt/css/normal/supersale.css?v=1207111500', '/com/inc/home/20080930/beta/css/liquid/rakuten_membership.css', 'http://a.ichiba.jp.rakuten-static.com/com/inc/home/20080930/beta/css/noscript/set.css?v=1207111500', 'http://a.ichiba.jp.rakuten-static.com/com/inc/home/20080930/beta/css/liquid/suggest-2.0.1.css?v=1204231500', 'http://a.ichiba.jp.rakuten-static.com/com/inc/home/20080930/beta/css/liquid/liquid_banner.css?v=1203011138', 'http://a.ichiba.jp.rakuten-static.com/com/inc/home/20080930/beta/css/liquid/area_announce.css?v=1203011138']
Now, let's move from Unicode to UTF-8 and again request a list of CSS URIs.
>>> htmltext = responsetext.encode('utf-8') >>> tree2 = etree.HTML(htmltext) >>> csspathlist2 = tree2.xpath('//link[@rel="stylesheet"]/@href') >>> csspathlist2 []
I get an empty list.
>>> etree.tostring(tree2) '<html lang="ja" xmlns="http://www.w3.org/1999/xhtml" xmlns:og="http://ogp.me/ns#" xmlns:fb="http://www.facebook.com/2008/fbml"><head><meta http-equiv="Content-Type" content="text/html; charset=EUC-JP"/><meta http-equiv="Content-Style-Type" content="text/css"/><meta http-equiv="Content-Script-Type" content="text/javascript"/><title/></head></html>'
In fact, the second parsing stopped right after the first Japanese character in the title.
<meta http-equiv="Content-Script-Type" content="text/javascript"/> <title> 【楽天市場】Shopping is Entertainment! ： インターネット最大級の通信販売、通販オンラインショッピングコミュニティ </title>
I'm still trying to figure out what I did wrong.
