如何用beauthoulsoupbs4抓取html标签（我不想要文本）

Question

<div class="tioTrivia lightblue bottomRight show sticky" data-login-url="http://www.ntvspor.net/uyelik/giris?returnUrl=/haber/futbol/131009/uniteda-yeni-arjantinli?utm_source=ntvspor%26utm_medium=oyun%26utm_campaign=iste_oyun" data-article-url="/haber/futbol/131009/uniteda-yeni-arjantinli?utm_source=ntvspor&utm_medium=oyun&utm_campaign=iste_oyun&ref=isteoyun" data-profile-url="http://www.ntvspor.net/uyelik/profil" data-content-class="trivia-widget-position" data-start-place="bottom-right" data-show-points="true" data-article-id="Tivibu,Manşet,Futbol,Futbol,Spor Toto Süper Lig,Beşiktaş,Gençlerbirliği" style="transition: opacity 0.5s ease-in-out 0s, right 0.5s ease 0s; top: 832px;">

这个HTML是我的目标。我想爬这条线

^{pr2}$

我特别需要这条线

"Tivibu,Manşet,Futbol,Futbol,Spor Toto Süper Lig,Beşiktaş,Gençlerbirliği"

我编写了这个函数，但没有返回任何函数

 def read_tags(self, news_url):
        try:

            self.checkRequests(news_url)
            tag = self.soup.find("div", {'class':'tioTrivia lightblue bottomRight show sticky'})
            if tag:
                tag = tag.get_text().encode(encoding='utf-8')
                return tag.lower()
            return
        except Exception, e:
            self.insertErrorLog('ntvspor.read_title', news_url, e)

Answer 1

简单到：

for t in soup.select('.tioTrivia'):
    print t.get('data-article-id')
