使用BeautifulSoup提取數據

這可能是一個簡單的問題，但我無法弄清楚。我無法從網頁的這部分與BeautifulSoup提取電子郵件地址和網址：使用BeautifulSoup提取數據

我試圖讓[email protected]和http://www.aachener-airport-taxi.de離開那裏。 soup.find(class='email')顯然不起作用，因爲class使編譯器認爲我想在括號內聲明一個。雖然我可以使用 for link in soup.find_all('a'): print(link.get('href'))來獲取所有鏈接，但我想要這個特定的鏈接。這些鏈接總是不同的，所以我不能爲它們設置正則表達式，所以我想我們必須親手瀏覽html-body。

print(soup.find("span",{"class":"text"}).text) 
print(soup.find(attrs={"class":"website"}).a["href"]) 
[email protected] 
http://www.aachener-airport-taxi.de

不錯，謝謝。第一種方法實際上返回的是電話號碼，而不是電子郵件，因爲電話號碼嵌套在我發佈的HTML主體部分上方几行的類似結構中，但是我可以修改它以提取郵件：）我使用'mail = soup.find（attrs = {「class」：「email」}）。a [「href」]'，這會返回mailto：info @ taxi-ac.de'。你只需要string.split結果，你去了。可能不是教科書的方法，但嘿它的作品。 – 2014-12-06 03:03:13
