Question

我已使用BS4抓取了以下html，但似乎无法搜索艺术家代码。我已将此代码块分配给名为容器的变量，然后尝试

print container.tr.td["artist"]

没有运气。有什么建议值得赞赏吗？

<tr class="item">
  <!-- <td class="image"><a href="https://www.stargreen.com/kool-as-the-gang-44415.html" title="KOOL AS THE GANG " class="product-image"><img src="https://www.stargreen.com/media/catalog/product/cache/1/small_image/135x/9df78eab33525d08d6e5fb8d27136e95/K/o/KoolAsTheGang.jpg" width="135" height="135" alt="KOOL AS THE GANG " /></a></td> -->
  <td class="date">Sat, 30 Dec 2017</td>
  <td class="artist">kool as the gang</td>
  <td class="venue">100 club</td>
  <td class="link">
  <p class="availability out-of-stock">
    <span>Off Sale</span></p>
  </td>
</tr>

Answer 1

你的语法错了，＆＃34;艺术家＆＃34;是＆＃34;类＆＃34;的价值。属性试试这个：

[WARNING]: Consider using yum module rather than running yum

输出：

from bs4 import BeautifulSoup

html = """
<tr class="item">
<!-- <td class="image"><a href="https://www.stargreen.com/kool-as-the-gang-44415.html" title="KOOL AS THE GANG " class="product-image"><img src="https://www.stargreen.com/media/catalog/product/cache/1/small_image/135x/9df78eab33525d08d6e5fb8d27136e95/K/o/KoolAsTheGang.jpg" width="135" height="135" alt="KOOL AS THE GANG " /></a></td> -->
<td class="date">Sat, 30 Dec 2017</td>
<td class="artist">
                        kool as the gang                     </td>
<td class="venue">100 club</td>
<td class="link">
<p class="availability out-of-stock">
<span>Off Sale</span></p>
</td>
</tr>
"""

soup = BeautifulSoup(html, 'html.parser')
td = soup.find('td',{'class': 'artist'})
print (td.text.strip())

Answer 2

另一种方式。

使用container方法查找class select为'艺术家'的text元素。由于可能有多个，但您知道只有一个，请选择列表中唯一的元素，并请求其>>> HTML = open('sven.htm').read() >>> import bs4 >>> container = bs4.BeautifulSoup(HTML, 'lxml') >>> container.select('.artist')[0].text '\n kool as the gang '属性。
