如何使用python和beautifulsoup获取标题属性? [英] How to obtain title attribute using python and beautifulsoup?

问题描述

假设以下内容:

<td title="I want this title" role="gridcell"><a onclick="open" href="#">TEXT</a></td>

现在，我已经成功使用以下方法分别找到了表和单个行:

Now, I've successfully found respectively the table and individual rows using:

for rows in soup.find_all(['tr']):
    for cells in rows.find_all(['td']):

通过打印cells我可以看到我找到了正确的行，但是我真的不确定如何获取title属性并将其另存为字符串吗?我尝试使用temp = soup.find('td')['title']，但是这样做会出错，所以很明显我做错了.

By printing cells I can see I've found the correct rows, but I'm really not sure how to take the title attribute and save it as a string? I've attempted to use temp = soup.find('td')['title'], but I'm getting errors doing this, so evidently I'm doing something wrong.

任何建议将不胜感激！

推荐答案

要获取元素的属性，可以将元素视为字典(

To get an attribute of an element, you can treat an element as a dictionary (reference):

soup.find('tag_name')['attribute_name']

而且，在您的情况下:

for tr in soup.find_all('tr'):
    for td in tr.find_all('td'):
        print(td.get('title', 'No title attribute'))

请注意，我已使用.get()方法来避免在没有title属性的td元素上失败.

Note that I've used .get() method to avoid failing on td elements with no title attribute.
