BeautifulSoup 在 <img alt 标签中查找文本 [英] BeautifulSoup to find text within <img alt tag

问题描述

这是我从这行 Python 代码中得到的结果

Here is what I get back from this Python line of code

listm = soup.findAll('td',{'class':'thumb'})

当我遍历 listm 时，这是一个项目的示例...

when I iterate over the listm, here is an example of a item...

<a href="/property-search/property-details/1021206?StrtNum=1507"><img alt="1507 BOSTWICK LN" src="/res/slir/w75-h57-c4:3/propertyimages/20120904/BB/DSCN0738.JPG"/></a>

然而，我真正想要的是 <img alt=

However, what I really want is the "1507 BOSTWICK LN" within the <img alt=

我试过 .get_text 返回空白，我试过了lista = soup.findAll('td',{'class':'thumb'},{'alt':'img'})，以及其他一些无法获取文本的变体.

I have tried the .get_text with returns a blank, I've tried lista = soup.findAll('td',{'class':'thumb'},{'alt':'img'}), and several other variations that do not get me the text.

我想让 BeautifulSoup 返回文本，还是使用正则表达式?我对 RE 的了解非常丰富，任何输入都将不胜感激！！

I would like to have BeautifulSoup return the text, or would a regular expression work? My knowledge of of RE is zilch, any input would greatly be appreciated!!

推荐答案

试试这个:

listm = soup.findAll('td',{'class':'thumb'})
for elem in listm:
    print elem('img')[0]['alt']

这应该在每个 td 中找到 img 标签并打印 alt 属性的值.

This should find the img tag within each td and print the values of the alt attribute.

您不应该假设 img 标签的存在.改为这样做:

You should not assume the existence of the img tag. Do this instead:

listm = soup.findAll('td',{'class':'thumb'})
for elem in listm:
    imgs = elem('img')
    if imgs:
        print imgs['alt']
