BeautifulSoup提取div中的数据 [英] BeautifulSoup extract data within a div

问题描述

我已经浏览了一个小时的先前问题，并尝试了各种解决方案，但我无法解决这个问题.我已经从一个网站中提取了想要的结果，现在我只需要挖掘这些div以获取想要的特定信息即可.

I've browsed the previous questions for an hour and tried various solutions but I can't get this to work. I've extracted the results I want from a website, now I just have to mine these divs for the specific information I want.

结果是这样隔离的:

items=soup.findAll(id=re.compile("itembase"))

对于每个项目，我想从这段html中提取例如经纬度:

For each item, I want to extract for example the lat and long from this piece of html:

<div id="itembase29" class="result-item -result unselected clearfix even" data-
part="fl_base" data-lat="51.9006" data-lon="-8.51008" data-number="29" 
is-local="true" data-customer="32060963" data-addrid="1" 
data-id="4b00fae498e3cc370133e8a14fd75160">
<div class="arrow">
</div>

我该怎么做?谢谢.

推荐答案

1. 将您的html对象传递到漂亮的汤中.

1. Pass your html object into beautiful soup.

soup = BeautifulSoup(html)

查找div.

Find the div.

div = soup.div

从div获取您要查找的属性.

Get the attributes you're looking for from the div.

lat, lon = div.attrs['data-lat'], div.attrs['data-lon']

打印.

Print.

>>> print lat, lon
51.9006 -8.51008

为了清楚起见，我在其中保留了.attrs方法，但是更笼统地说，您可以像字典一样访问 any 元素的属性，甚至不需要方法，如下所示:div['data-lon'].这显然不适用于div的列表，您需要遍历该列表.

I left the .attrs method in there for clarity, but in more general terms, you can access the attributes of any element like a dictionary, you don't even really need the .attrs method, like so: div['data-lon']. This obviously doesnt work over a list of divs, you need to iterate over the list.

for div in divs:
    print div['data-lon'], div['data-lat']

或列表理解.

[(div['data-lon'], div['data-lat']) for div in divs]
