python - 如何用 BeautifulSoup 解析这个 HTML 代码？

Question

我想用 BeautifulSoup 解析这个 HTML 代码。

事实上，对于每项工作，我想获取时间和持续时间。 例如，我想获得:

June 2012 – Present (3 years 2 months)

但我明白了:

July 2012

这是我的 html 代码:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

from bs4 import BeautifulSoup

html_doc = """
<div id="background-experience" class="background-experience edit-default ">
<h3>Experience</h3>
<div id="experience-312465350" class="editable-item section-item current-position">
<div id="experience-312465350-view">
<header>
<h5 class="experience-logo" aria-hidden="true">

</div>
<script>$(function(){if(LI.Dialog){LI.Dialog().submitEvent.subscribe(function(type,args){var positionID;if(args[1]=='removePositionDialog'&&WebTracking&&WebTracking.trackUserAction){if(args[2]&&args[2].positionID){positionID=args[2].positionID;}WebTracking.trackUserAction('nprofile-edit-position-remove-submit',{positionID:positionID});}});}});</script>
</div>
"""
soup = BeautifulSoup(html_doc,'html.parser')
print soup.time.string

但是当我试图一直获取时，我只得到了一个。 我该如何解决我的问题？

提前致谢。

您需要使用<span>获取您的数据。使用 <time> 的方法只会给你内部文本，但 </time> 之外的文本不会像您的错误一样被打印。

为此，我们只需使用 <span>和属性 experience-date-locale .

使用以下代码片段来解析您的数据:

from bs4 import BeautifulSoup

soup = BeautifulSoup(html_doc)
all_spans = soup.find_all('span', 'experience-date-locale')

parsed_content = []

for span in all_spans:
    parsed_content.append(span.text)
