美汤缺失部分

Question

我正试着从红鳍上取回房子的销售价格。

以下是HTML的一部分：

<div class="timeline"><div class="property-history-content-container"><div class="timeline-content"><h4 class="section-header col-12">Today</h4><div class="sold-row row PropertyHistoryEventRow" id="propertyHistory-0"><div class="col-4"><p>Oct 15, 2020</p><p class="subtext">Date</p></div><div class="description-col col-4"><div>Sold (MLS) (Closed)</div><div></div><p class="subtext">ACTRIS #5085856</p></div><div class="col-4"><div class="price-col number">$302,000<span class="number empty"> </span></div><p class="subtext">Price</p></div></div><div class=" row PropertyHistoryEventRow" id="propertyHistory-1"><div class="col-4"><p>Sep 16, 2020</p><p class="subtext">Date</p></div><div class="description-col col-4"><div>Contingent (Active Under Contract)</div><div></div><p class="subtext">ACTRIS #5085856</p></div><div class="col-4"><div class="price-col number">—<span class="number empty"> </span></div><p class="subtext">Price</p></div></div><div class=" row PropertyHistoryEventRow" id="propertyHistory-2"><div class="col-4"><p>Sep 8, 2020</p><p class="subtext">Date</p></div><div class="description-col col-4"><div>Pending (Pending - Taking Backups)</div><div></div><p class="subtext">ACTRIS #5085856</p></div><div class="col-4"><div class="price-col number">—<span class="number empty"> </span></div><p class="subtext">Price</p></div></div><div class=" row PropertyHistoryEventRow" id="propertyHistory-3"><div class="col-4"><p>Sep 5, 2020</p><p class="subtext">Date</p></div><div class="description-col col-4"><div>Listed (Active)</div><div></div><p class="subtext">ACTRIS #5085856</p></div><div class="col-4"><div class="price-col number">$294,900<span class="number empty"> </span></div><p class="subtext">Price</p></div></div></div></div></div>

下面是邮政编码的一部分：

url = 'https://www.redfin.com/TX/Cedar-Park/615-Fence-Post-Pass-78613/home/32939011'
driver.get(url)
soup = BeautifulSoup(driver.page_source, 'html.parser') 
soup.find_all(class_ = 'timeline-content')

然而，代码不返回“出售”事件，只有3个事件之前出售。

下面是soup.find_all(class_ = 'timeline-content')的结果

[<div class="timeline-content"><h4 class="section-header col-12">Today</h4><div class="row PropertyHistoryEventRow" id="propertyHistory-0"><div class="col-4"><p>Sep 16, 2020</p><p class="subtext">Date</p></div><div class="description-col col-4"><div>Contingent (Active Under Contract)</div><div></div><p class="subtext">ACTRIS #5085856</p></div><div class="col-4"><div class="price-col number">—<span class="number empty"> </span></div><p class="subtext">Price</p></div></div><div class="row PropertyHistoryEventRow" id="propertyHistory-1"><div class="col-4"><p>Sep 8, 2020</p><p class="subtext">Date</p></div><div class="description-col col-4"><div>Pending (Pending - Taking Backups)</div><div></div><p class="subtext">ACTRIS #5085856</p></div><div class="col-4"><div class="price-col number">—<span class="number empty"> </span></div><p class="subtext">Price</p></div></div><div class="row PropertyHistoryEventRow" id="propertyHistory-2"><div class="col-4"><p>Sep 5, 2020</p><p class="subtext">Date</p></div><div class="description-col col-4"><div>Listed (Active)</div><div></div><p class="subtext">ACTRIS #5085856</p></div><div class="col-4"><div class="price-col number empty">**<span class="number empty"> </span></div><p class="subtext">Price</p></div></div></div>]

Answer 1

添加您想要找到的标签，也可以使用soup.find('div', class_='timeline-content')。

基于提供的html的示例

from bs4 import BeautifulSoup

html = """
<div class="timeline"><div class="property-history-content-container"><div class="timeline-content"><h4 class="section-header col-12">Today</h4><div class="sold-row row PropertyHistoryEventRow" id="propertyHistory-0"><div class="col-4"><p>Oct 15, 2020</p><p class="subtext">Date</p></div><div class="description-col col-4"><div>Sold (MLS) (Closed)</div><div></div><p class="subtext">ACTRIS #5085856</p></div><div class="col-4"><div class="price-col number">$302,000<span class="number empty"> </span></div><p class="subtext">Price</p></div></div><div class=" row PropertyHistoryEventRow" id="propertyHistory-1"><div class="col-4"><p>Sep 16, 2020</p><p class="subtext">Date</p></div><div class="description-col col-4"><div>Contingent (Active Under Contract)</div><div></div><p class="subtext">ACTRIS #5085856</p></div><div class="col-4"><div class="price-col number">—<span class="number empty"> </span></div><p class="subtext">Price</p></div></div><div class=" row PropertyHistoryEventRow" id="propertyHistory-2"><div class="col-4"><p>Sep 8, 2020</p><p class="subtext">Date</p></div><div class="description-col col-4"><div>Pending (Pending - Taking Backups)</div><div></div><p class="subtext">ACTRIS #5085856</p></div><div class="col-4"><div class="price-col number">—<span class="number empty"> </span></div><p class="subtext">Price</p></div></div><div class=" row PropertyHistoryEventRow" id="propertyHistory-3"><div class="col-4"><p>Sep 5, 2020</p><p class="subtext">Date</p></div><div class="description-col col-4"><div>Listed (Active)</div><div></div><p class="subtext">ACTRIS #5085856</p></div><div class="col-4"><div class="price-col number">$294,900<span class="number empty"> </span></div><p class="subtext">Price</p></div></div></div></div></div>
"""

soup=BeautifulSoup(html,'html.parser')

soup.find('div', class_='timeline-content').find('div', class_='price-col number').text

输出

$302,000
