Python、Beautiful Soup：如何获取想要的元素

Question

我正在尝试到达某个元素，解析站点的源代码。这是我试图解析的部分的片段（这里直到周五），但它在一周中的所有日子都是一样的

<div id="intForecast">
    <h2>Forecast for Rome</h2>
    <table cellspacing="0" cellpadding="0" id="nonCA">
        <tr>
            <td onclick="showDetails('1');return false" id="day1" class="on">
                <span>Thursday</span>
                <div class="intIcon"><img src="http://icons.wunderground.com/graphics/conds/2005/sunny.gif" alt="sunny" /></div>
                <div>Clear</div>
                <div><span class="hi">H <span>22</span>&deg;</span> / <span class="lo">L <span>11</span>&deg;</span></div>
            </td>
            <td onclick="showDetails('2');return false" id="day2" class="off">
                <span>Friday</span>
                <div class="intIcon"><img src="http://icons.wunderground.com/graphics/conds/2005/partlycloudy.gif" alt="partlycloudy" /></div>
                <div>Partly Cloudy</div>
                <div><span class="hi">H <span>21</span>&deg;</span> / <span class="lo">L <span>15</span>&deg;</span></div>
            </td>
        </tr>
    </table>
</div>

.....所有日子等等

实际上我得到了我的结果，但我认为以一种丑陋的方式：

forecastFriday= soup.find('div',text='Friday').findNext('div').findNext('div').string

现在，如您所见，我深入研究重复 .findNext('div') 的元素，最终到达 .string

我想获取周五"Partly Cloudy"的信息

那么还有更多的 pythonic 方法来做到这一点吗？谢谢！

Answer 1

只需找到所有 <td> 并遍历它们：

soup = BeautifulSoup(your_html)
div = soup('div',{'id':'intForecast'})[0]
tds = div.find('table').findAll('td')

for td in tds:
    day = td('span')[0].text
    forecast = td('div')[1].text
    print day, forecast
