【解决方案1】：

我们的想法是制作一个很好的可重用函数，它将字段名称作为参数并输出字段值。该函数将搜索strong 元素，其中text 以传入的字段名称和get the next sibling 开头：

from bs4 import BeautifulSoup

data = """
<div>
    <span class="JamalsinRed">H.S. AHMED ALLY</span>
    <hr align="left" width="400" color="#CCCCCC">
      <strong>Address : </strong>217/7,Saleh Market,Adamjee Road,Saddar<br>
      <strong>City : </strong>Rawalpindi<br>
      <strong>Phone # : </strong>(92 51) 5511748, 5125396<br>
      <strong>Fax : </strong>(92 51) 5511749<br>
      <strong>E-mail : </strong><a class=b href='mailto:hsaforce@cyber.net.pk'>hsaforce@cyber.net.pk</a><br><strong>Web : </strong>
      <a target=_blank href='http://www.hsahmedally.com'>www.hsahmedally.com</a><br>
    </hr>
</div>
"""

def get_field_value(soup, field):
    return soup.find('strong', text=lambda x: x.startswith(field)).next_sibling

soup = BeautifulSoup(data)
print get_field_value(soup, 'Address')
print get_field_value(soup, 'City')

打印：

217/7,Saleh Market,Adamjee Road,Saddar
Rawalpindi
