Question

我正在尝试从div获取姓名和联系电话，并且div具有三个跨度，但是问题是div有时只有一个跨度，有时是两个且有时是三个跨度。

第一个跨度有名称。
第二个跨度还有其他数据。
第三跨有联系电话

这是HTML

<div class="ds-body-small" id="yui_3_18_1_1_1554645615890_3864">
 <span class="listing-field" id="yui_3_18_1_1_1554645615890_3863">beth 
 budinich</span>
 <span class="listing-field"><a href="http://Www.redfin.com" 
 target="_blank">See listing website</a></span>
 <span class="listing-field" id="yui_3_18_1_1_1554645615890_4443">(206) 
 793-8336</span>
</div>

这是我的代码

try:
  name= browser.find_element_by_xpath("//span[@class='listing-field'][1]")
  name = name.text.strip()
  print("name : " + name)
except:
  print("Name are missing")
  name = "N/A"

try:
  contact_info= browser.find_element_by_xpath("//span[@class='listing- 
  field'][3]")
  contact_info = contact_info.text.strip()
  print("contact info : " + contact_info)
except:
  print("contact_info are missing")
  days = "N/A"

我的代码没有给我正确的结果。谁能为我提供最佳解决方案。谢谢

Answer 1

您可以迭代引发联系人并检查是否有子a元素以及是否匹配电话号码模式：

contacts = browser.find_elements_by_css_selector("span.listing-field")

contact_name = []
contact_phone = "N/A"
contact_web = "N/A"

for i in range(0, len(contacts)):
    if len(contacts[i].find_elements_by_tag_name("a")) > 0:
        contact_web = contacts[i].find_element_by_tag_name("a").get_attribute("href")
    elif re.search("\\(\\d+\\)\\s+\\d+-\\d+", contacts[i].text):
        contact_phone = contacts[i].text
    else:
        contact_name.append(contacts[i].text)

contact_name = ", ".join(contact_name) if len(contact_name) > 0 else "N/A"

输出：

contact_name：['Kevin Howard'，'Howard enterprise']
contact_phone：'（206）334-8414'

页面上有验证码。为了更好地使用requests，所有信息均以json格式提供。

</div>'''
# the given sample html is stored as a input in variable called "text"
soup = BeautifulSoup(text,"html.parser")
main = soup.find(class_="listing-field")
# Now the spans with class name "listing-field" is stored as list in "main"
print main[0].text
# it will print the first span element
print main[-1].text
# it will print the last span element
