Python/Selenium如何从内容中提取文本？

Question

我想从网站的人员列表中提取bios： https://blueprint.connectiv.com/speakers/

我想摘录他们的头衔、公司和简历。但是，只有当您单击网站上的每张照片时，bio才可用。

下面是我提取标题的代码&；公司：

driver.find_element_by_xpath("//*[@id='speakers']/div/div/div/div/div/div/div").text.split('\n')

有人能帮我提取每个人的bios吗？任何建议都将不胜感激

Answer 1

如果您要查找的所有信息都在一个段落标记<p>内，该标记具有一个类bio（so <p class='bio'>），并且源代码中已经存在所有模态，那么您只需使用以下选项选择all：

bios = driver.find_elements_by_xpath('//p[@class="bio"]') 

它将选择作为<p>标记的所有元素，该标记也有一个等于'bio'的类，并在列表中返回它。如果某些p标记中有其他类（即<p class='bio someotherclass'>），则需要在xpath中使用contains（）方法，如下所示：

bios = driver.find_elements_by_xpath('//p[contains(@class, "bio")]') 

然后，您可以像这样循环查看结果：

for bio in bios:
    print(bio.text)

Answer 2

您不必单击图像，因为每个扬声器的所有模态都已在源中完全填充。您可以使用driver.execute_script从这些模态中提取内容：

from selenium import webdriver
d = webdriver.Chrome('/path/to/chromedriver')
d.get('https://blueprint.connectiv.com/speakers/')
results = d.execute_script("""
  var people = [];
  for (var i of document.querySelectorAll('.modal.speakerCard')){
     people.push({
        name:i.querySelector('.description h4').textContent,
        title:i.querySelector('p.title').textContent,
        company:i.querySelector('p.company').textContent,
        bio:i.querySelector('p.bio').textContent,
     });
  }
  return people;
""")
