                  问题描述

                  我正在尝试使用python和Selenium从此div内部的span中获取文本:

                  <div class="product-name">
                      <span class="h1" itemprop="name">TEXT</span>
                  </div>
                  

                  我尝试过此操作,但返回空字符串:

                  line = dr.find_element_by_class_name('product-name').find_element_by_xpath('.//span').text
                  

                  提前感谢,

                  推荐答案

                  您应该尝试使用css_selector在一条Find语句中查找Desire元素,如下所示:-

                  line = dr.find_element_by_css_selector('div.product-name > span').text
                  

                  如果您仍然收到空字符串,请尝试使用get_attribute("textContent")As:-

                  line = dr.find_element_by_css_selector('div.product-name > span').get_attribute("textContent")
                  

                  或使用get_attribute("innerHTML")AS:-

                  line = dr.find_element_by_css_selector('div.product-name > span').get_attribute("innerHTML")
                  

                  注意:-如果只有需要的文本,也可以使用class_name在父元素<div>上使用上述操作获取innerText:-

                  line = dr.find_element_by_class_name('product-name').text
                  

                  line = dr.find_element_by_class_name('product-name').get_attribute("textContent")
