从Selenium for Python中具有相同类的多个元素中获取文本? [英] Get the text from multiple elements with the same class in Selenium for Python?

问题描述

我正在尝试从具有JavaScript加载内容的页面上抓取数据.例如，我想要的内容具有以下格式:

I'm trying to scrape data from a page with JavaScript loaded content. For example, the content I want is in the following format:

<span class="class">text</span>
...
<span class="class">more text</span>

我使用了find_element_by_xpath(//span[@class="class"]').text函数，但它仅返回指定类的第一个实例.基本上，我想要一个类似[text, more text]的列表.我找到了find_elements_by_xpath()函数，但是最后的.text导致错误exceptions.AttributeError: 'list' object has no attribute 'text'.

I used the find_element_by_xpath(//span[@class="class"]').text function but it only returned the first instance of the specified class. Basically, I would want a list like [text, more text] etc. I found the find_elements_by_xpath() function, but the .text at the end results in an error exceptions.AttributeError: 'list' object has no attribute 'text'.

推荐答案

find_element_by_xpath返回一个具有text属性的元素.

find_element_by_xpath returns one element, which has text attribute.

find_elements_by_xpath()返回所有匹配的元素，这是一个列表，因此您需要遍历并获取每个元素的text属性.

find_elements_by_xpath() returns all matching elements, which is a list, so you need to loop through and get text attribute for each of the element.

all_spans = driver.find_elements_by_xpath("//span[@class='class']")
for span in all_spans:
    print span.text

请参阅Selenium Python API文档此处有关find_elements_by_xpath(xpath)的更多详细信息.
