问题描述

想要制定一个可以从 rect 标签中获取属性Style"的 Xpath 表达式.我写了以下代码但不起作用.

Want to formulate an Xpath expression that can get attribute "Style" from the rect tag. I wrote the following code but doesn't work.

此外，在获得 Style 属性后，我只想要 rgb();文本.我该怎么做?

Also, after getting the Style attribute I only want the rgb(); text. How can I do this?

谢谢

   for element in driver.find_elements_by_css_selector("#workload-analysis-chart > div > svg > g"):
            style = element.get_attribute('style')
            print style

推荐答案

您可以通过 xpath 使用 find_element_by_xpath() 然后获取style 属性使用 get_attribute() 方法:

You can find the element by xpath using find_element_by_xpath() and then get the style attribute using get_attribute() method:

rect = driver.find_element_by_xpath('//div[@id="workload-analysis-chart"]/div/svg/g/g[@data-selected="true"]/rect')
print rect.get_attribute('style')
