在这种特殊情况下,您可以解析您已经能够使用脚本收集的样式字符串。
只需将此功能添加到您的代码中:
def parse_style_attribute(style_string):
if 'background-image' in style_string:
style_string = style_string.split(' url("')[1].replace('");', '')
return style_string
return None
这是一个简单的字符串解析,如果有" background-image"则会提取网址。在字符串中,如果没有图像则返回None。
然后您可以在代码中使用它:
links = list()
for ii in driver.find_elements_by_xpath('//a[@style]'):
o = ii.get_attribute('style')
links.append(parse_style_attribute(o))
links = [link for link in links if link is not None]
