如何用python从以下代码中，获取到src后面的地址，感谢。 <span class="yanzhengimg"> <img id="login_verify_code_img" src="/bis/user/verifyCodeImg?0.0544816582801837"> </span>
利用xpath抓取
from lxml.html import fromstring html = '''<span class="yanzhengimg"> <img id="login_verify_code_img" src="/bis/user/verifyCodeImg?0.0544816582801837"> </span>''' tree = fromstring(html) src = tree.xpath('//img[@id="login_verify_code_img"]/@src')[0]
