1、构造webdriver启动方法

driver = webdriver.Chrome()
base_url = "https://movie.douban.com/subject/26100958/"
driver.get(base_url)

2、保存完整HTML代码

print(driver.page_source)

3、保存部分HTML代码，及其他方法

# 定位至节点
elem = driver.find_element(By.ID, "info")
htm_dat = elem.get_property("outerHTML")

print('获取节点的html源码：', htm_dat)

htm_name = elem.get_property("nodeName")

print('节点名称：', htm_name)

htm_type = elem.get_property("nodeType")

print('节点类型：', htm_type)

htm_ght = elem.get_property("clientHeight")

print('节点实际高度：', htm_ght)

htm_dth = elem.get_property("clientWidth")

print('节点实际宽度：', htm_dth)

htm_node_name = elem.get_property("parentNode").get_property("nodeName")

print('该节点的父节点.名称：', htm_node_name)

htm_next_htm = elem.get_property("nextSibling").get_property("outerHTML")

print('该节点的相邻的下一个节点.源码：', htm_next_htm)
