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)

其他方案1：BeautifulSoup

安装：pip3 install beautifulsoup4
	 pip install lxml

其他方案2：lxml库中etree.HTML()

安装：pip install bs4
	 pip install lxml
	 pip install html5lib
