获取网页后，如何使用Xpath解析html界面。

获取网页后，如何使用Xpath解析html界面。

解析html文件两种方式

html = etree.HTML(res2.text) # 读取程序里的,变成可解析的层级对象

etree.parse(‘名字.html’,etree.HTMLParser()) #读取文件里的

string（.）

这个图是截屏的下面链接文章作者的

看到的用string【.】来拼接的文章

获取某页面以及用Xpath解析后数据（代码详情，如果有可优化的地方，希望看到的大佬可以帮我指出）

url2 = "略"

headers2 = {略}
res2 = requests.get(url=url,headers=headers2)
res2.encoding = 'utf-8'
time.sleep(5)
#print(res2.url)
#print(res2.status_code)
#房屋价格
html = etree.HTML(res2.text)  # 读取程序里的,变成可解析的层级对象
house_price = html.xpath('//div[@class="property-price"]/p[@class="property-price-total"]/span[@class="property-price-total-num"]/text()')
print("房屋价格：", house_price)
house_price_m = html.xpath('//div[@class="property-price"]/p[@class="property-price-average"]/text()')
print("房屋每平米价格：", house_price_m)

# time.sleep(5)
#房子地址
house_dizhiqian = html.xpath('//section[@class="list-left"]//section[2]//div[@class="property-content"]//div['
							 '@class="property-content-info property-content-info-comm"]/p/text()')
house_dizhihou = html.xpath('//section[@class="list-left"]//section[2]//div[@class="property-content"]//div['
							'@class="property-content-info property-content-info-comm"]/p/span/text()')
print("house_dizhiqian:", house_dizhiqian)
print("house_dizhihou:", house_dizhihou)

#存储数据
house_info = {
	'house_name':house_name,
	'house_hx_qian': house_hx_qian,
	'house_hx_hou': house_hx_hou,
	'house_price':house_price,
	'house_price_m':house_price_m,
	'house_dizhiqian':house_dizhiqian,
	'house_dizhihou':house_dizhihou
}
fd = pd.DataFrame.from_dict(house_info,orient='index')
fd = fd.T
fd.to_csv("文件名.csv",header=True)
