主要是循环节的使用，复制html改为了复制xpath，
-
出现这种明显带有分隔符性的要素，

程序当中，在整体处，即红圈处，加[0]的原因。
name=info.xpath('div[2]/p[2]/span/text()')[0] #[0]为什么要加？
name1=name.split('-')[0]
name2 = name.split('-')[1]

2.在 后面加[0]，区别就是在下方显示的是否带有[]符号

关于灰色部分，还需弄清楚原因

- 存取需要像之前正则一样，重新定义函数
未存取定义函数之前
import requests
from lxml import etree
headers = {
'User-Agent':'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36'
}
url='https://xiaoyuan.zhaopin.com/full/industry/0/0_0_0_0_-1_0_1_0'
res = requests.get(url, headers=headers)
html = etree.HTML(res.text)
infos = html.xpath('//ul[@class="searchResultListUl"]/li')
for info in infos:
# rank_1=info.xpath('span[3]')[0]
# rank=rank_1.xpath('string(.)').strip()
name=info.xpath('div[2]/p[2]/span/text()')[0] #[0]为什么要加？
name1=name.split('-')[0]
name2 = name.split('-')[1]
job=info.xpath('div[2]/p[1]/a/text()')[0]
place=info.xpath('div[2]/p[3]/span[1]/span/em/text()')[0]
job_type=info.xpath('div[2]/p[4]/span[4]/span/em/text()')
print(name1,name2,job,place,job_type)
存取定义函数之后
-
正则定义函数之后

xpath定义函数之后

- 完善之后完整代码
