Python pyquery使用

import requests
from pyquery import PyQuery as pq


url = ‘‘
headers = {}
# resp_text = requests.get(url=url, headers=headers).text
resp_text = requests.get(url=url, headers=headers).content
doc_resp = pq(resp_text)
a = doc_resp("#wrap")  # id用法
b = doc_resp(".wrap")  # class用法 中间有空格的用.替代
c = doc_resp(".wrap").attr(‘href‘)  # 获取href属性
e = doc_resp(".wrap").text()  # 获取文本
f = doc_resp(".wrap").parent()  # 父元素
g = doc_resp(".wrap").siblings()  # 兄弟元素
h = doc_resp(".wrap").html()  # html信息
i = doc_resp(".wrap").remove(‘ul‘)  # 移除标签
# 遍历查找结果
result_items = doc_resp(".wrap").items()
for result_item in result_items:
    print(result_items)
# 选择标签
html = ‘‘
doc = pq(html)
its=doc("link:first-child")
print(‘第一个标签:%s‘%its)
its=doc("link:last-child")
print(‘最后一个标签:%s‘%its)
its=doc("link:nth-child(2)")
print(‘第二个标签:%s‘%its)
its=doc("link:gt(0)") #从零开始
print("获取0以后的标签:%s"%its)
its=doc("link:nth-child(2n-1)")
print("获取奇数标签:%s"%its)
its=doc("link:contains(‘hello‘)")
print("获取文本包含hello的标签:%s"%its)
