我正在尝试访问一个元素
<script type="text/javascript">ReportPopper("http://asd.asd.asd/ReportOutput/asd-asd-41cc-asd-asd.xls");<script>
使用Beautifulsoup,不幸的是,我不确定如何访问ReportPopper部分并将其分配给使用Python的变量
抱歉,如果已经回答.
我尝试在find(‘ReportPopper’)中添加ReportPopper并给我一个none元素.
import requests
import io
import os
from bs4 import BeautifulSoup
participation = requests.post(url=report_post_url,data=request_post_report_form,headers=report_post_headers,stream=True)
print(participation)
soup = BeautifulSoup(participation.text,'html.parser')
for n in soup.find_all('script'):
javascript = n['ReportPopper']
print(javascript)
我想得到的最终结果是：
javascript =“ http：//asd.asd.asd/ReportOutput/asd-asd-41cc-asd-asd.xls”
作为我的输出：
Traceback (most recent call last):
File "c:\Users\John asd\Documents\GitHub\asd.net\testing.py",line 184,in <module>
javascript = n['ReportPopper']
File "C:\Users\John asd\asd\Local\Programs\Python\Python37\lib\site-packages\bs4\element.py",line 1016,in __getitem__
return self.attrs[key]
KeyError: 'ReportPopper'
最佳答案
尝试这个：
re.compile()返回regular expression object,这意味着h是一个正则表达式对象.
regex对象具有自己的match方法,该方法带有可选的pos和endpos参数：
regex.match(string[,pos[,endpos]])
from bs4 import BeautifulSoup
import re
html = """<script>ReportPopper("http://asd.asd.asd/ReportOutput/asd-asd-41cc-asd-asd.xls");</script>"""
soup = BeautifulSoup(html,'lxml')
script = soup.find_all("script")
pattern = re.compile('ReportPopper(.*);')
for i in script:
strObj = i.text
match = pattern.search(strObj)
if match:
print(strObj.split("ReportPopper(")[1][:-2])
O / P：
"http://asd.asd.asd/ReportOutput/asd-asd-41cc-asd-asd.xls"
