本地HTML文件刮擦Urllib和BeautifulSoup

Question

我對python非常陌生，並且已經從頭開始研究以下代碼兩週來抓取本地文件。大概有將近一百個小時，我可以儘可能多地學習Python，版本，導入包如lxml，bs4，請求，urllib，os，glob等等。

我毫無希望地停留在第一部分中，在一個目錄中獲取12,000個具有奇怪名稱的HTML文件，以加載和分析BeautifulSoup。我想將所有這些數據都放到一個csv文件中，或者只是爲了輸出，所以我可以使用剪貼板將它複製到一個文件中。

import bs4 
from urllib.request import urlopen as uReq 
from bs4 import BeautifulSoup as soup 

#THIS LOCAL FILE WORKS PERFECTLY. I HAVE 12,000 HTML FILES IN THIS DIRECTORY TO PROCESS. HOW? 
#my_url = 'file://127.0.0.1/C:\\My Web Sites\\BioFachURLS\\www.organic-bio.com\\en\\company\\1-SUNRISE-FARMS.html' 
my_url = 'http://www.organic-bio.com/en/company/23694-MARTHOMI-ALLERGY-FREE-FOODS-GMBH' 

uClient = uReq(my_url) 
page_html = uClient.read() 
uClient.close() 

# html parsing 
page_soup = soup(page_html, "html.parser") 

# grabs each field 
contactname = page_soup.findAll("td", {"itemprop": "name"}) 
contactstreetaddress = page_soup.findAll("td", {"itemprop": "streetAddress"}) 
contactpostalcode = page_soup.findAll("td", {"itemprop": "postalCode"}) 
contactaddressregion = page_soup.findAll("td", {"itemprop": "addressRegion"}) 
contactaddresscountry = page_soup.findAll("td", {"itemprop": "addressCountry"}) 
contactfax = page_soup.findAll("td", {"itemprop": "faxNumber"}) 
contactemail = page_soup.findAll("td", {"itemprop": "email"}) 
contactphone = page_soup.findAll("td", {"itemprop": "telephone"}) 
contacturl = page_soup.findAll("a", {"itemprop": "url"}) 

#Outputs as text without tags 
Company = contactname[0].text 
Address = contactstreetaddress[0].text 
Zip = contactpostalcode[0].text 
Region = contactaddressregion[0].text 
Country = contactaddresscountry[0].text 
Fax = contactfax[0].text 
Email = contactemail[0].text 
Phone = contactphone[0].text 
URL = contacturl[0].text 

#Prints with comma delimiters 

print(Company + ', ' + Address + ', ' + Zip + ', ' + Region + ', ' + Country + ', ' + Fax + ', ' + Email + ', ' + URL)

我一直在運行通過文件夾與之前的一堆文件，所以我可以建議一點幫助。

我們將與循環開始將文件從文件夾

import os 
from bs4 import BeautifulSoup as soup 
phone = [] # A list to store all the phone 
path = 'yourpath' # This is your folder name which stores all your html 
#be careful that you might need to put a full path such as C:\Users\Niche\Desktop\htmlfolder 
for filename in os.listdir(path): #Read files from your path 
    #Here we are trying to find the full pathname 
    for x in filename: #We will have A-H stored as path 
      subpath = os.path.join(path, filename) 
      for filename in os.listdir(subpath): 
      #Getting the full path of a particular html file 
       fullpath = os.path.join(subpath, filename) 
       #If we have html tag, then read it 
       if fullpath.endswith('.html'): continue 
       #Then we will run beautifulsoup to extract the contents 
        soup = BeautifulSoup(open(fullpath), 'html.parser') 
        #Then run your code 
        # grabs each field 
        contactname = page_soup.findAll("td", {"itemprop": "name"}) 
        contactstreetaddress = page_soup.findAll("td", {"itemprop": "streetAddress"}) 
        contactpostalcode = page_soup.findAll("td", {"itemprop": "postalCode"}) 
        contactaddressregion = page_soup.findAll("td", {"itemprop": "addressRegion"}) 
        contactaddresscountry = page_soup.findAll("td", {"itemprop": "addressCountry"}) 
        contactfax = page_soup.findAll("td", {"itemprop": "faxNumber"}) 
        contactemail = page_soup.findAll("td", {"itemprop": "email"}) 
        contactphone = page_soup.findAll("td", {"itemprop": "telephone"}) 
        contacturl = page_soup.findAll("a", {"itemprop": "url"}) 

        #Outputs as text without tags 
        Company = contactname[0].text 
        Address = contactstreetaddress[0].text 
        Zip = contactpostalcode[0].text 
        Region = contactaddressregion[0].text 
        Country = contactaddresscountry[0].text 
        Fax = contactfax[0].text 
        Email = contactemail[0].text 
        Phone = contactphone[0].text 
        URL = contacturl[0].text 
        #Here you might want to consider using dictionary or a list 
        #For example append Phone to list call phone 
        phone.append(Phone) 

的代碼是一個有點亂，但它通過所有可能的文件夾中運行（即使你有你的主文件夾內的其他文件夾），那麼試着找html標籤，打開它。

我會建議使用與公司的dicitonary作爲一個關鍵，我認爲公司的名稱是不同的。一堆列表也會很好，因爲你的價值將被相應地排序。我對字典不太擅長，所以我不能給你提供更多的建議。我希望我能回答你的問題。

對不起，代碼亂了。
