Python 如何抓取图像、文本和指向音频文件 url 的链接

Question

我正在尝试从以下网址(http://www.ancient-hebrew.org/m/dictionary/1000.html)中抓取数据。

因此，每个希伯来语单词部分都以 img url 开头，后跟 2 个文本，即实际的希伯来语单词及其发音。例如，url中的第一个条目是以下"img1 img2 img3 אֶלֶף e-leph"希伯来语是使用wget下载html后的Unicode

我正在尝试收集这些信息，以便首先获得图像文件，然后是希伯来语单词，然后是发音。最后，我想找到音频文件的URL。

此外，每个单词的每一行似乎都以

我是网络抓取的新手，所以以下是我所能做的。

from urllib.request import urlopen
from bs4 import BeautifulSoup
url = '1000.html'
try:
page = urlopen(url)
except:
print("Error opening the URL")
soup = BeautifulSoup(page, 'html.parser')
content = soup.find('<!--501-1000-->', {"<A Name= "})
images = ''
for i in content.findAll('*.jpg'):
images = images + ' ' +  i.text
with open('scraped_text.txt', 'w') as file:
file.write(images)

如您所见，我的代码并没有真正完成这项工作。最后，我想获取URL中每个单词的信息，并将其保存为文本文件或json文件，以较容易者为准。

例如 images： URLsOfImages， HebrewWord： txt， 发音： txt， URLtoAudio： txt

对于下一个词等等。

我写了一个脚本，应该可以帮助你。它包含您要求的所有信息。由于希伯来字母，这不能另存为 json 文件，否则它会被存储为字节。我知道你不久前发布了这个问题，但我今天找到了它并决定试一试。无论如何，这里是：

import requests
from bs4 import BeautifulSoup
import re
import json

url = 'http://www.ancient-hebrew.org/m/dictionary/1000.html'
page = requests.get(url)
soup = BeautifulSoup(page.text, 'html.parser')
def images():
#Gathers all the images (this includes unwanted gifs)
imgs = soup.find_all('img')
#Gets the src attribute to form the full url
srcs = [img['src'] for img in imgs]
base_url = 'https://www.ancient-hebrew.org/files/'
imgs = {}
section = 0
#Goes through each source of all the images
for src in srcs:
#Checks if it is a gif, these act as a separator
if src.endswith('.gif'):
#If it is a gif, change sections (acts as separator)
section += 1
else:
#If it is a letter image, use regex to extract the part of src we want and form full url
actual_link = re.search(r'files/(.+.jpg)', src)
imgs.setdefault(section, []).append(base_url + actual_link.group(1))
return imgs
def hebrew_letters():
#Gets hebrew letters, strips whitespace, reverses letter order since hebrew letters get messed up
h_letters = [h_letter.text.strip() for h_letter in soup.find_all('font', attrs={'face': 'arial'})]
return h_letters
def english_letters():
#Gets english letters by regex, this part was difficult because these letters are not surrounded by tags in the html
letters = ''.join(str(content) for content in soup.find('table', attrs={'width': '90%'}).td.contents)
search_text = re.finditer(r'/font>s+(.+?)s+<br/>', letters)
e_letters = [letter.group(1) for letter in search_text]
return e_letters
def get_audio_urls():
#Gets all the mp3 hrefs for the audio part
base_url = 'https://www.ancient-hebrew.org/m/dictionary/'
links = soup.find_all('a', href=re.compile(r'd+s*.mp3$'))
audio_urls = [base_url+link['href'].replace('t','') for link in links]
return audio_urls
def main():
#Gathers scraped data
imgs = images()
h_letters = hebrew_letters()
e_letters = english_letters()
audio_urls = get_audio_urls()
#Encodes data into utf-8 (due to hebrew letters) and saves it to text file
with open('scraped_hebrew.txt', 'w', encoding='utf-8') as text_file:
for img, h_letter, e_letter, audio_url in zip(imgs.values(), h_letters, e_letters, audio_urls):
text_file.write('Image Urls: ' + ' - '.join(im for im in img) + 'n')
text_file.write('Hebrew Letters: ' + h_letter + 'n')
text_file.write('English Letters: ' + e_letter + 'n')
text_file.write('Audio Urls: ' + audio_url + 'nn')

main()
