我正在使用 beautifulsoup 并想从网页上的两个单词之间提取所有文本。

例如，想象以下网站文本：

This is the text of the webpage. It is just a string of a bunch of stuff and maybe some tags in between.

我想拉出页面上以 . 开头text和结尾的所有内容bunch。

在这种情况下，我只想要：

text of the webpage. It is just a string of a bunch

但是，一个页面上可能有多个这样的实例。

做这个的最好方式是什么？

这是我目前的设置：

#!/usr/bin/env python
from mechanize import Browser
from BeautifulSoup import BeautifulSoup

mech = Browser()
urls = [
http://ca.news.yahoo.com/forget-phoning-business-app-sends-text-instead-100143774--sector.html
    ]



   for url in urls:
        page = mech.open(url)
        html = page.read()
        soup = BeautifulSoup(html)
        text= soup.prettify()
            texts = soup.findAll(text=True) 

    def visible(element):
        if element.parent.name in ['style', 'script', '[document]', 'head', 'title']: 
        # If the parent of your element is any of those ignore it

            return False

        elif re.match('<!--.*-->', str(element)):
        # If the element matches an html tag, ignore it

            return False

        else:
        # Otherwise, return True as these are the elements we need

          return True

    visible_texts = filter(visible, texts)
    # Filter only returns those items in the sequence, texts, that return True. 
    # We use those to build our final list.

    for line in visible_texts:
      print line

因为您只是在解析文本，所以您只需要正则表达式：

import re
result = re.findall("text.*?bunch", text_from_web_page)
