Python文本解析两个单词之间

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

例如,想象以下网站文字:

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

我想提取页面上以text开头并以bunch结尾的所有内容。

在这种情况下,我只想要:

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

但是,页面上可能存在多个此类实例。

这样做的最佳方式是什么?

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

因为您只需解析文本,所以只需要正则表达式:

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