使用BeautifulSoup从文本/ html文档获取干净的文本

Question

我有一个文档有两种内容类型：text/xml和text/html。我想用BeautifulSoup来解析文档，并最终得到一个干净的文本版本。该文档以元组的形式开始，因此我一直使用repr将其变成BeautifulSoup识别的内容，然后使用find_all通过搜索div来查找文档的文本/ html位，如下所示：

soup = BeautifulSoup(repr(msg_data)) 
text = soup.html.find_all("div") 

然后，我将文本转换回字符串，将其保存到一个变量，然后把它放回汤对象并调用get_text就可以了，就像这样：

str_text = str(text) 
soup_text = BeautifulSoup(str_text) 
soup_text.get_text() 

然而，然后改变编码为unicode，如下所示：

u'[9:16 PM\xa0Erica: with images, \xa0\xa0and that seemed long to me anyway, 9:17  
PM\xa0me: yeah, \xa0Erica: so feel free to make it shorter, \xa0\xa0or rather, please do, 
9:18 PM\xa0nobody wants to read about that shit for 2 pages, \xa0me: :), \xa0Erica: while 
browsing their site, \xa0me: srsly, \xa0Erica: unless of course your writing is magic, 
\xa0me: My writing saves drowning puppies, \xa0\xa0Just plucks him right out and gives 
them a scratch behind the ears and some kibble, \xa0Erica: Maine is weird, \xa0me: haha]' 

当我试图重新编码为UTF-8，像这样：

soup.encode('utf-8') 

我回未解析类型。

我想让我把干净的文本保存为一个字符串，然后我可以在文本中找到特定的东西（例如，上面的文本中的“小狗”）。

基本上，我在这里跑来跑去。谁能帮忙？与往常一样，非常感谢您为您提供的任何帮助。

编码不被破坏;这正是它应该的。 '\xa0'是非破坏性空间的Unicode。

如果你想这个（Unicode）的字符串作为ASCII编码，你可以告诉编解码器忽略任何字符不理解：

>>> x = u'[9:16 PM\xa0Erica: with images, \xa0\xa0and that seemed long to me anyway, 9:17 PM\xa0me: yeah, \xa0Erica: so feel free to make it shorter, \xa0\xa0or rather, please do, 9:18 PM\xa0nobody wants to read about that shit for 2 pages, \xa0me: :), \xa0Erica: while browsing their site, \xa0me: srsly, \xa0Erica: unless of course your writing is magic, \xa0me: My writing saves drowning puppies, \xa0\xa0Just plucks him right out and gives them a scratch behind the ears and some kibble, \xa0Erica: Maine is weird, \xa0me: haha]' 
>>> x.encode('ascii', 'ignore') 
'[9:16 PMErica: with images, and that seemed long to me anyway, 9:17 PMme: yeah, Erica: so feel free to make it shorter, or rather, please do, 9:18 PMnobody wants to read about that shit for 2 pages, me: :), Erica: while browsing their site, me: srsly, Erica: unless of course your writing is magic, me: My writing saves drowning puppies, Just plucks him right out and gives them a scratch behind the ears and some kibble, Erica: Maine is weird, me: haha]'
