如何生成 HTML 文档中文本字符串的所有路径，最好使用 BeautifulSoup？我有这个代码：

<DIV class="art-info"><SPAN class="time"><SPAN class="time-date" content="2012-02-28T14:46CET" itemprop="datePublished">
             28. february 2012
            </SPAN>
            14:46
           </SPAN></DIV><DIV>
           Something,<P>something else</P>continuing.
          </DIV>

我想将 HTML 代码划分为文本字符串的路径，例如

str1 >>>  <DIV class="art-info"><SPAN class="time"><SPAN class="time-date" content="2012-02-28T14:46CET" itemprop="datePublished">28. february 2012</SPAN></SPAN></DIV>
str2 >>>  <DIV class="art-info"><SPAN class="time">14:46</SPAN></DIV>
str3 >>>  <DIV>Something,continuing.</DIV>
str4 >>>  <DIV><P>something else</P></DIV>

或者

str1 >>>  <DIV><SPAN><SPAN>28. february 2012</SPAN></SPAN></DIV>
str2 >>>  <DIV><SPAN>14:46</SPAN></DIV>
str3 >>>  <DIV>Something,continuing.</DIV>
str4 >>>  <DIV><P>something else</P></DIV>

或者 

str1 >>>  //div/span/span/28. february
str2 >>>  //div/span/14:46
str3 >>>  //div/Something,continuing.
str4 >>>  //div/p/something else

我研究了 BeautifulSoup 文档，但我不知道该怎么做。你有什么想法？

from bs4 import BeautifulSoup
import re
file=open("input")
soup = BeautifulSoup(file)
for t in soup(text=re.compile(".")):
  path = '/'.join(reversed([p.name for p in t.parentGenerator() if p]))
  print path+"/"+ t.strip()

输出

[document]/html/body/div/span/span/28. february 2012
[document]/html/body/div/span/14:46
[document]/html/body/div/Something,
[document]/html/body/div/p/something else
[document]/html/body/div/continuing.
