Suggestions on get_text() in BeautifulSoup
提问by user601836
I am using BeautifulSoup to parse some content from a html page.
我正在使用 BeautifulSoup 来解析 html 页面中的一些内容。
I can extract from the html the content I want (i.e. the text contained in a spandefined by the classmyclass).
我可以从 html 中提取我想要的内容（即包含在span由classmyclass定义的a 中的文本）。
result = mycontent.find(attrs={'class':'myclass'})
I obtain this result:
我得到这个结果：
<span class="myclass">Lorem ipsum<br/>dolor sit amet,<br/>consectetur...</span>
If I try to extract the text using:
如果我尝试使用以下方法提取文本：
result.get_text()
I obtain:
我获得：
Lorem ipsumdolor sit amet,consectetur...
As you can see when the tag <br>is removed there is no more spacing between the contents and two words are concated.
正如您所看到的，当标签<br>被移除时，内容之间没有更多的间距，两个单词被连接起来。
How can I solve this issue?

Use 'contents' , then replace <br>?
使用 'contents' ，然后替换<br>?
Here is a full (working, tested) example:
这是一个完整的（工作的，经过测试的）示例：
from bs4 import BeautifulSoup
import urllib2
url="http://www.floris.us/SO/bstest.html"
page=urllib2.urlopen(url)
soup = BeautifulSoup(page.read())
result = soup.find(attrs={'class':'myclass'})
print "The result of soup.find:"
print result
print "\nresult.contents:"
print result.contents
print "\nresult.get_text():"
print result.get_text()
for r in result:
if (r.string is None):
r.string = ' '
print "\nAfter replacing all the 'None' with ' ':"
print result.get_text()
Result:
结果：
The result of soup.find:
<span class="myclass">Lorem ipsum<br/>dolor sit amet,<br/>consectetur...</span>
result.contents:
[u'Lorem ipsum', <br/>, u'dolor sit amet,', <br/>, u'consectetur...']
result.get_text():
Lorem ipsumdolor sit amet,consectetur...
After replacing all the 'None' with ' ':
Lorem ipsum dolor sit amet, consectetur...
This is more elaborate than Sean's very compact solution - but since I had said I would create and test a solution along the lines I had indicate when I could, I decided to follow through on my promise. You can see a little better what is going on here - the <br/>is its own element in the result.contentstuple, but when converted to string there's "nothing left".
这比 Sean 的非常紧凑的解决方案更复杂 - 但既然我说过我会按照我指示的方式创建和测试一个解决方案，我决定兑现我的承诺。你可以更好地看到这里发生的事情 - 这<br/>是result.contents元组中它自己的元素，但是当转换为字符串时，“什么都没有”。

result.get_text(separator=" ")should work.
result.get_text(separator=" ")应该管用。
