BeautifulSoup4：与符号文本 [英] BeautifulSoup4 : Ampersand in text

问题描述

我在使用BeautifulSoup4一个问题...（我相当一个Python / BeautifulSoup新手，所以请原谅我，如果我哑）

I have a problem using BeautifulSoup4... (I'm quite a Python/BeautifulSoup newbie, so forgive me if i'm dumb)

为什么以下code：

from bs4 import BeautifulSoup

soup_ko = BeautifulSoup('<select><option>foo</option><option>bar & baz</option><option>qux</option></select>')
soup_ok = BeautifulSoup('<select><option>foo</option><option>bar and baz</option><option>qux</option></select>')

print soup_ko.find_all('option')
print soup_ok.find_all('option')

产生下面的输出：

produce the following output:

[<option>foo</option>, <option>bar &amp; baz</option>]
[<option>foo</option>, <option>bar and baz</option>, <option>qux</option>]

我期待相同的结果，我的3个选项的数组...但BeautifulSoup似乎不喜欢在文字与符号？我怎样才能摆脱这种并得到一个正确的阵列，而无需编辑我的HTML（或通过变换/转换的话）？

i was expecting the same result, an array of my 3 options... but BeautifulSoup seems to dislike the ampersand in the text? How can i get rid of this and get a correct array without editing my HTML (or by transforming/converting it)?

感谢，

编辑：似乎是一个错误4.2.0 ...我下载都和4.2.0版本4.2.1（从的http://www.crummy.com/software/BeautifulSoup/bs4/download/4.2/beautifulsoup4-4.2.0.tar.gz和的http://www.crummy.com/software/BeautifulSoup/bs4/download/4.2/beautifulsoup4-4.2.1.tar.gz),将它解压缩在我的脚本文件夹，更改我的code为：

Seems like a 4.2.0 bug... i downloaded both 4.2.0 and 4.2.1 versions (from http://www.crummy.com/software/BeautifulSoup/bs4/download/4.2/beautifulsoup4-4.2.0.tar.gz and http://www.crummy.com/software/BeautifulSoup/bs4/download/4.2/beautifulsoup4-4.2.1.tar.gz), unzip it in my script folder, change my code to:

import sys
sys.path.insert(0, "beautifulsoup4-" + sys.argv[1])
from bs4 import BeautifulSoup, __version__

print "Beautiful Soup %s" % __version__
soup_ko = BeautifulSoup('<select><option>foo</option><option>bar & baz</option><option>qux</option></select>')
print soup_ko.find_all('option')

和得到的结果：

15:24:38 pataluc ~ % python stack.py 4.2.0
Beautiful Soup 4.2.0
[<option>foo</option>, <option>bar &amp; baz</option>]
15:24:41 pataluc ~ % python stack.py 4.2.1
Beautiful Soup 4.2.1
[<option>foo</option>, <option>bar &amp; baz</option>, <option>qux</option>]

所以我想我的问题是关闭的。感谢您的意见谁使我意识到这是一个版本的问题。

so i guess my question is closed. thanks for your comments who made me realize it was a version issue.

推荐答案

正如我在编辑的第一篇文章说，这是BeautifulSoup 4.2.0中的错误，我下载4.2.1和错误也没有了。

As i said in the edited first post, it was a bug in BeautifulSoup 4.2.0, i downloaded 4.2.1 and the bug is gone.
