在列表中从BeautifulSoup输出拆分字符串 [英] Split string from BeautifulSoup output in a list

问题描述

我的代码有以下输出

代码: text = soup.get_text()

输出:

Article Title

    Some text: Text blurb.

More blurb.

Even more blurb. 

Some more blurb. 





Second Article Title

Some text: Text blurb.

More blurb.

Even more blurb. 

Some more blurb. 

接下来，当我执行 test = text.splitlines()时，输出更改为

Next, when I do test = text.splitlines(), the output changes to

u'Article Title', u'', u'Some text',u'Text blurb',u'More blurb',u'Even more blurb',u'Some more blurb',, u'', u'', u'', u'', u'',u'Second Article Title', u'', u'Some text:',u'Text blurb',u'More blurb',u'Even more blurb',u'Some more blurb',, u'', u'', u'', u'', u'',

我想用 u''，u''，u''，u''，u''分割字符串，以便随后分别解析各行.我本来想使用标签，但是它们的结构使它难以使用.

I'd like to split the string using u'', u'', u'', u'', u'' so that I can then individually parse out the lines. I'd have liked to use the tags but their structure makes it difficult to use.

如何执行拆分?我已经尝试过:

How do I perform the split? I have tried:

result = [list(g) for k,g in groupby(test,lambda x:x=="u''") if not k]
print result

和

for item in test:
    arr = re.split("u'', u'', u'', u'', u''",item, flags=re.UNICODE)
    print arr

但是他们没有给我想要的输出.

but they don't give me the desired output.

推荐答案

如果您查看文字，则希望通过重复的换行符 \ n 从

If you take a look at your text, you want to split by repeated newlines \n from

text
>> 'Article Title\n\n    Some text: Text blurb.\n\nMore blurb.\n\nEven more blurb. \n\nSome more blurb. \n\n\n\n\n\nSecond Article Title\n\nSome text: Text blurb.\n\nMore blurb.\n\nEven more blurb. \n\nSome more blurb. '

然后，您可以仅使用 text.split('\ n \ n \ n \ n \ n')的定义参数，如果不添加参数，Python会简单地按空格.第一次拆分后，您可以按 \ n \ n 拆分其他元素.

You can then just use define a parameter for text.split('\n\n\n\n\n'), if you don't add a parameter, Python simply splits by whitespaces. After your first split, you can then split your other elements by \n\n.

[i.split('\n\n') for i in text.split('\n\n\n\n\n')]

>>[['Article Title',
  '    Some text: Text blurb.',
  'More blurb.',
  'Even more blurb. ',
  'Some more blurb. '],
 ['\nSecond Article Title',
  'Some text: Text blurb.',
  'More blurb.',
  'Even more blurb. ',
  'Some more blurb. ']]
