    我用BeautifulSoup来提取一个网站,得到了一个需要的文本。问题是文本中有“\n”字符,需要删除。在

    输出文本示例:\nI went to an advance screening of this movie thinking I was about

    to\nembark on 120 minutes of cheezy lines, mindless plot, and the kind

    of\nnauseous acting that made "The Postman" one of the most

    malignant\ndisplays of cinematic blundering of our time. But I was

    shocked.\nShocked to find a film starring Costner that appealed to the

    soul of\nthe audience. Shocked that Ashton Kutcher could act in such a

    serious\nrole. Shocked that a film starring both actually engaged and

    captured\nmy own emotions. Not since 'Robin Hood' have I seen this

    Costner: full\nof depth and complex emotion. Kutcher seems to have

    tweaked the serious\nacting he played with in "Butterfly Effect".

    These two actors came into\nthis film with a serious, focused attitude

    that shone through in what I\nthought was one of the best films I've

    seen this year. No, its not an\nOscar worthy movie. It's not an epic,

    or a profound social commentary\nfilm. Rather, its a story about a

    simple topic, illuminated in a way\nthat brings that audience to a

    higher level of empathy than thought\npossible. That's what I think

    good film-making is and I for one am\nthroughly impressed by this

    work. Bravo!\n

    我尝试了以下方法来删除新行。在

    方法1-正则表达式x = review_text.get_text()

    y = re.sub(r'(\n)','',x)

    方法2-rstrip

    ^{pr2}$

    这两种方法都不适合我。在

    当我使用分割时x = review_text.get_text()

    print(x.split("\n"),"\n\n")

    输出如下['\nI went to an advance screening of this movie thinking I was about

    to\nembark on 120 minutes of cheezy lines, mindless plot, and the

    kind of\nnauseous acting that made "The Postman" one of the most

    我该怎么做才能从文本中删除新行。在

    删除字符串中换行符 c++

    How to remove newline characters from a string in C++?

    如何从C ++中的字符串中删除换行符?

    For example, a string like

    例如,像这样的字符串

    line 1
    
    line 3
    line 4

    should be converted to

    应该转换为

    line 1line 3line 4

    方法1:使用`erase()`和`remove()` (Method 1: use `erase()` and `remove()`)

    In short, use this code snippet:

    简而言之,请使用以下代码段:

    input.erase(std::remove(input.begin(), input.end(), '\n'),
                input.end());

    std::remove() shifts all elements that are equal to the value \n by moving the elements in the range to the end and returns the past-the-end iterator for the new range of values that are not \n.

    std::remove()通过将范围中的元素移到末尾来移动所有等于值\n的元素,并为非\n的新值范围返回过去的迭代器。

    std::erase() removes elements from the container in the range specified and updates the size of the vector.

    std::erase()在指定范围内从容器中删除元素,并更新向量的大小。

    For the above piece of code, the range of elements removed are all \ns.

    对于上面的代码,删除的元素范围都是\n s。

    A full example program,

    完整的示例程序

    #include <iostream>
    #include <algorithm>
    
    int main ()
    {
      std::string input{"line 1\n\n\nline 3\nline 4"};
    
      std::cout << "input:\n" << input << "\n";
    
      input.erase(std::remove(input.begin(), input.end(), '\n'), input.end());
    
      std::cout << "After:\n" << input << "\n";
    
      return 0;
    }
    

    Execution outputs:

    执行输出:

    input:
    line 1
    
    line 3
    line 4
    After:
    line 1line 3line 4

    方法2:使用`regex_replace()` (Method 2: use `regex_replace()`)

    Use a regular expression to match consequence \ns and replace the matched strings with "" (empty string).

    使用正则表达式匹配结果\n然后将匹配的字符串替换为"" (空字符串)。

    #include <iostream>
    #include <algorithm>
    #include <regex>
    
    int main ()
    {
      std::string input{"line 1\n\n\nline 3\nline 4"};
    
      std::cout << "input:\n" << input << "\n";
    
      std::regex newlines_re("\n+");
    
      auto result = std::regex_replace(input, newlines_re, "");
    
      std::cout << "After:\n" << result << "\n";
    
      return 0;
    }

    Execution results:

    执行结果:

    input:
    line 1
    
    line 3
    line 4
    After:
    line 1line 3line 4
