BeautifulSoup:将所有p个元素合并到一个字符串中吗?

我目前使用以下Python代码摘录来获取网页的所有

元素:

def scraping(url, html):
    data = {}
    soup = BeautifulSoup(html,"lxml")

    data["news"] = []

    page = soup.find("div", {"class":"container_news"}).findAll('p')
    page_text = ''

    for p in page:
        page_text += ''.join(p.findAll(text = True))
        data["news"].append(page_text)
    print(page_text)

    return data

但是,page_text的输出如下:

"['New news on the internet. ', 'Here is some text. ', ""Here is some other."", ""And then there are other variations \n\nLooks like there are some non-text elements. \n\xa0""]" ...

是否可以使内容清理程序并将列表合并为一个字符串?相较于regex变体,BeautifulSoup解决方案将是首选。

谢谢!

我不确定维护data["news"]的重要性,但这可以在一行中完成:

page_text = ' '.join(e.text for p in page for e in p.findAll(text=True))

您可以使用所需的任何字符串代替定界符来代替' '

否则

page_text = []

for p in page:
    page_text.extend(e.text for e in p.findAll(text=True))
    data["news"].append(page_text)

print(' '.join(page_text))
