问题是，当我抓取数据时，它全部压缩成一个长字符串，没有任何空格或回车。我怎样才能解决这个问题？我正在使用此代码从表格中提取文本：

mech = Browser()
page = mech.open(BASE_URL_DIRECTORY)
html = page.read()
soup = BeautifulSoup(html)
data = extract(soup)

def extract(soup):
    table = soup.find("table",attrs={'id':'ctl00_TemplateBody_WebPartManager1_gwpste_container_SearchForm_ciSearchForm_RTable'})
    #print table
        data = []
    for row in table.findAll("tr"):
        s = row.getText()
        data.append(s)
    return data

Answer 1

您可以使用replace_with() 将每个br 标记替换为换行符：

def extract(soup):
    table = soup.find("table", attrs={'id':'ctl00_TemplateBody_WebPartManager1_gwpste_container_SearchForm_ciSearchForm_RTable'})
    for br in table.find_all('br'):
        br.replace_with('\n')
    return table.get_text().strip()

对于您提供的 HTML 输入，它会打印：
