如何使用BeautifulSoup从这个切分中获取文本？

Question

我需要使用bs4获取文本‘请再次登录’

<div id="msgDiv" align="left" class="msgdiv">
<font class="errorfont">
    <xmp style="white-space: normal;margin:0px;font-family:tahoma,arial,san-serif;">Please login again.</xmp>
</font>

​

我试过了，但什么也没得到：

page.select('#msgDiv > font > xmp')

Answer 1

也许这会有帮助

from bs4 import BeautifulSoup

text = """
<div id="msgDiv" align="left" class="msgdiv">
<font class="errorfont">
    <xmp style="white-space: normal;margin:0px;font-family:tahoma,arial,san-serif;">Please login again.</xmp>
</font>
"""

soup = BeautifulSoup(text, 'html.parser')
tag = soup.select('div#msgDiv > font.errorfont > xmp')[0]
print(tag.get_text())

Answer 2

它可以很好地使用来自bs4导入BeautifulSoup的以下代码

text = """
     <div id="msgDiv" align="left" class="msgdiv">
        <font class="errorfont">
           <xmp style="white-space: normal;margin:0px;font-family:tahoma,arial,san-serif;">Please login again.</xmp>
        </font>
    </div>
      """

   soup = BeautifulSoup(text, "html.parser")
   print(soup.xmp.text)

Answer 3

这应该能起到作用：

from bs4 import BeautifulSoup

text = """
<div id="msgDiv" align="left" class="msgdiv">
<font class="errorfont">
    <xmp style="white-space: normal;margin:0px;font-family:tahoma,arial,san-serif;">Please login again.</xmp>
</font>
"""

soup = BeautifulSoup(text, 'html.parser')
for tag in soup.find_all('div', attrs = {'class': 'msgdiv'}):
    for xmp in tag.find_all('font'):
        print(xmp.text)
