提取HTML页面中的所有<script>标记并附加到文档的底部

Mri*_*lla 1 python beautifulsoup

有人可以告诉我如何提取和删除<script>HTML文档中的所有标记,并将它们添加到文档的末尾,就在之前</body></html>?我想尽量避免使用lxml.

谢谢.

答案很简单,可能会遗漏许多细微差别.但是,这应该让你知道如何去做,一般来说改进它.我相信这可以改进,但你应该能够在文档的帮助下快速完成.

from bs4 import BeautifulSoup

doc = ['<html><script type="text/javascript">document.write("Hello World!")',
       '</script><head><title>Page title</title></head>',
       '<body><p id="firstpara" align="center">This is paragraph <b>one</b>.',
       '<p id="secondpara" align="blah">This is paragraph <b>two</b>.',
       '</html>']
soup = BeautifulSoup(''.join(doc))


for tag in soup.findAll('script'):
    # Use extract to remove the tag
    tag.extract()
    # use simple insert
    soup.body.insert(len(soup.body.contents), tag)

print soup.prettify()
