Could someone tell me how I can extract and remove all the <script> tags in a HTML document and add them to the end of the document, right before开发者_如何学JAVA the </body></html>? I'd like to try and avoid using lxml please.

Thanks.

The answer is simple and may miss many nuances. How ever, this should give you an idea of how to go about doing it, improving it in general. I am sure this can be improved but you should be able to do that quickly with help of the documentation.

Reference doc: http://www.crummy.com/software/BeautifulSoup/documentation.html

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()

Output:

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