python - beautifulsoup - removing a line of code












3















I started to learn the beautifulsoup. I am trying to remove from html script a line of code containing </div> .



The most examples in the documentation are presented for the whole tags (opening and closing part).


Is it possible to modify just one part of a tag?
For example:



</div>
<div >Hello</div>
<div data-foo="value">foo!</div>



how to remove just the first line of the code?

          You can use BeautifulSoup's unwrap() to specify the invalid tag, which will only remove the extra tags that don't have a open/close counterpart, while retaining others:



          soup = BeautifulSoup(html_doc, 'html.parser')

          invalid_tags = ['</div>']

          for tag in invalid_tags:
          for match in soup.findAll(tag):
          match.unwrap()

          print(soup)


          result:



          <div>Hello</div>
          <div data-foo="value">foo!</div>

          • Shouldn't invalid_tags = ['<div>'] be ['</div>']?

          you don't need do anything it will repaired automatically



          from bs4 import BeautifulSoup

          html_doc = '''</div>
          <div>World</div>
          <div data-foo="value">foo!''' # also invalid, no closing

          soup = BeautifulSoup(html_doc, 'html.parser')
          print(soup)


          output



          <div>World</div>
          <div data-foo="value">foo!</div>


          unwrap() is for removing not repairing tag.
