添加父标签与美丽的汤 [英] Add parent tags with beautiful soup
问题描述
我有包含这些code片段各个部分的HTML多页：
I have many pages of HTML with various sections containing these code snippets:
<div class="footnote" id="footnote-1">
<h3>Reference:</h3>
<table cellpadding="0" cellspacing="0" class="floater" style="margin-bottom:0;" width="100%">
<tr>
<td valign="top" width="20px">
<a href="javascript:void(0);" onclick='javascript:toggleFootnote("footnote-1");' title="click to hide this reference">1.</a>
</td>
<td>
<p> blah </p>
</td>
</tr>
</table>
</div>
我可以成功地解析HTML和提取这些相关的标签
I can parse the HTML successfully and extract these relevant tags
tags = soup.find_all(attrs={"footnote"})
现在我需要添加这些这些新的父标签的code段云：
Now I need to add new parent tags about these such that the code snippet goes:
<div class="footnote-out"><CODE></div>
但我找不到添加父标签BS4这样，他们振奋的识别标签的方法。插入（）/ insert_before识别的标记之后加入
But I can't find a way of adding parent tags in bs4 such that they brace the identified tags. insert()/insert_before add in after the identified tags.
我开始试图通过字符串manupulation：
I started by trying string manupulation:
for tags in soup.find_all(attrs={"footnote"}):
tags = BeautifulSoup("""<div class="footnote-out">"""+str(tags)+("</div>"))
但我相信这不是最好的办法。
but I believe this isn't the best course.
感谢您的帮助。只是用BS / BS4开始，但似乎无法破解这个。
Thanks for any help. Just started using bs/bs4 but can't seem to crack this.
推荐答案
这个怎么样：
def wrap(to_wrap, wrap_in):
contents = to_wrap.replace_with(wrap_in)
wrap_in.append(contents)
简单的例子：
from bs4 import BeautifulSoup
soup = BeautifulSoup("<body><a>Some text</a></body>")
wrap(soup.a, soup.new_tag("b"))
print soup.body
# <body><b><a>Some text</a></b></body>
与文档示例：
for footnote in soup.find_all("div", "footnote"):
new_tag = soup.new_tag("div")
new_tag['class'] = 'footnote-out'
wrap(footnote, new_tag)
