使用 BeautifulSoup 仅打印 HTML 代码中的外部标签 [英] Printing only outer tags in HTML code using BeautifulSoup

问题描述

部分 HTML 代码如下

<a class="reserve" data-target="#myModal" data-toggle="modal"href="example.com" rel="nofollow"></a></td>

我发现它使用

soup.find_all('td', class_='col2')

但是我不想提取代码的全部部分，而只想提取

可以使用 BeautifulSoup 吗?我知道我可以使用字符串来完成，但我只是好奇.

解决方案

您可以将 string 属性设置为空字符串 (''):

html = """;<td class="col2"><a class="reserve";数据目标=#myModal"；数据切换=模态"href=example.com"rel=nofollow"></a></td>"汤 = BeautifulSoup(html)x = 汤.find('td', class_='col2')x.string = ''打印(x)

输出

<td class="col2"></td>

以下是文档 的说明:

<块引用>

如果你设置了标签的 .string 属性，标签的内容将被你提供的字符串替换

<块引用>

注意:如果标签包含其他标签，它们及其所有内容都将被销毁.

Part of whole HTML code looks as follows

<td class="col2">
<a class="reserve" data-target="#myModal" data-toggle="modal"     
href="example.com" rel="nofollow"></a></td>

I found it using

soup.find_all('td', class_='col2')

However I would like to extract not the whole part of the code but only

<td class="col2"></td>

Is it possible using BeautifulSoup? I know I can do it using strings but I'm just curious.

解决方案

You could set the string attribute to an empty string (''):

html = """
<td class="col2">
<a class="reserve" data-target="#myModal" data-toggle="modal"     
href="example.com" rel="nofollow"></a></td>
"""
soup = BeautifulSoup(html)
x = soup.find('td', class_='col2')
x.string = ''
print(x)

Output

<td class="col2"></td>

Here is what documentation tells about it:

If you set a tag's .string attribute, the tag's contents are replaced with the string you give

Be careful: if the tag contained other tags, they and all their contents will be destroyed.
