用plotly/dash html组件替换一些文本周围的html标签

Answer 1

这是一个如何使用 beautifulsoup 将 HTML 解析为普通字典的示例。

然后您可以将字典转换为您需要的对象。

from bs4 import BeautifulSoup

html_text = """\
<tr>
        <td>
            <p>Item 1</p>
        </td>
        <td>
            <p>Definition for Item 1.</p>
            <p>This may contain several paragraphs.</p>
        </td>
</tr>
<tr>
        <td>
            <p>Item 2</p>
        </td>
        <td>
            <p>Definition for Item 2.</p>
            <p>This may contain several paragraphs.</p>
            <p>And another paragraph here.</p>
        </td>
</tr>"""

soup = BeautifulSoup(html_text, "html.parser")

out = {}
for row in soup.select("tr"):
    header, *definitions = row.select("td")
    header = header.get_text(strip=True)
    for p in definitions[0].select("p"):
        out.setdefault(header, []).append(p.get_text(strip=True))

print(out)

打印：

{
    "Item 1": ["Definition for Item 1.", "This may contain several paragraphs."],
    "Item 2": [
        "Definition for Item 2.",
        "This may contain several paragraphs.",
        "And another paragraph here.",
    ],
}
