Automatically convert html to dash format

Dash Python
1

Greetings.

In order to convert html to dash format more conveniently, I developed a Python library html-to-dash . You can use the command pip install html-to-dash to use it.

Here are some examples：

Basic usage

from html_to_dash import parse_html
element_str = """
<div>
    <div class='bg-gray-800' style='color:red;margin:10px'>
     <svg aria-label="Ripples. Logo" role="img" xmlns="http://www.w3.org/2000/svg"</svg>
        <a href="#" id="link1">A</a>
    </div>
    <div>text</div>
    <div><a href="#" id="link2">B</a></div>
</div>
"""
parse_html(element_str)

Print:

# Tags : Unsupported [svg] removed.
Result:
html.Div(
    children=[
        html.Div(
            className="bg-gray-800",
            style={"color": "red", "margin": "10px"},
            children=[html.A(href="#", id="link1", children=["A"])],
        ),
        html.Div(children=["text"]),
        html.Div(children=[html.A(href="#", id="link2", children=["B"])]),
    ]
)

Enable dash_svg

Use dash-svg module to render SVG tags.

from html_to_dash import parse_html

element_str = """
<svg xmlns=" http://www.w3.org/2000/svg " version="1.1" width="300" height="300">
  <rect x="100" y="100" width="100" height="100" fill="#e74c3c"></rect>
  <polygon points="100,100 200,100 150,50" fill="#c0392b"></polygon>
  <polygon points="200,100 200,200 250,150" fill="#f39c12"></polygon>
  <polygon points="100,100 150,50 150,150 100,200" fill="#f1c40f"></polygon>
  <polygon points="150,50 200,100 250,50 200,0" fill="#2ecc71"></polygon>
  <polygon points="100,200 150,150 200,200 150,250" fill="#3498db"></polygon>
</svg>
"""

parse_html(element_str, enable_dash_svg=True)

Print:

Result:
dash_svg.Svg(
    xmlns=" http://www.w3.org/2000/svg ",
    version="1.1",
    width="300",
    height="300",
    children=[
        dash_svg.Rect(x="100", y="100", width="100", height="100", fill="#e74c3c"),
        dash_svg.Polygon(points="100,100 200,100 150,50", fill="#c0392b"),
        dash_svg.Polygon(points="200,100 200,200 250,150", fill="#f39c12"),
        dash_svg.Polygon(points="100,100 150,50 150,150 100,200", fill="#f1c40f"),
        dash_svg.Polygon(points="150,50 200,100 250,50 200,0", fill="#2ecc71"),
        dash_svg.Polygon(points="100,200 150,150 200,200 150,250", fill="#3498db"),
    ],
)

In addition, it also supports advanced functions such as expanding modules and removing tags. More content can be found in the github repository：GitHub - PierXuY/html-to-dash: Convert HTML to dash format.

I hope it can be helpful to you.
