Hi,

I have added a recipe for the HTML5 parsing library selectolax. I have tested it alongside a QML application by importing the package and parsing a HTML structure.

The compilation aswell as the import worked fine without any errors.

Here's the exact code that I used for testing:

import sys
import os
import traceback
import asyncio
from PySide6.QtCore import QObject, Slot, Signal
from PySide6.QtGui import QGuiApplication
from PySide6.QtQml import QQmlApplicationEngine

os.environ["QT_QUICK_CONTROLS_STYLE"] = "Material"
os.environ["QT_QUICK_CONTROLS_MATERIAL_THEME"] = "Dark"
os.environ["QT_QUICK_CONTROLS_MATERIAL_ACCENT"] = "Blue"

class ScraperBridge(QObject):
    titleExtracted = Signal(str)

    @Slot()
    def startParsing(self):
        asyncio.create_task(self.async_extract())

    async def async_extract(self):

        sample_html = """
        <html>
            <head><title>Test Page</title></head>
            <body>
                <div class="content">
                    <h1>Hello from Selectolax & PySide6 QML!</h1>
                    <p>This parsing engine is running blazingly fast in C.</p>
                </div>
            </body>
        </html>
        """

        # Parse using selectolax's Lexbor engine
        from selectolax.lexbor import LexborHTMLParser
        tree = LexborHTMLParser(sample_html)
        h1_node = tree.css_first("div.content h1")

        if h1_node:
            extracted_text = h1_node.text(strip=True)
        else:
            extracted_text = "H1 Element not found!"

        # Send the clean string back to the QML interface
        self.titleExtracted.emit(extracted_text)



async def main():
    app = QGuiApplication(sys.argv)
    engine = QQmlApplicationEngine()

   
    scraper_bridge = ScraperBridge()
    
    # Expose the Python object directly to the QML context engine
    engine.rootContext().setContextProperty("scraperBackend", scraper_bridge)

    engine.load("main.qml")

    if not engine.rootObjects():
        sys.exit(-1)

    while app.property("isExiting") is not True:
        app.processEvents()
        await asyncio.sleep(0.01)

if __name__ == "__main__":
    try:
        asyncio.run(main())
    except KeyboardInterrupt:
        pass

@EchterAlsFake Thanks for your contribution. Could you please shift recipe from CythonRecipe to PyProjectRecipe with appropriate cython version in hostpython perquisites?

@T-Dynamos Hi, I don't know which exact Cython version I am supposed to specify. I just left it without any version and it works just fine.

Am I supposed to just add the one permanently that works right now?
Pushed the new commit with PyProjectRecipe :)

@EchterAlsFake Thanks for changing.

As for cython version you can pin currently working version.
