Answer 1

Easy to do with Selenium:

driver.get('http://lenta.ru')
driver.execute_script('''
var aTags = document.getElementsByTagName("a");
for (var i = 0; i < aTags.length; i++) {
  if (aTags[i].innerText.startsWith("07:50Опубликованы данные")) {
    aTags[i].innerText = "Утки с Марса захватили вселенную!";
    break;
  }
}
''')
time.sleep(1)

screenshot = driver.get_screenshot_as_png()

I took a more complicated example. In your case, for sure, the selector can be chosen simpler

You use some framework so that you can add a browser host to the window. For example Qt.
You load the page into the browser and change it, either by accessing the DOM or by executing scripts. QtWebEngine allows this. Then you take a picture.
