Fenced code blocks with multiple children (spans from highligters) not converted about html2md HOT 3 CLOSED

Hi sanzoghenzo, I don't think that's a standard for code blocks.

In the custom rule, you can get the parents or maybe any elements you want, by using the dom api.
For example(may not work): node.asElement()?.parent?.parent?.classes;

from html2md.

Thanks @jarontai, your example missed a parent, but it was very helpful!

I've turned it into a generic "walker" of all the parents, I'll leave it here for posterity:

String getLanguage(node) {
  var regex = RegExp(r'language-(\S+)');
  var className = node.firstChild!.className;
  var languageMatched = regex.firstMatch(className)?.group(1);
  if (languageMatched != null) {
    return languageMatched;
  }
  var nodeElement = node.asElement();
  while (nodeElement.parent != null) {
    nodeElement = nodeElement.parent;
    for (var className in nodeElement.classes) {
      languageMatched = regex.firstMatch(className)?.group(1);
      if (languageMatched != null) {
        return languageMatched;
      }
    }
  }
  return '';
}

from html2md.

I tried with a custom rule, and replacing the incriminated line with childNodes().map((e) => e.textContent).join() renders all the code.

I'm not sure how to solve the language identification, that info appears two divs up instead of in the first children. I don't know if it a standard of some kind or a particular case of this website (it uses jekyll and a bootstrap theme).
