How to use the prosemirror-model.DOMParser function in prosemirror-model

var width = dom.getAttribute("width");
  if (width) {
    return width;
  }
  return undefined;
};

// Needs to lift out image blocks in their own div
var transformPastedHTML = function transformPastedHTML(htmlStr) {
  var markdown = (0, _markdownToHTML.markdowntoHTML)(htmlStr);
  return markdown;
  return htmlStr;
};

var clipboardParser = new _prosemirrorModel.DOMParser(_schema.schema, defaultRules);

exports.transformPastedHTML = transformPastedHTML;
exports.clipboardSerializer = clipboardSerializer;
exports.clipboardParser = clipboardParser;

};

  nodeSerializer.embed = function toDOM(node) {
    return null;
  };

  const clipboardSerializer = new DOMSerializer(nodeSerializer, markSerializer);
  const defaultRules = DOMParser.schemaRules(schema);
  const transformPastedHTML = function(htmlStr) {
    return htmlStr;
    // const markdown = markdowntoHTML(htmlStr);
    // return markdown;
  }

  const clipboardParser = new DOMParser(schema, defaultRules);
