const parsed = wxml.parse('<view></view>');
wxml.traverse(parsed, function visitor(node, parent) {
  const type = node.type;
  const parentNode = node.parentNode;

  if (type === wxml.NODE_TYPES.ELEMENT) {
    // handle element node
    const tagName = node.tagName;
    const attributes = node.attributes; // an object represents the attributes
    const childNodes = node.childNodes;
    const selfClosing = node.selfClosing; // if a node is self closing, like `<tag />`
  } else if (type === wxml.NODE_TYPES.TEXT) {
    // handle text node
    const textContent = node.textContent;
  } else if (type === wxml.NODE_TYPES.COMMENT) {
