核心代码

var partialxhtml = function (value) {
  return value.replace(/<(\/?[a-za-z]+\s*)((?:"[^"]*"|'[^']*'|(?!'|"|\/?>).)*)(\/?>)/g, function (l, $1, $2, $3) {
    return '<' + $1.tolowercase() + $2.replace(/([^=]+)=(?:(")[^"]*"|(')[^']*'|((?:(?!\s|'|"|\/?>).)*))/g, function (l, $1, $2, $3, $4) {
      return ($2||$3) ? l : $1 + '="' + $4 + '"';
    }) + $3;
  });
};
