[LayaAirIDE 2.0]用2.1.1版本IDE发布oppo小游戏，domparserinone报错

正好刚遇到这个问题，exports的两段改一下写法兼容一下就好了
 
if (typeof exports === 'object' && typeof module === 'object')
    module.exports = XMLReader;
else if (typeof define === 'function' && define['amd'])
    define([], function () { return XMLReader; });
else if (typeof exports === 'object')
    exports["XMLReader"] = XMLReader;
 
 
if (typeof exports === 'object' && typeof module === 'object') {
    module.exports = DOMImplementation;
    module.exports = XMLSerializer;
}else if (typeof define === 'function' && define['amd']) {
    define([], function () { return DOMImplementation; });
    define([], function () { return XMLSerializer; });
}else if (typeof exports === 'object') {
    exports["DOMImplementation"] = DOMImplementation;
    exports["DOMImplementation"] = XMLSerializer; 
}
