var callback = function (response) {

        console.log(responseMessage)

    var parseHandler = function () {

        var temp2 = this.resultDoc.currentConditions.ports[0].port[1].condition[0].currentReading[0]
        var temp3 = this.resultDoc.currentConditions.ports[0].port[2].condition[0].currentReading[0]
        var temp4 = this.resultDoc.currentConditions.ports[0].port[3].condition[0].currentReading[0]
        var humidity = this.resultDoc.currentConditions.ports[0].port[1].condition[1].currentReading[0]
                var data  = {TEMP1:temp1,TEMP2:temp2,TEMP3:temp3,TEMP4:temp4,HUMIDITY:humidity};

        return data;
    };
};
http.request(options, callback).end();
var builder = new xml2js.Builder();
//console.log('Is the temp array below????');
console.log(callback.parseHandler);
//console.log('----------------');
//var xml = builder.buildObject(data);
//console.log(xml);

上下文：我正在尝试从服务器读取xml数据，从我想要的元素中提取数据，然后编写一个新的xml。我已经独立地想出了这些过程，但是当我尝试传递我的数据时＃39;对象我的xmlbuilder就像它没有收到的那样。我尝试了几种不同的方法来尝试引用我的数据＆＃39;对象，我无法弄清楚如何在parseHandler类之外完成它。我是JS的新手（很明显）？此时我只想弄清楚如何访问我的数据对象内容。提前谢谢....

试图访问函数内部的对象，构建xml
