如何在SAP Netweaver网关HTTP适配器中使用响应？

I'm integrating SAP and IBM MobileFirst using SAP Netweaver Gateway HTTP Adapter. I am able to connect to the SAP Backend System successfully and I'm getting the data in a xml format. This is the response I'm getting:

我正在使用SAP Netweaver Gateway HTTP Adapter集成SAP和IBM MobileFirst。我能够成功连接到SAP后端系统,并且我以xml格式获取数据。这是我得到的回应:

Now I want to pick a particular value from the xml. Can any one help me out in this area?

现在我想从xml中选择一个特定的值。任何人都能在这方面帮助我吗?

function retrieveTravelAgencyProperty() {
var request = {
    CollectionName: "SampleUserProcessing",

};
return WL.Server.fetchNWBusinessObject(request);
}

So back in your client logic, in the success callback of the adapter invocation you get a JSON object. This JSON object contains the response.

所以回到你的客户端逻辑中,在适配器调用的成功回调中,你得到一个JSON对象。此JSON对象包含响应。

So what I'm thinking you should do is to:

所以我在想你应该做的是:

Either extract to another variable, or work directly on, the "RETURN" key from the response and

要么提取到另一个变量,要么直接在响应中使用“RETURN”键

Make it into a readable JSON format again, something like this: http://davidwalsh.name/convert-xml-json

再次将它变成可读的JSON格式,如下所示:http://davidwalsh.name/convert-xml-json

Iterate over the refreshed respone to find the key:value you're looking for. For example:

迭代刷新的respone来找到关键:你正在寻找的价值。例如:

for (i = 0; i < resultSet.length; i++) {
    if (resultSet[i].name == "some-value") { // assumed that you know what you're lookign for.
        alert (resultSet[i].name);
}

Step 2 is the difficult part... not sure about it.

第2步是困难的部分......不确定。
