我正在使用这种 XML 格式，如何使用 Titanium 从中获取国家/地区的名称？

在寻求帮助之前，至少尝试解析 XML or at least show you know where the DOCS are 是一种善意的姿态。但幸运的是，这对于 Titanium 来说非常简单，这里有一个例子：

// Load file containing XML from resources directory
var xmlFile = Ti.Filesystem.getFile('countries.xml');

// Get contents(as blob) from file
var contents = xmlFile.read();

// Turn contents into a XMLDomDocument for parsing (get string from blob first)
var xmlDomDoc = Ti.XML.parseString(contents.text);

// Get all the item tags and their contents
var allItemTags = xmlDomDoc.getElementsByTagName('item');

// Loop over them and grab the text contents and print
for (var i = 0; i < allItemTags.length; i++) {
    var countryName = allItemTags.item(i).textContent;
    Ti.API.info(countryName);
}

粗略检查一下我提供的链接会向您展示如何执行此操作的 API。

上面的xml响应是动态的，我自己解析了下面的xml就是解决办法

Ti.API.info('Original response ' + this.responseText);

// Document Object
var doc = this.responseXML.documentElement;

Ti.API.info('Document XML' + doc);

var elements = doc.getElementsByTagName("item");

Ti.API.info('Document item' + elements.text);

//this is the XML document object

// Parse XML
var xml = Ti.XML.parseString(this.responseText);
Ti.API.info('Parsed XML' + xml);

// get item from xml
var countryList = xml.documentElement.getElementsByTagName("item");

Titanium.API.info("country is " + countryList);
Titanium.API.info("lenght of countries" + countryList.length);
Titanium.API.info("country is " + countryList.item(0));

for (var i = 0; i < countryList.length; i++) {
    Titanium.API.info("loop country is " + countryList.item(i).text);
    countryArray[i] = countryList.item(i).text;
};

Titanium.API.info("Array country is " + countryArray);

var win = Titanium.UI.createWindow({  
    title:"XHR",
    backgroundColor:"#FFFFFF",
    exitOnClose:true
});

var data = [];//We'll fill this table after the xml has loaded
var tableView = Titanium.UI.createTableView({
    data:data
});

function errorMessage(){
    alert("Well, that didn't work");
}

function renderXML(){
    var tours = this.responseXML.documentElement;
    var tour = tours.getElementsByTagName("tour");

    //traverse the tour node, pull out the titles
    for(var i=0; i<tour.length;i++){
        var item = tour.item(i);
        var title = item.getElementsByTagName("tourTitle").item(0).text;

        var row = Titanium.UI.createTableViewRow({
            title:title,
            className:"tableRow",
        });
        data.push(row);
    }

    tableView.setData(data);

}

var xhr = Titanium.Network.createHTTPClient({
    onload: renderXML,
    onerror: errorMessage
});

win.add(tableView);

xhr.open("GET","http://services.explorecalifornia.org/rest/tours.php");
xhr.send();

win.open();
