我正在使用 Flash Builder 4.6 制作一个 Flex 移动应用程序，我对想要实现的功能有疑问。

我有一个声明：

<s:HTTPService id="getXMLFile" fault="trace('No CCR found!')" result="getPatient(event)"
                       resultFormat="object" url="assets/CCR1.xml"/>

但这仅指向一个文件，并且必须输入。现在已经如何更改 url 并再次执行请求。

getXMLFile.url = "assets/CCR2.xml";
getXMLFile.send();

但我希望有某种功能来检查“资产”包中的所有文件以及每个文件的此代码部分。所以我想要这样的东西：

for(var file:string in assets) {
getXMLFile.url = "assets/" + file;
getXMLFile.send();
}

谢谢

        //Create one xml having all URL, which you can parse on Flex side. Collect all URL in Array (ex:- fileArray),

        private var count:int = 0;

        //Collect all URL in this fileArray.
        private function parseXML():void
        {
            //parse XML and puch URL in fileArray
            // xmlLength var is xml length.
            var xmlLength:int;
            for(var i:int;i<xmlLength ;i++)

    <s:HTTPService id="getXMLFile" fault="faultHandler(event)" result="getPatient(event)" resultFormat="object" />

这可能会帮助你......
