我正在尝试创建一个桌面应用程序，它将加载 iTunes 播放列表 xml 文件并使用 Haxe 和框架 haxenme 解析它。

我认为我遇到的问题可能是文件名中的空格没有被正确转义，但我对此不是 100% 确定的。

这是我到目前为止的代码。

package com.mattwallace.appname.actions;

    import nme.Assets;
    import haxe.xml.Fast;

    class GetPlayListAction 
    {
        public function new():Void
        {
            super();
        }

        public function execute():Void
        {

            var xml:Xml = Xml.parse(getXMLDesktopString());
            trace(xml);
        }

        private function getXMLDesktopString():String
        {

            var xmlString:String = sys.io.File.getContent(
                nme.filesystem.File.userDirectory.url + 
                "/Music/iTunes/iTunes Music Library.xml");
            return xmlString;
        }
    }

好吧，好像我一发帖就总能找到答案。问题是“File.userDirectory.url”我需要使用“File.userDirectory.nativePath”

这是为我解决问题的更新代码。

class GetPlayListAction
{
    public function new():Void
    {
    }

    public function execute():Void
    {

        var xml:Xml = Xml.parse(getXMLDesktopString());
        trace(xml);
    }

    private function getXMLDesktopString():String
    {
        var nativeUserDir:String = nme.filesystem.File.userDirectory.nativePath;
        var filePath:String = "/Music/iTunes/iTunes Music Library.xml";
        var fullPath = nativeUserDir + filePath;

        var xmlString:String = sys.io.File.getContent(fullPath);
        return xmlString;
    }
}
