使用XSLT将xml平面转换为分层XML转换

Question

我正在尝试创建一个将平面结构（带有父/子id）映射到层次结构的转换。我在下面列出了一个简单的请求和响应示例。实际数据有500多个元素。任何帮助将非常感激！谢谢！

验证规则：

1. 优惠可以在顶级
2. 优惠可以打包
3. 优惠可以在
下

请求：

Answer 1

这是一个使用keys的XSLT 1.0解决方案。

样式表声明了四个用于查找不同对象的键：

1. 顶级对象的类型（包或商品），
2. 按包ID分组
3. 根据包ID和
提供属于包的内容
4. 按群组ID提供属于某个群组。

在顶层，样式表处理顶级商品和包。在包级别，样式表处理属于该包的组和商品。在组级别，系统处理属于该组的商品。

app.directive('sideNav', function() {
return{
    restrict: 'E',
    templateUrl: 'side_nav.html',
    link: function(scope, element, attrs){
       // execute metisMenu plugin
        setTimeout(function(){
            $(element).metisMenu();
        }, 1);
    },
    controller: function(){
        this.selectedNav = {};

        this.selectTab = function(setTab){
            this.tab = setTab;
        };
        this.isSelected = function(checkTab){
            return checkTab === this.tab;
        };

        this.navItems = [{
            name: 'Dashboard',
            icon: 'fa-dashboard'
        },{
            name: 'Logs',
            icon: 'fa-code'
        },{
            name: 'Firm Diagnostics',
            icon: 'fa-stethoscope',
            navItems: [
                {
                    name: 'Disk I/O'
                },{
                    name: 'Disk Space'
                },{

                },{
                    name: 'Processor Activity'

                },{
                    name: 'Memory Usage'
                },{
