合并具有相似父节点，xml，nodejs的子节点

Question

我正在使用xml2js在builder方法的帮助下将js对象转换为xml。 js对象：

let rules={
            objects : [
                {
                    object: {
                        $: {
                            id: '1'
                        },
                        parameters: [
                            {
                                parameter:{
                                    ob_name: 'aaaaa',
                                    selector : 'in',
                                    value : '50',
                                }
                            },
                            {
                                joiner : 'or',
                                additionalParameters:{
                                    ob_name: 'bbbb',
                                    selector: 'out',
                                    value: '30',
                                },
                            },
                            {
                                joiner : 'and',
                                additionalParameters:{
                                    ob_name: 'cccc',
                                    selector: 'in',
                                    value: '20',
                                },
                            }
                        ],
                        actions: {
                            action: {
                                activity:'call',
                                operation:{
                                    name:'random',
                                    id:'304234',
                                    number:'0721333422'
                                },
                                period:'6'
                            }
                        },
                    }
                },
                {
                    object: {
                        $: {
                            id: '2'
                        },
                        parameters: [
                            {
                                parameter:{
                                    ob_name: 'ddddd',
                                    selector : 'in',
                                    value : '40',
                                }
                            },
                            {
                                joiner : 'or',
                                additionalParameters:{
                                    ob_name: 'eeeee',
                                    selector: 'in',
                                    value: '30',
                                },
                            },
                        ],
                        actions: {
                            action: {
                                activity:'or',
                                operation:{
                                    name:'fffff',
                                    id:'out',
                                    number:'10'
                                },
                                period:'4'
                            }
                        },
                    }
                }
            ]
        };

xml输出：

我需要的输出是：

        <period>6</period>
      </action>
    </actions>

如您所见，它们是需要单独标识的父“对象”中的多个对象，但是子对象“参数”中的属性需要合并为单个子对象。有什么可行的方法吗？
