Javascript来提取分支和叶信息

我是JS方面的新手，我起草了一个JS代码来解析和创建HighChart选项结构。XML文件包含以下格式的内容

系列->向下展开->数据->系列->向下展开->数据…

最后一个“数据”分支将具有“点”节点。下面是我通过Jquery通过AJAX调用收到的XML（filename:ex.XML）文件：

            </series>
        </data>
</chart>

与XML树结构格式相同。然后将此系列结构设置为HighChart选项：

options.series.push(seriesOptions);

其中选项已在JS脚本中定义

因此，我通过XML树遍历每个系列->每个向下钻取->每个数据->如果有系列，则遍历重复系列->每个向下钻取->每个数据->设置数据点：

$.get('ex.xml', function(xml) {
                    var $xml = $(xml);
                    $xml.find('chart categories name').each(function(i, category) {
                            options.xAxis.categories.push($(category).text());
                    });
                    chart.setTitle.push($xml.find('chart name').text());
                    $xml.find("chart data series").each(function(i, series){
                                            var seriesDownSearch = function(){
                                                    var series = $(this);
                                                    var seriesOptions = {
                                                            y: parseInt(series.find('y').text()),
                                                            drilldown : []
                                                            }
                                                    series.find("drilldown").each(function(i, drilldown){
                                                            //set drilldown name leaf,categories branch name leaf and data branch
                                                            $(drilldown).find("data").each(function(i, data) {
                                                                    //set data point and loop if series branch is present
                                                                    $(data).find("series").each(seriesDownSearch);
                                                            });
                                                    })
                                            }();
                   });
});

我的问题是如何将注释代码设置和创建为/。请注意，'name leaf、categories branch name leaf和data branch'必须是'drilldown'中定义的'data'元素的'drilldown'元素和'option'。这样就可以在一个结构下访问它们

提前感谢

。。那么，您只是想用javascript解析XML？是的，但我还必须生成HighChart数据选项？

$.get('ex.xml', function(xml) {
                    var $xml = $(xml);
                    $xml.find('chart categories name').each(function(i, category) {
                            options.xAxis.categories.push($(category).text());
                    });
                    chart.setTitle.push($xml.find('chart name').text());
                    $xml.find("chart data series").each(function(i, series){
                                            var seriesDownSearch = function(){
                                                    var series = $(this);
                                                    var seriesOptions = {
                                                            y: parseInt(series.find('y').text()),
                                                            drilldown : []
                                                            }
                                                    series.find("drilldown").each(function(i, drilldown){
                                                            //set drilldown name leaf,categories branch name leaf and data branch
                                                            $(drilldown).find("data").each(function(i, data) {
                                                                    //set data point and loop if series branch is present
                                                                    $(data).find("series").each(seriesDownSearch);
                                                            });
                                                    })
                                            }();
                   });
});
