我有以下代码,我需要创建一个嵌套数组,我将生成一个多级有序列表。

var htmlContent2 = '<div id="header"><p class="headpara">Header content</p><p class="one">Lorem ipsum dolor sit amet, consectetur:</p><p class="two">Perferendis iure doloremque iusto adipisci facilis.</p><p class="two">Asperiores impedit officiis cumque molestias at rerum consequuntur!</p><p class="one">More dummy text.</p> <p class="two">Additional dummy text: </p> <p class="three">Asperiores impedit officiis.</p> <p class="three">Lolestiae asperiores ad repellat est obcaecati.</p> <p class="two">Lorem ipsum dolor sit amet.</p> <p class="notelem">Dignissimos maiores facere consequuntur quod.</p> <p class="one">Ea  excepturi aperiam.</p></div>';

var $ = cheerio.load(htmlContent2);
var allList = [];
var manipulatedContent = $('#header').each(function (i, elem) {
    var level1 = [],
        level2 = [],
        level3 = [],
        level4 = [],        
        item1 = $('.one').html(),
        item2 = $('.two').html(),
        item3 = $('.three').html(),
        item4 = $('.notelem').html();
    level1[i] = item1;
    level2[i] = item2;
    level3[i] = item3;
    level4[i] = item4;
    allList.push(item1, [item2, [item3, item4]]);

});
console.dir(allList);

使用我当前的代码,我只能生成以下数组:

[ 'Lorem ipsum dolor sit amet, consectetur:',
  [ 'Perferendis iure doloremque iusto adipisci facilis.',
    [ 'Asperiores impedit officiis.',
            'Dignissimos maiores facere consequuntur quod.']]]

但是想要的结果数组:

['Lorem ipsum dolor sit amet, consectetur:',
    ['Perferendis iure doloremque iusto adipisci facilis.',
        ['Asperiores impedit officiis.',
            ['Dignissimos maiores facere consequuntur quod.']]]];

如何使用JavaScript或任何更好的cheerio.js方法实现这一目标?

我的目标是从格式不佳的html创建一个嵌套的有序列表,如示例内容(htmlContent2)所示。

非常感谢您的帮助。

正如@Chris G评论的那样:

//var htmlContent2 = '';
//var $ = cheerio.load(htmlContent2);
var allList = [];
var manipulatedContent = $('#header').each(function (i, elem) {
    var level1 = [],
        level2 = [],
        level3 = [],
        level4 = [],        
        item1 = $('.one').html(),
        item2 = $('.two').html(),
        item3 = $('.three').html(),
        item4 = $('.notelem').html();
    level1[i] = item1;
    level2[i] = item2;
    level3[i] = item3;
    level4[i] = item4;
    allList.push(item1, [item2, [item3, [item4]]]);

});
console.dir(allList);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="header"><p class="headpara">Header content</p><p class="one">Lorem ipsum dolor sit amet, consectetur:</p><p class="two">Perferendis iure doloremque iusto adipisci facilis.</p><p class="two">Asperiores impedit officiis cumque molestias at rerum consequuntur!</p><p class="one">More dummy text.</p> <p class="two">Additional dummy text: </p> <p class="three">Asperiores impedit officiis.</p> <p class="three">Lolestiae asperiores ad repellat est obcaecati.</p> <p class="two">Lorem ipsum dolor sit amet.</p> <p class="notelem">Dignissimos maiores facere consequuntur quod.</p> <p class="one">Ea  excepturi aperiam.</p></div>
