1-我编写什么代码来获取此代码中的所有“想要访问”元素，没有其他元素，如“一些数据”，只想要 div 类 bestMFdtl2中的元素。

2-如果我想根据选择如何在此代码中包含一些特定元素，我正在使用 html jerico 解析器。请帮助我，那些在阅读代码时遇到问题的人我很抱歉，但你是我认为你喜欢的程序员这个。

3-如何从标签中获取href链接。

<div class='bestMFdtl2 '>
        <div class='tBrd btBrd tbg'>
         <div class='FL eqTle2 wd_182 rtBrd PL10 PR10'><a href='' class='bl_11'><strong></strong></a></div>
       <div class='FL eqTle wd_65 rtBrd PL5 PR5' align='center'><strong>some data</strong></div>
     <div class='FL eqTle wd_83 rtBrd' align='center'>
 <div class='btBrd'><strong>some data</strong> <span style='font-size:8px;'>some data</span></div>

鉴于评论，我相信这就是你所追求的。

var x = document.getElementsByClassName("bestMFdt12");

for (var i = 0; i < x.length; i++){
    var x2 = x[i].getElementsByClassName("b-12");

    for (var j = 0; j < x2.length; j++) {
        //Do something with the elements, access them with "x2[j]", these loops will go through every element within both classes and allow you to process them

        //Example:
        var current = x2[j];
    }
}

这应该得到一个包含所有“bestMFdt12”元素的数组，并为每个元素在里面搜索任何“b-12”元素。在我放置示例的地方，您可以添加代码来处理这些元素。
