I have a question: How to get span content and store it in an array_html/css_WEB-ITnose

                4  
                Germany
            
        
    

 
请教个问题，获取ul下li的值问题，我使用下面的代码获取到li值了，但包含着span呢，调试输出li内容时输出结果为：
4   Germany
其实我想获取到span里的内容，再去掉 后存到数组，也就是取出4、Germany存到数组。目前只会这些了，后面的不会了，请教下，这该怎么实现啊？

 var ulNode = document.getElementById("rightList");
  var childrens = ulNode.childNodes;
  var len = childrens.length;
  for(var i=0;i   {
      //alert(childrens[i].nodeName);
      //alert(childrens[i].innerHTML); //这两条语句是调试用的，想把span内容存到数组里，随表单提交，该怎么实现啊  
  }

<div id="sample_2" class="sampleDiv"><ul id="leftList">           <li class="simpleItem">                <span class="idCol">2  </span>                <span class="nameCol">United States</span>            </li>            <li class="simpleItem">                <span class="idCol">3  </span>                <span class="nameCol">Britain</span>            </li>            <li class="simpleItem">                <span class="idCol">4  </span>                <span class="nameCol">Germany</span>            </li>        </ul>    </div>     <script>        var lis = document.getElementById('leftList').getElementsByTagName('li');        var rst = [];        for (var i = 0; i < lis.length; i++) {            rst.push(lis[i].innerHTML.replace(/<[^>]+>| |\s/gi, ''));//用正则去掉html标签和 及空白内容        }        alert(rst.join('\n'))    </script>
