Javascript 如果找到文本内容，添加 for 循环以忽略列表中的各个节点

Question

我使用 querySelector 和 querySelectorAll 对我的 HTML 文档进行了查询，这会忽略所有 li ，这是代码：

var number2 = number;

var otherSubjRow = document.querySelector("#exploreTable");
if(otherSubjRow) {
var otherSubjCells = Row.querySelectorAll("li");
if (typeof(otherSubjCells) != 'undefined' && Cells != null)
{
l = otherSubjCells.length;
var otherSubjects = ""
var number2 = number;
for (var i = 0; i < l; i++) {

    if (otherSubjCells[i].querySelectorAll("a").length < 1) {
     otherSubjCells[i].innerText + " ");
     otherSubjects += number2 + "." + otherSubjCells[i].innerText + " "; 
     number2++      
  }
}
}

这是我文档的一个片段：

 <table id="exploreTable">
    ...
 <tr>
 <li>
  <a></a>
 </li>
 </tr>
 <tr><td>
 <ul><li>International relations -- Handbook
  <a></a>
 </li></ul>
 </td></tr>
 <tr><td>
 <ul><li>Titles by: Jose, Charles, editor.
  <a></a>
 </li></ul>
 </td></tr>
 <tr><td>
 <ul><li>Series: Policy brief ; no. 2016-03
  <a></a>
 </li></ul>
 </td></tr>
 </table>

问题是我想忽略在我的 for 循环中捕获包含在文本 "Series: " 和 "Titles by: " 开头的所有文本。我正在尝试使用 || 将其添加到此处：

 if (otherSubjCells[i].querySelectorAll("a").length < 1)

但不太确定这样做是否正确。或者在语句中添加另一个 if ？关于如何去做的任何想法？谢谢，干杯！

    <table id="exploreTable">
        <tr>
            <li>
                <a></a>
            </li>
        </tr>
        <tr>
            <td>
                <ul>
                    <li>International relations -- Handbook
                        <a></a>
                    </li>
                </ul>
            </td>
        </tr>
        <tr>
            <td>
                <ul>
                    <li>Titles by: Jose, Charles, editor.
                        <a></a>
                    </li>
                </ul>
            </td>
        </tr>
        <tr>
            <td>
                <ul>
                    <li>Series: Policy brief ; no. 2016-03
                        <a></a>
                    </li>
                </ul>
            </td>
        </tr>
    </table>

    <script>
      const arr = document.getElementById("exploreTable").querySelectorAll('li');
      const result = [].filter.call(arr,(el)=>{
        return !(el.textContent.indexOf("Series:") === 0||el.textContent.indexOf("Titles by:") === 0)
      });
      const resText = result.map((el, index)=>{
         return `${index+1} ${el.textContent}`;
      });
      console.log(result);
      console.log(resText);

    </script>
