如何从WebDriver获取当前WebElement上的CSS选择器字符串

Question

我想在当前的WebElement上重用CSS选择器。有没有办法解决它？原因是我想在条件满足时重新选择元素，以便我想添加＆＃34;＆gt; *＆＃34;在By.cssSelector（）中获取子DOM元素。到目前为止，我只能执行tagName（），但没有保证选择正确的。

List<WebElement> webElements = DMDriver.findElements(By.cssSelector(cssSelectorNode));
  WebElement selectedRootFolder = null;

  if (webElements.size() > 0)
  {
    for (WebElement webElement : webElements)
    {
      if (webElement.getText().trim().equals(strFolder))
      {
        webElement.findElement(By.tagName("..."));

HTML代码（由Angular JS生成）

<div class="folder-rows-wrapper" ng-nice-scroll="" style="overflow: hidden;" tabindex="1">

<div class="ya-node" ya-node="">
    <ul class="list-unstyled ng-scope" ng-hide="node.collapsed">
        <li class="node ng-scope" ng-repeat="node in node.$children">
            <div class="" ng-show="node.$hasChildren">
