如何正确解析此html并将其显示在可扩展的RecyclerView中

Question

我正在尝试使用Expandable Recyclerview和Jsoup来解析以下内容：

<div class="book-column">
   <div class="group">
      <h3 class="group-title">Authors</h3>
      <ul class="book-specs-list">
         <li>
            <strong class="book-term">Written with</strong>
            <div class="book-attr-value">
               <span class="book-1co">Tablet</span>
            </div>
         </li>
         <li>
            <strong class="book-term">Model</strong>
            <div class="book-attr-value">
               <span class="book-1co">Android</span>
            </div>
         </li>
         <li>
            <strong class="book-term">Published</strong>
            <div class="book-attr-value">
               <span class="book-1co">December 1945</span>
            </div>
         </li>
         <li>
            <strong class="book-term">Released</strong>
            <div class="book-attr-value">
               <span class="book-1co">December 1945</span>
            </div>
         </li>
         <li>
            <strong class="book-term">Status</strong>
            <div class="book-attr-value">
               <span class="book-1co">Available</span>
            </div>
         </li>
      </ul>
   </div>
   <div class="group">
      <h3 class="group-title">Design</h3>
      <ul class="book-specs-list">
         <li>
            <strong class="book-term book-tooltip">Type</strong>
            <div class="book-attr-value">
               <span class="book-1co">Crime fiction</span>
            </div>
         </li>
         <li>
            <strong class="book-term">Dimensions</strong>
            <div class="book-attr-value">
               <span class="book-1co">211*123*8.3mm</span>
            </div>
         </li>
         <li>
            <strong class="book-term">Colors</strong>
            <div class="book-attr-value">
               <span class="book-1co">Green</span>
            </div>
         </li>
      </ul>
   </div>
</div>

**GadChildItem**

GadParentAdapter

public class GadParentAdapter extends ExpandableRecyclerAdapter<GadParentViewHolder, GadChildViewHolder> {

        View parentView = mInflater.inflate(R.layout.gad_parent_feat, parentViewGroup, false);
        return new GadParentViewHolder(parentView);
    }

    @Override
    public GadChildViewHolder onCreateChildViewHolder(ViewGroup childViewGroup) {
        View childView = mInflater.inflate(R.layout.gad_child_feat, childViewGroup, false);
        return new GadChildViewHolder(childView);
    }

    @Override
    public void onBindParentViewHolder(GadParentViewHolder parentViewHolder, int position, ParentListItem parentListItem) {
        GadParentItem gadParentItem = (GadParentItem) parentListItem;
        parentViewHolder.bind(gadParentItem);
    }

    @Override
    public void onBindChildViewHolder(GadChildViewHolder childViewHolder, int position, Object childListItem) {
        GadChildItem gadChildItem = (GadChildItem) childListItem;
        childViewHolder.bind(gadChildItem);
    }
}

值得注意的是，我正在解析的数据在数量和内容方面是100％动态的，我无法编辑html。

拜托，您知道问题可能是什么吗？
