Excellent work! I made a tab version with phrases (深度提取) below.
Ideally if you 1) keep audio tags intact (do not remove it) 2) insert the numeric id (the file name in original data) such as 1,2, 8 etc, as an attribute like <h1 class=“whole” id=“title” oedid=“123456”> the tabs will be sorted in chronological order. Currently sorted in order of appearance in your mdx, I will create one with audio (offline and online) and correct tab order.

Sorry no GD support here. The content is valid html, so it is puzzling to me why GD doesn’t work.
