HTML to EPUB TOC Creation XPath

[HoushaSen]

I am new to the forum, and tried to search if anyone had similar question in the past and couldn't quite find exactly what I need, so I hope this is not duplicate.

I have mutiple HTML files that I like make into a single EPUB book. Following the guide, I was able to create EPUB book and created main TOC manually i.e. link to each web pages.

Now, the each web pages are organized in specific manner, but unforunately not in manner such that simple xpath syntax that the Calibre helper generate can handle. I wonder if someone can help me the actual syntax I need to get Subcategories parsed out from the following formatted HTML when converting to EPUB.

<div class="HNUM">Chapter 2</div>
<div class="HD">TITLE of Chapter 2</div>
</div>
<div class="BY">
<div class="PN">Author</div>
</div>
</div>
<div class="TBD">
<div class="TLV1 TLV1-noHD" id_xpath="/CHAPTER[1]/TBD[1]/TLV1[1]">
<div class="P">Blah Blah</div>
</div>
<div class="TLV1" id_xpath="/CHAPTER[1]/TBD[1]/TLV1[2]">
<div class="HD">Subcategory Title</div>
<div class="P">Blah Blah</div>
<div class="TLV2" id_xpath="/CHAPTER[1]/TBD[1]/TLV1[2]/TLV2[1]">
<div class="HD">Subsubcategory Title</div>
<div class="P">Blah Blah</div>

So as you can see above, essentially the site is organized in such that level 1 subcategory is in the div class="TLV1", and subcategory level 2 is under "TLV2"

So ideally I want to have EPUB version to have

Chapter 1
-Subcategory 1
--Subsubcategory 1-1
--Subsubcategory 1-2
-Subcategory 2
Chapter 2

It looks like the site developer was kind enough to give id_xpath tag, which essentially gives me the path such as /CHAPTER[1]/TBD[1], but issue here is actual TITLE is under <div class="HD">

So I believe what I need to have calibre select
Subcategory level 1 as
<DIV class="TLV1">'s child <div class = HD> but have no idea how to do this.

Please help

Have a look at this (And I don't believe Xpath is really involved)
