Multi level ecommerce product scrapping

Describe the problem.

http://poshardware.biz/product-category/card-readers/

Sitemap:
{id:"sitemap code"}

I want to know if

  1. category has items or
  2. category(level 1) has sub category (Level 2) and items or
  3. sub category has another sub category (level 3) nested with items,

how to scrape the same?
In my trial, i have created

  1. element at category level (level 1) and
  2. link to sub category (level 2) at the same level.
  3. Elements have text fields-description and price in level 1
    Is that correct?
    or should define only the lowest level for scraping to work correctly?
    As I get blanks for text field description of test at level 1 but with prices defined at level 1

can you export your sitemap and post it here so I can take a look?

Thank you for your reply.
