Extracting data and preserving hierarchy information

I'm trying to figure out how to loop through a page structure and still maintain some information about the hierarchy. I have extracted a dataset, and within the data set is a number of entries that are categorized like this.

Category A
Sub-category 1
Entry 1 Name - Entry 1 Description - Entry 1 Attribute
Entry 2 Name - Entry 2 Description - Entry 2 Attribute
Entry 3 Name - Entry 3 Description - Entry 3 Attribute
Sub-category 2
Entry 4 Name - Entry 4 Description - Entry 4 Attribute
Entry 5 Name - Entry 5 Description - Entry 5 Attribute
Category B
Sub-category 3
Entry 6 Name - Entry 6 Description - Entry 6 Attribute
Entry 7 Name - Entry 7 Description - Entry 7 Attribute
Sub-category 4
Entry 8 Name - Entry 8 Description - Entry 8 Attribute

what I want to do is collect data like this

Entry 1 Name - Entry 1 Description - Entry 1 Attribute Category - A Sub-category - 1
Entry 2 Name - Entry 2 Description - Entry 2 Attribute Category - A Sub-category - 1
Entry 3 Name - Entry 3 Description - Entry 3 Attribute Category - A Sub-category - 1
Entry 4 Name - Entry 4 Description - Entry 4 Attribute Category - A Sub-category - 2
Entry 5 Name - Entry 5 Description - Entry 5 Attribute Category - A Sub-category - 2
Entry 6 Name - Entry 6 Description - Entry 6 Attribute Category - A Sub-category - 3
Entry 7 Name - Entry 7 Description - Entry 7 Attribute Category - B Sub-category - 3
Entry 8 Name - Entry 8 Description - Entry 8 Attribute Category - B Sub-category - 4

I have figured out how to extract the data from the dataset but not how to preserve the category and subcategory data.

any help would be great.

Thanks
