Data conversion from document to relational database

I'm trying to convert some law texts into relational tables. I've exhausted all online resources that's why I decided to ask this question for I'm clueless about what to do next.
I have a sentence that's saved to db that follows this structure:
Title -> Chapter -> Article -> Section -> Subsection -> Sentence
The problem is that a sentence can be anywhere & any item in the structure doesn't have to have a parent:
Ex1:
Title 1
sentence 1
sentence 2
sentence 3
Chapter 1
sentence 4
Chapter 2
Article 1
sentence 5
Section 1
Subsection 1
sentence 6
Ex2:
Article 1
sentence 7
sentence 8
Section 1
sentence 9
sentence 10

for instance, a sentence can have a title & be placed directly into it or it can have no title but a chapter and a subsection. they're basically used to identify law texts and by design they're made like that.

Then create your tables with a column let's call itsentence INT NULLreference theSentencestable.

what if multiple sentences have the same title or the same chapter ?

It depends on your needs there, if so create a column in theSentencestable, and if it's a many to many relationship you will need another table for that.

The presented case is a good example when document-oriented data model fits better that relational one. However, you always can map any hierarchical database schema to relational one. For example.
item_types
----------
id name
--- ----------
1 Title
2 Chapter
3 Article
4 Section
5 Subsection
6 Sentence
textes
------
id name
--- -----------
1 Test text 1
2 Test text 2
text_structure (Key: text_id + item_index)
--------------
text_id item_index parent_index item_type content
------- ---------- ------------ --------- ------------
1 1 NULL 1 Title 1
1 2 1 6 sentence 1
1 3 1 6 sentence 2
1 4 1 6 sentence 3
1 5 1 2 Chapter 1
1 6 5 6 sentence 4
...
2 1 NULL 3 Article 1
2 2 1 6 sentence 7
2 3 1 6 sentence 8
2 4 1 4 Section 1
2 5 4 6 sentence 9
