Create "Table of Contents" based on URL

[tsari]

The existing TOC macro (TocMacro) uses the headline (h1 to h6) to create the table of contents. This results in a very confusing toc structure, because a headline h1 on a page on the 3rd level will be displayed on the first level of the toc.

Page structure with used headlines on the page:

page1(h3)/page2(h4)/page3(h2)
         /page2(h4)/page4
                   /page4(h1)/page5(h1)

Resulting TOC from the existing macro:

            page1 h3
                page2 h4
        page3 h2
    page4 h1
    page5 h1

My planns for an improved macro are to focus the toc creation on the url. So the resulting TOC should look likes this.

    page1 h3
        page2 h4
            page3 h2
            page4 h1
                page5 h1

So what should the macro do?

• create the toc structure based on the url structure
  
• use the first headline on each page as text for the toc entry
  
• allow the user to specify the depth of the toc
  

Thanks for your help

Could you please check if my requirements are realizable?
