Drill down unknown levels JSON response

[robertybob]

Hi

I am retrieving a JSON response for a menu (via NewtonSoft) and am successfully parsing it for use.

The problem is that the end data I need could be 3 levels down or could be 7 levels down. How do I efficiently go about drilling down until I reach the final node?

The main issue is that I have no way to know at what point the path will end so I cannot just drill down 5 levels each time - every single path can have different number of levels.

So each bit of data could either be the end node or it could contain another set of nodes.

I need an efficient way to do the following sort of thing so I can build the menu tree.

For Each result As myresult In jsonresp.data
    If result.hasnodes Is Nothing Then
        ' store the data and exit
    Else
        ' repeat process on all nodes on next level
    End If
Next
 

Hope that makes some sort of sense! Many thanks!

Put a while loop inside your for loop.
pseudo

 For Each result As myresult In jsonresp.data
tmp=result
while tmp.hasnodes
 tmp=nextnode
end while
Next
