Siblings

[dvv]

Hello,
Wonder how do I address a sibling node in predicates, if ever?
TIA,

There's no "siblings" concept in jspath.
Could you provide a real example where you need to select something depending on siblings? Maybe it can be done via something else.

[dvv]

Sure.
Say I have an array of records describing a route. Each record contains starting and ending points coordinates. I want to ensure the ending point of record X matches the starting point of record X+1.

[dfilatov]

Sorry, currently it's impossible to point to the siblings.
Btw, do you want to select such items or just ensure?

[dvv]

I see.
I do understand this tool is for fetching and I should possibly look at schema validators then. But to ensure the said condition holds means the selection of such siblings contains all siblings, right? So it is possible afaiks to use the tool for both cases.

[dvv]

Seems, apriori, that if you exposed the index of the current node in array as say $I one could access siblings by subscribing parent node, no?
Smth like foo{x==../foo[$I+1].x}

There's no "parent" selector as well, as json unlike xml has no parents' relations.

I too, coming from xslt proc, need a parent selector and siblings.
I think that json has parents relations in the same way xml does

Actually, it doesn't.
