PHP loop through array and split into seperate arrays

Hi I have this PHP array of Amazon Sub Categories what I am trying to do is loop through the array and split into 3 seperate ones,

Heres the Array, and needs to be split into 3 arrays $request, and all the children under it $subCats and final variable $Ancestors. The $subCats will contain all the [Children][BrowseNode]. Its driving me mad I cant seem to loop through correctly.

Any thoughts people. Cheers in advanced.

                        )

                )

        )

)

This should do it:

$request = your_main_array['request'];
$subCats = your_main_array['BrowseNode']['Children']['BrowseNode'];
$Ancestors = your_main_array['BrowseNode']['Ancestors']

['Children']['BrowseNode'] and ['Ancestors'] are in a [BrowseNode] Array under you main array.
