Search a nested array.

This will recurse through n-deep arrays, storing a collection of matches.

Parameters

$name: String name of the item to search for. If searching for an atribute, prepend this with '#'. If name = '*', any element name that does not begin with '#' will be matched.

$items: An associative array of items to seek.

$value: An (optional) value to search for. If this is specified, both name and value must be matched before an item is considered a match.

$matches: An array of matches. This is typically only used when recursing. Don't use it unless you know what you are doing.
