/**
* Iterates over all sibling nodes of a given node, typically used to process
* each child of a specific parent node.
*
* This function takes a starting node (expected to be a parent node like <states>)
* and iterates through all of its child nodes.
* It calls a user-provided callback function for each child node that is an
* element node (ignores text and other types of nodes).
*
* @param node The starting node whose siblings (children) will be iterated
* over. This node is not processed by the callback, only its siblings are.
* @param processNode A callback function that will be called for each sibling
* node. This function should have a signature of
* void functionName(xmlNodePtr node, void* userData), where
* 'node' is the current sibling element node, and
* 'userData' is a pointer to user-defined data passed
* through iterateSiblings.
* @param userData A void pointer to user-defined data. This can be used to pass
* additional information to the callback function. It is passed
* directly through to the callback function as its second argument.
