get_empty
Find the next empty container node within a hierarchical XML document's subtree using breadth-first search. Specify a file path and starting node ID to locate nodes without children for structured content insertion.
Instructions
Find next container node without children within a specific node's subtree (BFS order)
Args: file_path (str): Path to the HNPX document node_id (str): ID of the node to search within
Returns: str: XML representation of the next empty container node or a message if none found

Implementation Reference
- src/hnpx_sdk/tools.py:53-76 (handler)The handler function implementing the 'get_empty' tool logic. It parses the HNPX document, finds the starting node, searches for the first empty container in BFS order using hnpx.find_first_empty_container, and returns its XML or a message if none found.
