```python
vllm_mlx.tool_parsers.qwen3_xml_tool_parser.StreamingXMLToolCallParser._reset_xml_parser_after_tool_call() -> not annotated
```

Each tool_call is treated as a separate XML document, so we need to reset the parser after each tool_call.

**Parameters**

This callable has no explicit inputs.

**Returns**

- Type: `not annotated`

**Exceptions and behavior**

Method `StreamingXMLToolCallParser._reset_xml_parser_after_tool_call` updates `self.parser`, `self.last_completed_call_id`, `self.current_call_id`, `self.current_function_name`; calls `ParserCreate`, `self.setup_parser`.
