format_as_xmlc t || j | | }|s-|j !|dnd}|j t || S |t j || t j |d S )a Format a Python object as XML.
This is useful since LLMs often find it easier to read semi-structured data (e.g. examples) as XML,
rather than JSON etc.
Supports: `str`, `bytes`, `bytearray`, `bool`, `int`, `float`, `date`, `datetime`, `Mapping`,
`Iterable`, `dataclass`, and `BaseModel`.
Args:
obj: Python Object to serialize to XML.
root_tag: Outer tag to wrap the XML in, use `None` to omit the outer tag.
item_tag: Tag to use for each item in an iterable (e.g. list), this is overridden by the class name
for dataclasses and Pydantic models.
include_root_tag: Whether to include the root tag in the output
(The root tag is always included if it includes a body - e.g. when the input is a simple value).
none_str: String to use for `None` values.
indent: Indentation string to use for pretty printing.
Returns: XML representation of the object.
Example:
```python {title="format_as_xml_example.py" lint="skip"}
from pydantic_ai.format_as_xml import format_as_xml
print(format_as_xml({'name': 'John', 'height': 6, 'weight': 200}, root_tag='user'))
'''
John
6
200
'''
```
