`@xmlelement` is a decorator in Python used in the `lxml` package to define a class attribute as an XML element.
`@xmlelement` takes the name of the XML element as its argument.
Here's an example usage:
```python
from lxml import etree
class Person:
@xmlelement
def name(self):
return self._name
def __init__(self, name):
self._name = name
p = Person("John")
element = etree.Element("person")
element.append(p.name.toxml())
print(etree.tostring(element, pretty_print=True).decode())
```
This will output the following XML:
```xml
<person>
<name>John</name>
</person>
```
In this example, the `name` method of the `Person` class is decorated with `@xmlelement("name")`, which specifies that it should be treated as an XML element with the name "name". The `name` method returns the value of the `_name` attribute, which is set in the constructor. Finally, in the `__init__` method, an instance of `Person` is created with the name "John", and the `name` element is added to an XML element called `person`. The resulting XML is then printed to the console.
