如何使用ElementTree获取元素的完整XML或HTML内容？

import xml.etree.ElementTree as ET

tree = ET.parse('your_file.xml')

xml_string = '<your_xml_string>'
root = ET.fromstring(xml_string)

element = tree.find('.//your_element_path')

element_string = ET.tostring(element, encoding='unicode')

import xml.etree.ElementTree as ET

xml_string = '''
<root>
   <element1>
       <child>Child 1</child>
    </element1>
   <element2>
       <child>Child 2</child>
    </element2>
</root>
'''

root = ET.fromstring(xml_string)
element = root.find('.//element1')
element_string = ET.tostring(element, encoding='unicode')

print(element_string)

       <child>Child 1</child>
    </element1>
