如何在python中基于xsd将xml文件映射到新的xml文件？

pip install xmlschema

import xmlschema
from lxml import etree

xsd_file = "path/to/xsd/file.xsd"
schema = xmlschema.XMLSchema(xsd_file)

xml_file = "path/to/xml/file.xml"
xml_tree = etree.parse(xml_file)
root_element = xml_tree.getroot()

if schema.is_valid(root_element):
    # 如果验证通过，创建新的XML文件
    new_xml_root = schema.encode(root_element)
    new_xml_tree = etree.ElementTree(new_xml_root)
    new_xml_tree.write("path/to/new/xml/file.xml", pretty_print=True)
else:
    print("XML文件不符合XSD定义")
