如何在python中创建具有头部和正文的xml

import xml.etree.ElementTree as ET

# 创建根元素
root = ET.Element("root")

# 添加头部信息
header = ET.SubElement(root, "header")
header.text = "This is the header"

# 添加正文内容
body = ET.SubElement(root, "body")
body.text = "This is the body content"

# 创建XML树
tree = ET.ElementTree(root)

# 将XML树写入文件
tree.write("output.xml", encoding="utf-8", xml_declaration=True)

from lxml import etree

# 创建根元素
root = etree.Element("root")

# 添加头部信息
header = etree.SubElement(root, "header")
header.text = "This is the header"

# 添加正文内容
body = etree.SubElement(root, "body")
body.text = "This is the body content"

# 创建XML树
tree = etree.ElementTree(root)

# 将XML树写入文件
tree.write("output.xml", pretty_print=True, xml_declaration=True, encoding='UTF-8')
