python lxml添加一个保持所有父树的子元素

from lxml import etree

root = etree.Element("root")

child = etree.Element("child")

root.append(child)

new_parent = etree.Element("new_parent")
new_parent.append(child.getparent())

from lxml import etree

# 创建根元素
root = etree.Element("root")

# 创建子元素
child = etree.Element("child")

# 将子元素添加到根元素中
root.append(child)

# 创建新的父元素
new_parent = etree.Element("new_parent")

# 将子元素的父元素添加到新的父元素中
new_parent.append(child.getparent())

# 打印结果
print(etree.tostring(new_parent, pretty_print=True).decode())
