值得一看lxml.objectify。
xml = """<main>
<object1 attr="name">content</object1>
<object1 attr="foo">contenbar</object1>
<test>me</test>
</main>"""
from lxml import objectify
main = objectify.fromstring(xml)
main.object1[0] # content
main.object1[1] # contenbar
main.object1[0].get("attr") # name
main.test # me
或者以另一种方式构建xml结构：
item = objectify.Element("item")
item.title = "Best of python"
item.price = 17.98
item.price.set("currency", "EUR")
order = objectify.Element("order")
order.append(item)
order.item.quantity = 3
order.price = sum(item.price * item.quantity for item in order.item)
import lxml.etree
print(lxml.etree.tostring(order, pretty_print=True))
输出：
<order>
<item>
<title>Best of python</title>
<price currency="EUR">17.98</price>
<quantity>3</quantity>
</item>
<price>53.94</price>
</order>
