lxml findall和逆序

Question

如何以相反的顺序打印所有findall元素？

labels = tree.findall(label)

for label in labels:
     print etree.tostring(label)

Answer 1

有一个reversed功能：

for label in reversed(labels)

Answer 2

或者类似这样的事情：

labels = ET.findall(label)
alist =[]
for one_label in labels:
     alist.append(etree.tostring(one_label))

print sorted(alist, reverse=True)
