lxml findall和反向命令

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

也许是这样的：

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

print sorted(alist, reverse=True) 

Answer 2

有一个reversed功能：

for label in reversed(labels)
