本文实例讲述了python比较2个xml内容的方法。分享给大家供大家参考。具体分析如下：
from xml.etree import elementtree
ok=true
main_pid = 10000
loop_depth = 0
def compare_xml(left, right, key_info=’.’):
global loop_depth
loop_depth += 1
if loop_depth == 1: print
if left.tag != right.tag:
print_diff(main_pid, key_info, ‘difftag’, left.tag, right.tag)
return
if left.text != right.text:
print_diff(main_pid, key_info, ‘difftext’, left.text, right.text)
return
leftitems = dict(left.items())
rightitems = dict(right.items())
for k,v in leftitems.items():
if k not in rightitems:
s = ‘%s/%s’ % (key_info, left.tag)
print_diff(main_pid, s, ‘lostattr’, k, “”)
for k,v in rightitems.items():
if k not in leftitems:
s = ‘%s/%s’ % (key_info, right.tag)
print_diff(main_pid, s, ‘extraattr’, “”, k)
leftnodes = left.getchildren()
rightnodes = right.getchildren()
leftlen = len(leftnodes)
rightlen = len(rightnodes)
if leftlen != rightlen:
s = ‘%s/%s’ % (key_info, right.tag)
print_diff(main_pid, s, ‘difflen’, leftlen, rightlen)
return
l = leftlen
