 问题：nodeName,nodeValue未知 xml动态数据入库，   解决方案:

---->更高效的

nodeName,nodeValue未知 xml 入库方案

xml--->?--->database
json只是过程，不是目的；


想到一种算法是将xml转为string，然后借助正则辅助去处理该string，目测可行但是觉得似乎其不高效；；；；


也许xpath的原理就是上述算法？？

SAX解析多层嵌套XML - donglindonglin的博客 - 博客频道 - CSDN.NET
http://blog.csdn.net/donglindonglin/article/details/51996926

wuser@ubuntu:~/apiamzpy$ python wl.py
<listiterator object at 0x7f6c99c20ed0>
[0, 23, 'w1']
Traceback (most recent call last):
  File "wl.py", line 5, in <module>
    if  t0.next():
StopIteration
wuser@ubuntu:~/apiamzpy$ vim wl.py

l0 = [0,23,'w1']
t0 = l0.__iter__()
print t0
print list(t0)
if  t0.next():
        t0.next()
~

问题：

xml取出所有的nodeName、nodeValue对

0-不高效的方案：0-0-php / python 将xml处理为string；0-1-利用正则处理字符串。
