<?xml version = "1.0" encoding = "utf-8"?>
<root>
    <body name="lyc">
        <age>110</age>
    </body>
    <body name = "l" age = "10">
    </body>
</root>

#coding=UTF8
 
from xml.etree import ElementTree
 
#xmlText = open("xml.txt").read()
#root = ElementTree.fromstring(xmlText)
 
root = ElementTree.parse("xml.txt")
bodys = root.getiterator("body")
 
#getiterator方法获取
print "getiterator"
print bodys
print dir(bodys[0])
print "attrib:",bodys[0].attrib
print "tag:",bodys[0].tag
print "text",bodys[0].text
#getchildren方法获取
print "getchildren"
children = bodys[0].getchildren()
print children
print "attrib:",children[0].attrib
print "tag:",children[0].tag
print "text:",children[0].text
#find
print "find"
children = root.find("body")
print children
print "attrib:",children.attrib
print "tag:",children.tag
print "text:",children.text
#findall 
print "findall"
children = root.findall("body")
print children
print "attrib:",children[0].attrib
print "tag:",children[0].tag
print "text:",children[0].text

aa = xml.dom.minidom.parseString(response_res).documentElement.getElementsByTagName(‘string‘)[0].childNodes[0].data
doc = etree.XML(aa)
doc.xpath("//BoardData")[0].getchildren()[0].text
