XML文件的读取----cElementTree

XML文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<tokenxml>
  <tokenspec>
    <spec id="TOTP01">
      <otplen>6</otplen>
      <intervaltime>60</intervaltime>

    </token>
  </tokenlist>
</tokenxml>

读取XML代码：

def xmltest(xmlFile):
    import xml.etree.cElementTree as ET#cElementTree是ElementTree的C实现版本，速度更快
    tree = ET.parse(xmlFile)
    root = tree.getroot()
    print root.tag, "---", root.attrib  
    #for elem in tree.iter(tag='token'):#此方法和下面的方法结果一致，范围比较大
    for elem in root.find('tokenlist').findall('token'):#此方法精确到具体的元素
        print elem.tag,':', elem.attrib
        print "sn:%s, specid:%s" % (elem.get('sn'), elem.get('specid'))
        print "    seed:", elem.find("seed").text
        print "    iv:", elem.find("iv").text
        print "    mac:", elem.find("mac").text
        print 
if __name__ == '__main__':
　　xmltest('C:\Users\tester_cp\Desktop\test.xml')

结果：
