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：
