python请教一个xml.dom.minidom的问题

[STUDENTzyr]

有个xml文件，大概是这样的，
<TEXT>
<s num = '1' count = '23' >for currentLine in file.readlines</s>
<s num = '2' count = '23' >for currentLine in file.readlines</s>
<s num = '3' count = '23' >for currentLine in file.readlines</s>
<s num = '4' count = '23' >for currentLine in file.readlines</s>
<s num = '5' count = '23' >for currentLine in file.readlines</s>
.....
</TEXT>
我想把<TEXT>中的<s>的内容全都取出来，<s>的属性‘num’和‘count’也取出来，每个xml文件中<s>数目不定。
不知道怎么做好？
问题很菜鸟，希望大家不吝赐教，谢谢^_^

from xml.dom import minidom

xml_string = '''
<TEXT>
<s num = '1' count = '23' >for currentLine in file.readlines </s>
<s num = '2' count = '23' >for currentLine in file.readlines </s>
<s num = '3' count = '23' >for currentLine in file.readlines </s>
<s num = '4' count = '23' >for currentLine in file.readlines </s>
<s num = '5' count = '23' >for currentLine in file.readlines </s>
</TEXT> 
'''

doc = minidom.parseString(xml_string)
nodes = doc.childNodes[0].childNodes[1::2]
for n in nodes:
    print n.getAttribute('num'), n.getAttribute('count')

好象这句
nodes = doc.childNodes[0].childNodes[1::2]
这样写好一点吧
nodes = doc.getElementsByTagName("s")

这样写代码的可适应性和可移槙性都要好一些。
