如何使用python解析器创建适当的xml属性

Question

from xml.dom.minidom import parse

dom = parse('abc.xml')

for node in dom.getElementsBy('addr'): 
    print node.toxml()  

我需要添加（属性）以仅打印addr（nmap xml文件中的ip地址）？

<host starttime="1404053959" endtime="1404054014"><status state="up" reason="reset" reason_ttl="254"/> <address addr="ip" addrtype="ipv4"/>

Answer 1

我想补充root标签和127.0.0.1 ， 192.168.0.1展现更多的东西：

from xml.dom.minidom import parse, parseString

data = '''<root>
<host starttime="1404053959" endtime="1404054014">
    <status state="up" reason="reset" reason_ttl="254"/>
    <address addr="ip" addrtype="ipv4">127.0.0.1</address>
</host>
<host starttime="1404053959" endtime="1404054014">
    <status state="up" reason="reset" reason_ttl="254"/>
    <address addr="ip" addrtype="ipv4">192.168.0.1</address>
</host>
</root>'''

#dom = parse('abc.xml')
dom = parseString(data)

for node in dom.getElementsByTagName('address'):
    print ' xml:', node.toxml()
    print 'type:', node.getAttribute('addrtype')
    print 'addr:', node.childNodes[0].data

结果：

 xml: <address addr="ip" addrtype="ipv4">127.0.0.1</address>
type: ipv4
addr: 127.0.0.1
 xml: <address addr="ip" addrtype="ipv4">192.168.0.1</address>
type: ipv4
addr: 192.168.0.1
