Question

First : am a new beg. using python..so please help me out.I’m trying to read a XML file using Python. My xml file name is rgpost.xml

<volume name="sp" type="span" operation="create">
    <driver>HDD1</driver>
</volume>

My code :

import xml.etree.ElementTree as ET
doc = ET.parse("rgpost.xml")
s = doc.find("volume")
print s.attrib["name"]

While running this am getting error :

sp:~# python volume_check.py volume  
Traceback (most recent call last):  
  File "volume_check.py", line 13, in <module>  
    print s.attrib["name"]  
AttributeError: 'NoneType' object has no attribute 'attrib'

Thanks in advance

Life is much easier if you get the root:

>>> import xml.etree.ElementTree as ET
>>> doc = ET.parse("rgpost.xml")
>>> root = doc.getroot() # <--- this is the new line
>>> root
<Element 'volume' at 0x1004d8f10>
>>> root.keys()
['operation', 'type', 'name']
>>> root.attrib["name"]
'sp'
>>> root.get("name")
'sp'
