parse a special xml in python
- by zhaojing
I have s special xml file like below:
<alarm-dictionary source="DDD" type="ProxyComponent">
<alarm code="402" severity="Alarm" name="DDM_Alarm_402">
<message>Database memory usage low threshold crossed</message>
<description>dnKinds = database
type = quality_of_service
perceived_severity = minor
probable_cause = thresholdCrossed
additional_text = Database memory usage low threshold crossed
</description>
</alarm>
...
</alarm-dictionary>
I know in python, I can get the "alarm code", "severity" in tag alarm by:
for alarm_tag in dom.getElementsByTagName('alarm'):
if alarm_tag.hasAttribute('code'):
alarmcode = str(alarm_tag.getAttribute('code'))
And I can get the text in tag message like below:
for messages_tag in dom.getElementsByTagName('message'):
messages = ""
for message_tag in messages_tag.childNodes:
if message_tag.nodeType in (message_tag.TEXT_NODE, message_tag.CDATA_SECTION_NODE):
messages += message_tag.data
But I also want to get the value like dnkind(database), type(quality_of_service), perceived_severity(thresholdCrossed) and probable_cause(Database memory usage low threshold crossed
) in tag description.
That is, I also want to parse the content in the tag in xml.
Could anyone help me with this?
Thanks a lot!
