ElementTree handling nested tag

[tekion]

All,
I have the following xml tag:
<event>
<resource_access>
<action>httpRequest</action>
<httpurl>HTTP://cmd.wma.ibm.com:80/</httpurl>
<httpmethod>GET</httpmethod>
<httpresponse>200</httpresponse>
</resource_access>
</event>

I am interested in:
<action>httpRequest</action>
<httpurl>HTTP://cmd.wma.ibm.com:80/</httpurl>
<httpmethod>GET</httpmethod>
<httpresponse>200</httpresponse>
as well as the upper layer tag. How do I get at the nest tag listed
above? Thanks.

What is the "upper layer tag"? And what do you actually want to "get"?
The text-values? Or do you want to just create a document that just
consists of the resource_access tag?

Then this should help:


from xml.etree.ElementTree import *

doc = """
<event>
<resource_access>
<action>httpRequest</action>
<httpurl>HTTP://cmd.wma.ibm.com:80/</httpurl>
<httpmethod>GET</httpmethod>
<httpresponse>200</httpresponse>
</resource_access>
</event>
"""


doc = fromstring(doc)

resource_access = doc.find("resource_access")
print tostring(resource_access)

Diez,
This is the sample format from the doc. I the whole log file has this
xml formated beginning and ending in the event tag. Is this something
ElemenTtree can handle or is it better to user XSLT? Thanks.

Handle *what*? Can it read it? Yes. Can it extract data from it?
Yes. You still haven't said what you actually *want* with all this.

I wan to get the value of these tags:

<httpurl>HTTP://cmd.wma.ibm.com:80/</httpurl>
<httpmethod>GET</httpmethod>
<httpresponse>200</httpresponse>

You asked for what the upper layer tags are. The upper layer tags I
am referring for below tags are any tag that is above it.

<httpurl>HTTP://cmd.wma.ibm.com:80/</httpurl>
<httpmethod>GET</httpmethod>
<httpresponse>200</httpresponse>

IE, for the upper upper are: <action>httpRequest</action> and <event>
tags.

tags.

Based upon the structure you posted, <action> is NOT an "upper
level" tag -- it is a peer to the three you state you want to retrieve.

I'm no expert at XML or elementTree but...

You retrieve the <event> tag and from it extract its contents as a
node; from that node you retrieve the <resource...> tag and extract its
contents... From that node you can retrieve the three peer tags by
asking for them by name.

That's not true. action is on the same level as the others. And what you
you want to "get" from the upper layer tags?
