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)
