BeautifulSoup XML Python extracting attributes from specific tags

This XML document contains the set of tags events-data. I want to extract information from the most RECENT events-data. For example, in the code below I want to go to the last events-data tag, go down to the event-date tag and extract the text of the date child tag. At the moment I am using BeautifulSoup in Python to traverse this document. Any ideas?

    <?xml version="1.0" encoding="UTF-8"?>
        <first-tag>
          <second-tag>
            <events-data>
               <event-date>
                    <date>20040913</date>
               </event-date>
            </events-data>

          <events-data> #the one i want to traverse to grab date text
             <event-date>
               <date>20040913</date>
             </event-date>
          </events-data> 
         </second-tag>
       </first-tag>

This is using BeautifulSoup 3

import os
import sys

# Import Custom libraries
from BeautifulSoup import BeautifulStoneSoup

xml_str = \
'''
<?xml version="1.0" encoding="UTF-8"?>
    <first-tag>
      <second-tag>
        <events-data>
           <event-date>
                <date>20040913</date>
           </event-date>
        </events-data>

      <events-data>
         <event-date>
           <date>20040913</date>
         </event-date>
      </events-data> 
     </second-tag>
   </first-tag>
'''
soup = BeautifulStoneSoup(xml_str)

event_data_location = lambda x: x.name == "events-data"

events = soup.findAll(event_data_location)
if(events):
    # The last event-data
    print events[-1].text
