Python: Get specific node values and attributes using lxml + objectify + findall or fromstring

I took out and cut a portion of an XML source from NVD and below is the snippet:

<?xml version='1.0' encoding='UTF-8'?><nvd xmlns="http://nvd.nist.gov/feeds/cve/1.2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://nvd.nist.gov/feeds/cve/1.2 http://nvd.nist.gov/schema/nvdcve.xsd" pub_date="2014-07-01" nvd_xml_version="1.2"><entry CVSS_base_score="6.4" CVSS_exploit_subscore="10.0" CVSS_impact_subscore="4.9" CVSS_score="6.4" CVSS_vector="(AV:N/AC:L/Au:N/C:P/I:P/A:N)" CVSS_version="2.0" modified="2014-06-30" name="CVE-2011-1381" published="2014-06-27" seq="2011-1381" severity="Medium" type="CVE"><desc><descript source="cve">Unspecified vulnerability in IBM OpenPages GRC Platform 6.1.0.1 before IF4 allows remote attackers to bypass intended access restrictions via unknown vectors.</descript></desc></entry><entry CVSS_base_score="3.5" CVSS_exploit_subscore="6.8" CVSS_impact_subscore="2.9" CVSS_score="3.5" CVSS_vector="(AV:N/AC:M/Au:S/C:P/I:N/A:N)" CVSS_version="2.0" modified="2014-06-30" name="CVE-2014-4669" published="2014-06-28" seq="2014-4669" severity="Low" type="CVE"><desc><descript source="cve">HP Enterprise Maps 1.00 allows remote authenticated users to read arbitrary files via a WSDL document containing an XML external entity declaration in conjunction with an entity reference within a GetQuote operation, related to an XML External Entity (XXE) issue.</descript></desc></entry></nvd>

As mentioned on the title of this question and for the related snippet above, I just want to get the value and the attrib of the 'descript' node. I tried using the findall method but it's returning an empty list:

root = etree.fromstring(open("c:/temp/CVE/sample.xml").read()).getroottree().getroot()root.findall('entry')

This returns:

[]

When I print the tag of the root, here's what it returns:

'{http://nvd.nist.gov/feeds/cve/1.2}nvd'

I also tried printing the tags of the immediate parent and its children:

for e in root.iterchildren():print "Immediate parent : %s" % e.tagchildren = e.getchildren()for c in children : print "\t\tchildren : %s" % c.tag

Here's what it returns:

Immediate parent : {http://nvd.nist.gov/feeds/cve/1.2}entry    children : {http://nvd.nist.gov/feeds/cve/1.2}descImmediate parent : {http://nvd.nist.gov/feeds/cve/1.2}entry    children : {http://nvd.nist.gov/feeds/cve/1.2}desc

Again, what I just want is to get the attrib and value of the 'descript' node.Any ideas are greatly appreciated. Thanks in advance!
