Parsing XML - Newbie help

[rh0dium]

Hi all,

I am relatively new to python and certainly new to XML parsing.  Can
some show me how to get the product text out of this?  Really I want to
know this has 2 processors and the are AMD Opteron(tm) Processor 250

I have gotten this far...

class HWParser:

    def __init__(self):
        if os.path.isfile(LSHW):
            lshw=Exec.Exec(LSHW)
            lshw.execute('-xml')
        else:
            print "lshw does not exist", LSWH
            return "Unknown"

        self.data  = lshw.read()
        self.error = lshw.error()
        self.exit  = lshw.poll()

        if self.error:
            print "Error Exist", self.error
            return
        else:
            self.xml = minidom.parseString(self.data)
            self.xml.normalize()

    def p (self):
        print self.xml.toxml()

If anyone can help me out that would be great!
