Take the candidates and then find criteria the further reduce the matching 
nodes until only those are left that you are interested in:

import xml.etree.ElementTree as ET
 
inv = ET.parse("lshw-a105.xml")
 
nodes = inv.findall(".//node[@class='memory']")
for node in nodes:
    description = node.find("./description")
    if description.text == "System Memory":
        for subnode in node.findall("./node"):
            print(subnode.attrib["id"], subnode.find("./description").text)
        break
