XML parsing specific values - Python -


i've been attempting parse list of xml files. i'd print specific values such username value. 

<?xml version="1.0" encoding="utf-8"?> <drives clsid="{8fddcc1a-0c3c-43cd-a6b4-71a6df20da8c}"          disabled="1">   <drive clsid="{935d1b74-9cb8-4e3c-9914-7dd559b7a417}"           name="s:"           status="s:"           image="2"           changed="2007-07-06 20:57:37"           uid="{4da4a7e3-f1d8-4fb1-874f-d2f7d16f7065}">     <properties action="u"                  thisdrive="nochange"                  alldrives="nochange"                  username=""                  cpassword=""                  path="\\scratch"                  label="scratch"                  persistent="1"                  useletter="1"                  letter="s"/>   </drive> </drives>

my script working fine collecting list of xml files etc. below function print relevant values. i'm trying achieve suggested in post. i'm doing incorrectly i'm getting errors suggesting elm object has no attribute text. appreciated.

current code

from lxml import etree et  def read_files(files):     fi in files:         doc = et.parse(fi)         elm = doc.find('username')         print elm.text

doc.find looks tag given name. looking attribute given name.

elm.text giving error because doc.find doesn't find tags, returns none, has no text property.

read lxml.etree docs more, , try this:

doc = et.parse(fi) root = doc.getroot() prop = root.find(".//properties") # finds first <properties> tag anywhere elm = prop.attrib['username']

i've seen in various stackoverflow answers can nth largest element in list doing var nthfromtop = items.orderbydescending().skip(n-1).first(); but wouldn't work if there no duplicates in list? if list contains duplicates, there way nth largest element (or set of elements) using linq? if not, efficient way in c#? to set of items equal nth largest item you'll need group items, order groups, , decrement n group size while n positive. when n reaches zero, you've hit group containing nth largest item. public static ienumerable<t> foo<t>(this ienumerable<t> source, int n) { return source.groupby(x => x) .orderbydescending(group => group.key) .skipwhile(group => { n -= group.count(); return n > 0; }) .first(); }
