this xml

 <?xml version="1.1" encoding="iso-8859-1"?> <itagg_delivery_receipt> <version>1.0</version> <msisdn>447889000000</msisdn> <submission_ref> 845tgrgsehg394g3hdfhhh56445y7ts6</ submission_ref> <status>delivered</status> <reason>4</reason> <timestamp>20050709120945</timestamp> <retry>0</retry> </itagg_delivery_receipt>

i don't have control on xml document comes sms company.

you'll have encode , force same encoding in parser:

from lxml import etree lxml.etree import fromstring  if request.post:     xml = request.post['xml'].encode('utf-8')     parser = etree.xmlparser(ns_clean=true, recover=true, encoding='utf-8')     h = fromstring(xml, parser=parser)      return httpresponse(h.cssselect('delivery_reciept status').text_content())
