python - XML error object has no attribute 'cssselect' -

the following not appear parse xml data correctly or doing wrong.

this code being run.

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)     status = h.cssselect('itagg_delivery_receipt status').text_content()     return httpresponse(status) 

the error:

attributeerror: 'lxml.etree._element' object has no attribute 'cssselect' status

this xml document being sent:

 <?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 have dumped out str(h) , looks <element 0x7fd341e93870="" at="" itagg_delivery_receipt=""></element>

here's how thing want xpath:

>>> h.xpath('status/text()') ['delivered'] 

so little helper function in code:

def first(seq,default=none):   item in seq:     return item   return default  ...  status = first(h.xpath('status/text()'))
