Vol-get-iter (status="failed" errno="1" reason="Extra content at the end of the document ")

[BALAGUDURU]

Hi,

I am trying to collect volume space info using python and am getting the error message show below. 

<results status="failed" errno="1" reason="Extra content at the end of the document "></results>

Function calling in python : query is a the locaiton where the api call for volume_space is present. Record limit is set to 500 and volume name is a string of vol name.

query.volume_space(apiconnect, recordlimit, volume)

query :

def volume_space(s, recordlimit, volume):
    api = NaElement("volume-get-iter")

    xi = NaElement("desired-attributes")
    api.child_add(xi)

    xi1 = NaElement("volume-attributes")
    xi.child_add(xi1)

    xi2 = NaElement("volume-space-attributes")
    xi1.child_add(xi2)

    xi2.child_add_string("size","<size>")
    xi2.child_add_string("size-available","<size-available>")
    xi2.child_add_string("size-total","<size-total>")
    xi2.child_add_string("size-used","<size-used>")
    api.child_add_string("max-records", recordlimit)

    xi3 = NaElement("query")
    api.child_add(xi3)

    xi4 = NaElement("volume-attributes")
    xi3.child_add(xi4)

    xi5 = NaElement("volume-id-attributes")
    xi4.child_add(xi5)

    xi5.child_add_string("name", volume)
    api.child_add_string("tag","<tag>")

    xo = s.invoke_elem(api)
    if (xo.results_status() == "failed") :
        print ("Error:\n")
        print (xo.sprintf())
        sys.exit (1)

    print ("Received:\n")
    print (xo.sprintf())

 Can you please help me with resolving this error? 

It works fine in the ZEDI GUI. But it's failing when I make the same call in python.

from netapp.NaElement import NaElement
from netapp.NaServer import NaServer



def volume_space(s, recordlimit, volume):
    api = NaElement("volume-get-iter")

    xi = NaElement("desired-attributes")
    api.child_add(xi)

    xi1 = NaElement("volume-attributes")
    xi.child_add(xi1)

    xi2 = NaElement("volume-space-attributes")
    xi1.child_add(xi2)

    xi2.child_add_string("size","true")
    xi2.child_add_string("size-available","true")
    xi2.child_add_string("size-total","true")
    xi2.child_add_string("size-used","true")
    api.child_add_string("max-records", recordlimit)

    xi3 = NaElement("query")
    api.child_add(xi3)

    xi4 = NaElement("volume-attributes")
    xi3.child_add(xi4)

    xi5 = NaElement("volume-id-attributes")
    xi4.child_add(xi5)

    xi5.child_add_string("name", volume)


    xo = s.invoke_elem(api)
    if (xo.results_status() == "failed") :
        print ("Error:\n")
        print (xo.sprintf())

    print ("Received:\n")
    print (xo.sprintf())

s = NaServer('cdotfiler', 1, 0)
s.set_style('LOGIN')
s.set_transport_type('HTTPS')
s.set_server_type('FILER')
s.set_admin_user('admin', 'pass')

volume_space(s, 20, 'volxxxx')

set the desired values with true  xi2.child_add_string("size","true")

tag is not necessary, you only need it if you have to relauch zapi if you reach maximum records that zapi can return.
