我有一个像下面这样的xml：

def retrieve(self, request, *args, **kwargs):
    """Retrieve a FooBar"""
    return super().retrieve(request, *args, **kwargs)

<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <ns4:EligibilityRequest xmlns:ns5="http://newmmis.eohhs.ma.gov/serviceobjects/versions/1.0/eligresponse" xmlns:ns1="http://newmmis.eohhs.ma.gov/serviceobjects/versions/1.0/mmiscommon" xmlns:ns4="http://newmmis.eohhs.ma.gov/serviceobjects/versions/1.0/eligrequest" xmlns:ns3="http://xmlns.eohhs.ma.gov/newMMIS/ws/2006/05/MemberInfo"> <ns4:transactionsource id_medicaid="100027128782" id_other="00001740934" id_source="HIX"/> <ns4:demographic dte_birth="1986-10-24" cde_sex="F" num_primary_ssn="031725754" cde_citizen="C" cde_race="UNKNOW" cde_ethnicity="UNKNOW" cde_homeless="N" cde_primary_lang="ENG" cde_lang_written="ENG" num_phone_day="4135376954" email="slpaullrn@gmail.com" nam_last="Paull" nam_first="Stephanie" nam_mid_init="L" res_adr_street_1="173 Abbott street" res_adr_city="Springfield" res_adr_state="MA" res_adr_zip_code="01118" mail_adr_street_1="173 Abbott street" mail_adr_city="Springfield" mail_adr_state="MA" mail_adr_zip_code="01118" amt_indv_prem="0" amt_indv_income="0.00" amt_income_fpl="3293.34" pct_income_fpl="166.19" ind_pregnancy=" " cde_tpl_status="S" cde_born_to_st_empl=" "/> <ns4:case num_case="00938195C" cde_case_status="1" hoh_nam_first="Stephanie" hoh_nam_last="Paull" hoh_nam_init="L" amt_family_prem="0" amt_family_mh_prem="12.00" amt_family_prem_assist="0"/> <ns4:eligibility dte_begin_elig="2015-10-12" dte_end_elig="2016-09-06" cde_line="00" cde_elig_status="4" cde_cat="40" amt_gross_income="2470" family_size="4" dte_appl="2015-10-22" cde_region="58" cde_office="555" cde_close_reason="M1"/> <ns4:eligibility dte_begin_elig="2016-08-13" cde_line="00" cde_elig_status="1" cde_cat="AP" amt_gross_income="3293.34" family_size="4" dte_appl="2015-10-22" cde_region="58" cde_office="555" cde_open_reason="01"/> <ns4:uncompdeductible amt_uncmp_deductible="993" dte_effective="2016-08-13"/> </ns4:EligibilityRequest>; 有2个标签。我想删除一个存在cde_close_reason的标记。请指教
