Как создать несколько тегов с одним и тем же именем с иерархией в python 3.x, используя l xml?

Я хочу сгенерировать XML примерно так: 

<linkbase>
  <presentationLink xlink:type="extended" xlink:role="http://www.rbi.org/in/xbrl/2012-12-07/role/Generalinformationaboutreportinginstitution">
    <loc xlink:type="locator" xlink:href="../core/in-rbi-rep.xsd#in-rbi-rep_GeneralInformationAboutReportingInstitutionAbstract" xlink:label="GeneralInformationAboutReportingInstitutionAbstract" xlink:title="GeneralInformationAboutReportingInstitutionAbstract"/>

    <loc xlink:type="locator" xlink:href="../core/in-rbi-rep.xsd#in-rbi-rep_NameOfReportingInstitution" xlink:label="NameOfReportingInstitution" xlink:title="NameOfReportingInstitution"/>

  </presentationLink>

  </presentationLink>
</linkbase>

Я могу сгенерировать теги <presentationLink>, но не могу сгенерировать внутренние теги с порядком. Я думаю, мне нужно будет l oop через атрибут "order" внутри тега <presentationLink>, но как. Выше приведен тезис, который я взял из большого XML, который имеет отношение к вопросу. Мой текущий код выглядит следующим образом: 

from openpyxl import load_workbook ### The tags come from an excel file
from lxml import etree
import xml.etree.ElementTree as xml

wb = load_workbook("t.xlsx")
ws = wb.worksheets[4]
m_row = ws.max_row
m_col = ws.max_column 

xlink = "http://www.w3.org/1999/xlink"
link = "http://www.xbrl.org/2003/linkbase"
role_prefix = "http://www.rbi.org/in/xbrl/2012-12-07/role/"
href_prefix = "in-rbi-alo-role.xsd#"
elem_type = ['extended', 'locator', 'resource', 'arc', 'simple']

ns = {None : link, 'xlink': xlink}
root = etree.Element("linkbase", nsmap = ns)
# print(root)
# print(root.tag)
print(etree.tostring(root, pretty_print=True).decode("utf-8"))

for i in range(1, m_row): 
    cell_objd = ws.cell(row = i+1, column = 4)
    cell_objf = ws.cell(row = i+1, column = 6)
    cell_objh = ws.cell(row = i+1, column = 8)
    if cell_objd.value == 'ELR':
        pl = etree.SubElement(root, "{" + link + "}presentationLink", attrib={"{" + xlink + "}type" : elem_type[0], "{" + xlink + "}role" : role_prefix + cell_objf.value})
        #print(cell_objd.value, cell_objf.value, cell_objh.value)
print(etree.tostring(root, pretty_print=True).decode("utf-8"))

Приведенный выше код генерирует следующее XML: 

<linkbase xmlns="http://www.xbrl.org/2003/linkbase" xmlns:xlink="http://www.w3.org/1999/xlink">
  <roleRef roleRef="http://www.rbi.org/in/xbrl/2012-12-07/role/Generalinformationaboutreportinginstitution" xlink:type="simple" xlink:href="in-rbi-alo-role.xsd#Generalinformationaboutreportinginstitution"/>
  <roleRef roleRef="http://www.rbi.org/in/xbrl/2012-12-07/role/ReportOnAssetsLiabilitiesAndOtherProducts" xlink:type="simple" xlink:href="in-rbi-alo-role.xsd#ReportOnAssetsLiabilitiesAndOtherProducts"/>
  <roleRef roleRef="http://www.rbi.org/in/xbrl/2012-12-07/role/AnnexureIDetailsOfOffBalanceSheetExposures" xlink:type="simple" xlink:href="in-rbi-alo-role.xsd#AnnexureIDetailsOfOffBalanceSheetExposures"/>
  <roleRef roleRef="http://www.rbi.org/in/xbrl/2012-12-07/role/AnnexureII" xlink:type="simple" xlink:href="in-rbi-alo-role.xsd#AnnexureII"/>
  <roleRef roleRef="http://www.rbi.org/in/xbrl/2012-12-07/role/Signatoryinformation" xlink:type="simple" xlink:href="in-rbi-alo-role.xsd#Signatoryinformation"/>
  <presentationLink xlink:type="extended" xlink:role="http://www.rbi.org/in/xbrl/2012-12-07/role/Generalinformationaboutreportinginstitution"/>
  <presentationLink xlink:type="extended" xlink:role="http://www.rbi.org/in/xbrl/2012-12-07/role/ReportOnAssetsLiabilitiesAndOtherProducts"/>
  <presentationLink xlink:type="extended" xlink:role="http://www.rbi.org/in/xbrl/2012-12-07/role/AnnexureIDetailsOfOffBalanceSheetExposures"/>
  <presentationLink xlink:type="extended" xlink:role="http://www.rbi.org/in/xbrl/2012-12-07/role/AnnexureII"/>
  <presentationLink xlink:type="extended" xlink:role="http://www.rbi.org/in/xbrl/2012-12-07/role/Signatoryinformation"/>
</linkbase>

Как вы можете видеть, <presentationLink> генерируется, но я не могу сделать внутренние теги. Я надеюсь, что вопрос ясен. Я могу предоставить точное превосходство, из которого мне нужно сгенерировать XML, если требуется. Любая помощь приветствуется.

Спасибо.
