Create a DataFrame from a XML File

im new to XML and i want to know how to create a dataframe in python from this XML file.

<EXTENDEDPROPERTIES>
<DEBTCONFIGURATION>
    <row Key="guid" Value="2018438038"/>
    <row Key="status" Value="0"/>
    <row Key="forma_pago" Value="DEBITO A CUENTA"/>
    <row Key="monto" Value="23699.1"/>
    <row Key="monto_abono" Value="360.55"/>
    <row Key="entidad" Value="BANCO CAPRICHOSO S.A."/>
    <row Key="tipo" Value="PREST. AUTO"/>
    <row Key="balance" Value="19617.5"/>
    <row Key="KIND_ID" Value="PRINCIPAL"/>
    <row Key="TYPE_ID" Value="CEDULA_IDENTIDAD"/>
    <row Key="CUSTOMER_ID" Value="777-555-888"/>
    <row Key="MEMBER_TYPE" Value="DEUDOR"/>
</DEBTCONFIGURATION>

I have the following code, it creates the DataFrame but when i tried to append the value of the row, i dont know why it keeps coming "None".

I dont know if i have to change de calling argument i.e Attrib.get.

Also i tried changing the attrib.get to find("value").text but it give me the error that it dosnt have the a text attribute.

import pandas as pd 
import xml.etree.ElementTree as ET

xtree = ET.parse("davi_apc.xml")
xroot = xtree.getroot()
 
df_cols = ["guid", "status", "forma_pago", "monto", "monto_abono", "entidad", "tipo", "balance","KIND_ID", "TYPE_ID", "CUSTOMER_ID", "MEMBER_TYPE"]

rows = []

for node in xroot: 
    s_guid = node.attrib.get("guid")
    s_status = node.attrib.get("status")
    s_formapago = node.attrib.get("forma_pago")
    s_monto = node.attrib.get("monto")
    s_monto_abono = node.attrib.get("monto_abono")
    s_entidad = node.attrib.get("entidad")
    s_tipo = node.attrib.get("tipo")
    s_balance = node.attrib.get("balance")
    s_kind_id = node.attrib.get("KIND_ID")
    s_type_id = node.attrib.get("TYPE_ID")
    s_customer_id = node.attrib.get("CUSTOMER_ID")
    s_mebder_type = node.attrib.get("MEMBER_TYPE")
        

rows.append({
    "guid" : s_guid, 
    "status" : s_status, 
    "forma_pago" : s_formapago, 
    "monto" : s_monto, 
    "monto_abono" : s_monto_abono, 
    "entidad" : s_entidad, 
    "tipo" : s_tipo, 
    "balance" : s_balance,
    "KIND_ID" : s_kind_id,
    "TYPE_ID" : s_type_id, 
    "CUSTOMER_ID" : s_customer_id,
    "MEMBER_TYPE" : s_mebder_type
})


out_df = pd.DataFrame(rows, columns = df_cols)

this is the printout of print(rows) [{'guid': None, 'status': None, 'forma_pago': None, 'monto': None, 'monto_abono': None, 'entidad': None, 'tipo': None, 'balance': None, 'KIND_ID': None, 'TYPE_ID': None, 'CUSTOMER_ID': None, 'MEMBER_TYPE': None}]

and this is the printout of the dataframe guid status forma_pago monto monto_abono entidad tipo balance KIND_ID
0 None None None None None None None None None

TYPE_ID CUSTOMER_ID MEMBER_TYPE
0 None None None

Here is a working solution:

1/ remove top line from xml file, I am unsure if the first tag is xml compliant ?

<DEBTCONFIGURATION>
    <row Key="guid" Value="2018438038"/>
    <row Key="status" Value="0"/>
    <row Key="forma_pago" Value="DEBITO A CUENTA"/>
    <row Key="monto" Value="23699.1"/>
    <row Key="monto_abono" Value="360.55"/>
    <row Key="entidad" Value="BANCO CAPRICHOSO S.A."/>
    <row Key="tipo" Value="PREST. AUTO"/>
    <row Key="balance" Value="19617.5"/>
    <row Key="KIND_ID" Value="PRINCIPAL"/>
    <row Key="TYPE_ID" Value="CEDULA_IDENTIDAD"/>
    <row Key="CUSTOMER_ID" Value="777-555-888"/>
    <row Key="MEMBER_TYPE" Value="DEUDOR"/>
</DEBTCONFIGURATION>

2/ code:

import pandas as pd 
import xml.etree.ElementTree as ET

xtree = ET.parse("davi_apc.xml")
xroot = xtree.getroot()
 
rows = [{}]

for node in xroot:
    print(node.attrib)
    rows[0].update({node.attrib['Key']:node.attrib['Value']})
    
out_df = pd.DataFrame(rows)

3/ output for out_df:

out_df.head(10)
         guid status  ...  CUSTOMER_ID MEMBER_TYPE
0  2018438038      0  ...  777-555-888      DEUDOR
