I am having problems when "migrating" my query in which I parse a column with XML stored in it, I am "migrating" from T-SQL to Postgres, since my current development requires it.
My query in T-SQL, takes a column that contains XML that are retrieved from another system, I create the prefixes for the xml with the "XMLNAMESPACES" and then I do an INSERT INTO to save the query in a previously created table, with the subquery I "choose" the values or "columns" that I want to return, cast them and rename them at the same time. After this I cast the "XML" column to "XML" and it is already in "VARCHAR" and finally the .nodes function is called to return the table derived from the query
WITH XMLNAMESPACES('http://www.sat.gob.mx/cfd/4' AS cfdi,
'http://www.sat.gob.mx/Pagos20' AS pago20,
'http://www.sat.gob.mx/TimbreFiscalDigital' AS tfd)
INSERT INTO [CFDI_SON990511MI0_RECIBIDOS].[dbo].[DataXml_SON990511MI0_RepsRecibidos_2023] (UUID, DoctoRelacionado, NumParcialidad, ImpPagado, FePago)
SELECT
prx4_0.*
FROM
(
SELECT
UUID,
x.value('(@IdDocumento)', 'NVARCHAR(64)') AS DoctoRelacionado,
x.value('(@NumParcialidad)', 'TINYINT') AS NumParcialidad,
x.value('(@ImpPagado)', 'DECIMAL(26, 8)') AS ImpPagado,
x.value('(/cfdi:Comprobante/@Fecha)[1]', 'DATETIME') AS FePago
FROM [dbo].[XML]
--El casteo ocurre aqui
CROSS APPLY(SELECT CAST(XML AS XML)) A(TheXml)
--Se llama a la funcion .nodes para retornar la tabla derivada de la consulta
CROSS APPLY TheXml.nodes('/cfdi:Comprobante/cfdi:Complemento/pago20:Pagos/pago20:Pago/pago20:DoctoRelacionado') B(x)
) prx4_0
GO
This is the XML to be able to reproduce:

This is the error I get when I want to perform the query:
SQL Error [2200M]: ERROR: could not parse XML document¶ Detail: line 1: xmlns:schemaLocation: 'http://www.sat.gob.mx/registrofiscal http://www.sat.gob.mx/sitio_internet/cfd/cfdiregistrofiscal/cfdiregistrofiscal.xsd' is not a valid URI¶p://www.sat.gob.mx/sitio_internet/cfd/cfdiregistrofiscal/cfdiregistrofiscal.xsd"¶
I was already investigating my table already generated in T-SQL, it does not give me this error and it is not possible for me to make a replacement for that "URI" since the table is from a provider. I would greatly appreciate any help, if you need more information about the XML, table or query I can provide it.
This my actual table on T-SQL and and it is also the output I expect with the postgres query

There are incorrect xsi:schemaLocation values in the XML.
I had to remove them from the XML.
PostgreSQL XML shredding is similar to Oracle implementation.
