XMLTABLE, different namespace ... parsing problem

I'm trying to parse an XML with different namespaces, I get this xml as a
soap web service response from Netsuite, but I can't get all the values
that I need ...
It is not so clear to me this XPATH syntax!

I need to extract "itemId" and other row information with this SQL

select a.*
FROM
XMLTABLE(
xmlnamespaces (default 'urn:core_2018_1.platform.webservices.netsuite.com',
'http://schemas.xmlsoap.org/soap/envelope/' AS "soap",
'urn:accounting_2018_1.lists.webservices.netsuite.com' as "listact",
'urn:common_2018_1.platform.webservices.netsuite.com' as "platformCommon"
),
'$doc/soap:Envelope/soap:Body/*:searchResponse/searchResult/*:searchRowList/searchRow[*]'

And this is what I get... null for "displayName" and "itemId"
