Serialize XML and save to Oracle with C# and ADO

Question:

I would like to know if there is something equivalent in Oracle for this select in SQL Server:

select NickName, ExternalId1 from Basics where externalId1 = @externalId1 for xml auto, elements;

And for this select below:

select
x.n.value('OperationId[1]', 'int'),
x.n.value('Name[1]', 'varchar(50)'),
x.n.value('MaxTime[1]', 'float')
from @xml.nodes('/*[1]') x(n);

For the first one, yes. It stays the same, actually.

select NickName, ExternalId1 
from Basics 
where externalId1 = @externalId1 
for xml auto, elements;

As for the second one, SQL Server supports XPath , but I believe that to work @xml needs to be populated with a query first.
