I need to extract the body node of the xml by using plsql ,below code works fine for Header
extract('/soap:Envelope/soap:Header/child::node()','xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"');
but I could not get the body by this code
extract('/soap:Envelope/soap:Header/soap:Body/child::node()','xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"');
Thank you for any help.

Body and Header are both direct descendant of the root node. You are trying to get a Body node under a Header node.There is no such child node of Header, so you get no result.
The path should be:
extract('/soap:Envelope/soap:Body/child::node()','xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"');
which as part of a PL/SQL block (with made-up table, column and variable names) would get:
declare
l_doc xmltype;
l_body xmltype;
begin
select xml_col into l_doc from your_table;
l_body := l_doc.extract('/soap:Envelope/soap:Body/child::node()',
'xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"');
dbms_output.put_line(l_body.getstringval);
end;

PL/SQL procedure successfully completed.
