How to delete a node in a table in a field with xml without specifying a path?

Question

SQL

There is a table that stores xml

CREATE TABLE T2(id int primary key, Context xml) 

insert into T2 values
(1,'<root>
  <context>
   <alfa>
     <ul></ul>
     <mail>[email protected]</mail>
   </alfa>
    <betta>
     <ul></ul>
    <mail>[email protected]</mail>
    </betta>
  </context>
</root>')
select * from T2;

Is it possible to somehow `drop` everything <mail>[email protected]</mail>
without specifying the path to the element?
