Something like this :
SQL> declare
  2 
  3    v_xmlinfo      clob;
  4    v_ddl          varchar2(32767) := 'CREATE TABLE mytable ( #COLUMN_LIST# )';
  5    v_column_list  varchar2(4000);
  6 
  7  begin
  8 
  9    v_xmlinfo := dbms_xslprocessor.read2clob('TEST_DIR', 'info.xml');
10 
11    select column_list
12    into v_column_list
13    from xmltable(
14           'string-join(
15              for $i in /INFO
16              return concat($i/Column_Name, " ", $i/Data_Type)
17            , ", "
18            )'
19           passing xmlparse(content v_xmlinfo)
20           columns column_list varchar2(4000) path '.'
21         ) ;
22 
23 
24    v_ddl := replace(v_ddl, '#COLUMN_LIST#', v_column_list);
25    --dbms_output.put_line(v_ddl);
26 
27    execute immediate v_ddl;
28 
29  end;
30  /
PL/SQL procedure successfully completed
SQL> select * from mytable;
COL1 COL2
