OK, this should do it :
SQL> create table sample_table (
  2   id number,
  3   doc xmltype
  4  );
Table created
SQL> insert into sample_table values(1,
  2  xmltype('<student><name>Mohan</name><name>Doss</name><name>ravi</name></student>')
  3  );
1 row inserted
SQL> insert into sample_table values(2,
  2  xmltype('<root><child1>ABC</child1><child2>XYZ</child2></root>')
  3  );
1 row inserted
SQL> select t.id,
  2         extract(t.doc,'//*[.="ravi"]').getclobval() as content
  3  from sample_table t
  4  where existsnode(t.doc, '//*[.="ravi"]') = 1
  5  ;
        ID CONTENT
         1 <name>ravi</name>
SQL> select t.id,
  2         extract(t.doc,'//*[.="XYZ"]').getclobval() as content
  3  from sample_table t
  4  where existsnode(t.doc, '//*[.="XYZ"]') = 1
  5  ;
        ID CONTENT
         2 <child2>XYZ</child2>
