insert into xdata values (1,'<values>Infosys</values>');
insert into xdata values (1,'<values>Enterprisedb</values>');
insert into xdata values (1,'<values>Wipro</values>');
postgres=# select * from xdata ;
id | xmlcode
----+-------------------------------
1 | <values>Infosys</values>
1 | <values>Enterprisedb</values>
1 | <values>Wipro</values>

postgres=# update xdata set xmlcode='<values>Infosys-Bangalore</values>' where cast(xpath('//values/text()',xmlcode) as text[]) = '{Infosys}';
