My Postgre version its the 8.2. I´ve reached to do the path i wanted, but when i do a explain analyze on the select it return 500 miliseconds. Is this a good search? Is there a way to slow down this time with postgre 8.3? What is a good time for xml xpath´s?

Thanks

Hi everyone,
 
   I´m trying to undestand how to do select with xml path.

I have this xml example:

create table temp(id integer, xml text, Primary Key(id));

<?xml version=\"1.0\" encoding=\"ISO-8859-1\" ?>
                <element1>
                    <element2>
                        <element3 id="1" name="2">
                             <name></name>
                             <element4>
                                 <element5></element5>
                                 <element5></element5>
                                 <element5></element5>
                             </element4>
                        </element3>
                    </element2>
                </element1>

Here go the questions:
1) How can i select all name elements from the xml?
2) How can i select all element3 id´s?
3) How can i select all  element5 that have element3 with attribute name="x"?


Thanks very much.  :)
