XML path function

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. :)
