Hi

I am an Xquery newbie and have a question for the experienced. Probably this is a really simple query but it has me stumped for some time now.

If this is the xml I want to parse:

<root>
<Object>
<element>
<Value>10</Value>
</element>
</Object>
<Object>
<element>
<Value>20</Value>
</element>
</Object>
<Object>
<element>
<Value>30</Value>
</element>
</Object>
</root>

Question: What, then, would be the best way to write a query that would parse and:

a) return the "object" element node with the maximum "value "
b) return just the "value" element with the maximum value of "value"

I hope that at least my question is clear and would appreciate any help with this very basic question.

Thanks so much for your time

declare variable $v :=
<root>
<Object>
<element>
<Value>10</Value>
</element>
</Object>
<Object>
<element>
<Value>20</Value>
</element>
</Object>
<Object>
<element>
<Value>30</Value>
</element>
</Object>
</root>;

let $max := fn:max($v/Object/element/Value/text())
return
let $o := $v/Object[element/Value = $max]
return ($o, $o/element/Value)
