SQL & PL/SQL

I want to select xml element attribute value from a element and its nested element. for example,

I have this

X XMLTYPE := XMLTYPE('<?xml version="1.0" encoding="UTF-8"?>

<request>

    <serviceOrderItems>

        <serviceOrderItem specId="108">

            <entitlements>

                <entitlement id="55"/>

                <entitlement id="990"/>

            </entitlements>

        </serviceOrderItem>

        <serviceOrderItem specId="118">

            <entitlements>

                <entitlement id="551"/>

                <entitlement id="991"/>

            </entitlements>

        </serviceOrderItem>

    </serviceOrderItems>

</request>');

I want to select specId and the id, the result is:

specId   Id

---------------

108     55

108    990

118    551

118    991

I know that by using this I can get specId.

SELECT ExtractValue(Value(p),'/serviceOrderItem/@specId') as specId

        FROM TABLE(XMLSEQUENCE(EXTRACT(X, '//request/serviceOrderItems/serviceOrderItem'))) P)

How do I get specId and Id? Thanks in advance.
