Query specification

Hi guys,

I am using the Restful SDK to get the dataproviders query specification (http://server:6405/biprws/raylight/v1/documents/{ID}/dataproviders/DP0/specification). The result XML is something like this:

<queryspec:QuerySpec xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:parameter="http://com.sap.sl.parameter" xmlns:queryspec="http://com.sap.sl.queryspec" dataProviderId="DP0">

    <queryParameters>   

    </queryParameters>

    <queriesTree xsi:type="queryspec:QueryOperatorNode" queryOperator="Union">

        <children xsi:type="queryspec:QueryDataNode">

            <bOQuery name="Query" identifier="_DQwTUS-BEeWGVJVUo9we">

                <resultObjects identifier="DS0.DO4fc" name="asdasdad"/>

                <conditionPart>

                    <conditionTree xsi:type="queryspec:ConditionOperatorNode" logicalOperator="And">

                    </conditionTree>

                </conditionPart>

            </bOQuery>

        </children>

    </queriesTree>

</queryspec:QuerySpec>

I have to parse this XML to identify all the universe objects used by the document (result objects and conditions too). Where can I find the formal schema/specification/documentation for this XML?

Are there any good examples available, to parse this XML?

Thx.
