Question

您好我正在使用SQL并在变量

中具有以下值

<needs xsi:noNamespaceSchemaLocation="../../../../docs/xsd/rx/i2.0/needs-i2.0.xsd"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <Method qid="String" isApplicable="true" location="needs"
        source="needs">
        <Yes>false</Yes>
        <No>true</No>
    </Method>
    <S_Needs qid="String" isApplicable="true" location="needs"
        source="needs">
        <N_Value type="String" id="String" from="String"> NEED THIS VALUE </N_Value>
    </S_Needs>
    <Testing qid="String" isApplicable="true" location="needs"
        source="needs">
        <Yes>false</Yes>
        <No>false</No>
        <Defaults>true</Defaults>
    </Testing>
</needs>

路线是需要，S_Needs，N_Value我需要N_Value我怎样才能得到这个值
