How to read fetch xml from app.config

Today i learnt about CDATA that can be used to read fetch xml in our .NET code as described below-



<FetchXML>
     <![CDATA[<fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="false">
        <entity name="account">
          <attribute name="accountid" />
          <filter type="and">
            <condition attribute="name" operator="eq" value="test3443" />
          </filter>
        </entity>
      </fetch>]]>
    </FetchXML>
