I have another example where I want to get the value of "WorkstationID" separately and I'm not getting it. Any suggestions on how to do it?

web.xml

<configuration>
        <appSettings>
                <add key="WorkstationID" value="1769" />
                <add key="ServiceHostID" value="1769" />
                <add key="EGatewayHttpsPort" value="443" />
        </appSettings>
</configuration>

structure to obtain:

map=000001769
