Question

Does anyone knows, how to represent a complex electric circuit with loops, flows in XML format?

The efficient way to parse it?

Efficient data structure to store parsing data, from which we can again create XML?

Thank you.

There are standard XML parsers (e.g. DOM for in-memory and SAX for event-based processing) that you should be using.

You can represent a circuit in XML pretty easily – it’s nothing more than nodes and connectors of different types. Write a schema that represents them.

I’m picturing something simple, like this one for a serial RC circuit:

<circuit>
    <node id="1"/>
    <node id="2"/>
    <node id="3"/>
    <connector id="1" type="resistor" value="10" units="ohm">
        <start-node>1</start-node>
        <end-node>2</start-node>
    </connector>
    <connector id="2" type="capacitor" value="10" units="farad">
        <start-node>2</start-node>
        <end-node>3</start-node>
    </connector>
    <connector id="3" type="battery" value="10" units="volts">
        <start-node>3</start-node>
        <end-node>1</start-node>
    </connector>
</circuit>
