How does Simulink store block-to-block connection information in XML file format?

I exported a Simulink model as an XML file (5000+ lines of code). I want to figure out how MATLAB structures it's XML file to connect one block to another. For example I have two blocks in the XML code below: Series RLC Load1 and Series RLC Load2. Let's say these blocks are connected in the Simulink model, where would that be shown in the XML code?

-<Block Name="Series RLC Load1" BlockType="Reference" SID="195">

May I asked how to export a simulink model as an XMl file? Thanks a lot!
