curl - how to pull this data?

[ibuddy]

Alrigth so say I want to create a curl script to pull this exact data:

<!-- Start Main Audio --> 

bunch of html coding about 40 lines

<!-- End Main Audio --> 

Alrigth The above shows you where on the page I want to take the code from. Basically the tag starts with <!-- Start Main Audio --> and ends with <!-- End Main Audio -->

so how in curl would I write this to take this information from the start to the finish ?
