No need to post your question in every forum…just one will do.
From within RELMA, just search for the panel term you want. Right click the row, then choose “View Panel Children”. That will pop up a window with all the child elements of the panel in a grid. From there you can select all the rows, choose Custom Export to get all the LOINCs in a variety of formats (copy to clipboard, export to excel, etc).
You may also want to check out the LOINC Panel’s and Forms File under Accessory Files from http://loinc.org/downloads for an export of some of the key panels and forms.
