14.8.2 Defining macros to process index content
You will need to parse each index entry to divide it into levels, because the content of each level becomes a separate XML <indexN> element. Mif2Go macro [ProcIXtext] handles this chore. Those parts of the macro that actually end up in output are highlighted in color: green for element content, magenta for element tags. Lines are numbered for reference.
