Need some direction on macros.

I once had to overcome the same thing for scraping a site that used a rotating 
cipher of obfuscating links through various js schemes. My solution was 
overkill, but future proof - embed the entire v8 js engine, evaluate the code, 
then extract what was necessary. It's an option. This was before duktape - but 
that would have been better.
