There have been some previous efforts aimed at getting LPeg into NSE.

https://secwiki.org/w/Nmap/Script_Ideas#XML_and_HTML_parsing

But there hasn't been any discussion about it lately. My feeling is that
we have been looking for a good use for LPeg. An XML parsing library
would meet that description. See one of the threads above for a list of
sample use cases for such a library.

It has to work with the version of Lua we ship (5.2), or we can't use
it.
