HTML page to Lua table - Thomas - 25.02.2017
Hi
Can I convert a webpage (returned as a string from http.request) to a Lua table? M isea is to convert DOM in the same way as json library parse json to table.
Now I parse the webpage using string manipulation functions like match, gsub etc. I don't trust this code so much so I would like to improve my code by a more robust solution. Is there any suitable library in LM?
Thank you
And subquestion: I need to convert the webpage into something LM understands. Which codepage Lua or LM uses internally? Is it UTF8? Is there iconv available in LM?

LuaExpat library for parsing XML is built-in but it probably won't work because most web pages are invalid XML documents.
There are some pure Lua parsers like https://github.com/thenumbernine/htmlparser-lua, but you will have to adapt the code a little bit for it to run in LM.
Web interface uses UTF-8. All Lua string functions work only on byte level so they mostly don't care about encoding. iconv is not provided by default but can be provided as a separate package later.
