Request example:

Answer 1

XML is evil, with JSON there is absolutely no reason to use it unless it's for compatibility with old and legacy applications. There is a parser for the node: https://github.com/fb55/htmlparser2/

Answer 2

Perhaps this is suitable (if you need shaping and parsing xml): https://github.com/dylang/node-xml
Or if you need only parsing: https://github.com/Leonidas-from-XIV/node-xml2js
