Adding processing instruction

[davidjamesstone]

I'd like to add a processing instruction to the xml, specifically a stylesheet:

<?xml-stylesheet type="text/xsl" href="./rss-style.xsl"?>

I've had a good look around the code but I can't a way of doing it - anyone have any ideas how to do this (other than post-process the string)

Many thanks

Ths package leverages https://github.com/nashwaan/xml-js to generate the XML, so you'd need to start there.

@paul-uz I believe https://github.com/nashwaan/xml-js already supports this via the "_instruction" key. This lib would need to expose that. I'm happy to issue a PR if I can work it out and it's something you think would be worth adding.

Agree, this would be nice to have this ability.

We want to add xml-stylesheet our RSS feeds for Docusaurus (facebook/docusaurus#9197)

I tweaked this lib code and this seems to do the job:

var base = {
  _declaration: { _attributes: { version: "1.0", encoding: "utf-8" } },
  _instruction: { "xml-stylesheet": 'href="/rss.xsl" type="text/xsl"' },
  rss: {}
};
