rubygems VS Nokogiri

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.

It seems to have an in-tree libxml 2.11 for XPath support, which was released in 2023-04. Almost every second libxml release comes with a CVE, so I'm curious if there's plans to upgrade the libxml version, since it doesn't use the system libxml (same as nokogiri).

One of the reasons I still use nokogiri is because it puts a lot of effort into keeping libxml updated: https://github.com/sparklemotion/nokogiri/releases

(2.1) Compare tagName in the selector

Apparently Nokogiri implements CSS in a very inefficient way though by collecting ancestors and then converting the CSS into xpath and matching that:

I'd expect that to be an order of magnitude slower than what a browser does.

What's holding me back from going all in with Crystal is I have a lot of pre-existing Ruby code, and porting Ruby code to Crystal can be tricky. For example, Crystal lacks an Enumerator class (aka generators) due to captured block semantics. I also wish the shards ecosystem was a little more mature; for example there's multiple HTML parsing libraries, but none have all of the features that Ruby's Nokogiri has. For new greenfield backend projects, I would totally use Crystal.

Welcome! Ruby isn't exactly "dying", but the hype/popularity is definitely fading. This is primarily because Ruby is no longer "new", most of Ruby's popularity came from Rails, and now Rails is no longer the "new hotness". However, Ruby still has lots of awesome features and lots of awesome other libraries and frameworks, such as the new fancy irb gem that uses reline, nokogiri, chunky_png, the async gems, Dragon Ruby, SciRuby, Ronin, and the new Hanami web framework.
