@Lady It actually has a surprisingly small set of rdepends within Ubuntu. Some important packages, like Postgres, but mostly desktop software besides Postgres, Icecast, and Asterisk, and it's hard to say the latter have all too many users. There's Ruby's Nokogiri, but given the near-weekly security updates to that, I might almost prefer someone Rewrite it in Rust (or literally anything).
@aschmitz and yes i would love for someone to rewrite it as well (and make it support XML1.1, and XSLT/XPATH 2.0, and 3.0…), but nobody IS going to do that, because it’s very hard, and in the meantime libxml2 is what is available on every platform, and it still has bugs i would love to see get solved
@aschmitz (i think actually webkit and chrome depends on libxml2/libxslt and gecko has their own c++ implementation.)
