For when you go to a lonely island and survival depends on parsing XML.

This is a rewrite of roxmltree which makes a few API changes and drops some verification steps to enable speed-ups between 40 and 90 percent. It also compares favourably to quick-xml even though it does build a DOM and fully normalizes text and attribute values including entity resolution. For example, using -Ctarget-cpu=native on a Ryzen 5600U, the XML files contained in this repository yield the following measurements:
