Despite how ugly xslt may look, and how little it's used, I think it actually solved a problem in parsing xml on streams (xslt 3.0 I think?) in a way that really isn't that simple (or used often) in any standard languages. I have done quite a few xml parsing scripts in python/Julia/etc, but despite xpaths on dom being so much easier to write, the OOM problems are abundant. XSLT I think had some good ideas for making xml parsing more performant while avoiding some of the major issues that crop up when processing huge amounts of data.
